  • :publicly_accessible (Boolean)

    A value that indicates whether the DB instance is publicly accessible.

    When the DB instance is publicly accessible, its DNS endpoint resolves to the private IP address from within the DB instance's VPC, and to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses, and that public access is not permitted if the security group assigned to the DB instance doesn't permit it.

    When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

    Default: The default behavior varies depending on whether DBSubnetGroupName is specified.

    If DBSubnetGroupName isn't specified, and PubliclyAccessible isn't specified, the following applies:

    • If the default VPC in the target region doesn’t have an Internet gateway attached to it, the DB instance is private.

    • If the default VPC in the target region has an Internet gateway attached to it, the DB instance is public.

    If DBSubnetGroupName is specified, and PubliclyAccessible isn't specified, the following applies:

    • If the subnets are part of a VPC that doesn’t have an Internet gateway attached to it, the DB instance is private.

    • If the subnets are part of a VPC that has an Internet gateway attached to it, the DB instance is public.

    The identifier of the DB cluster that the instance will belong to.

  • :storage_type (String)

    Specifies the storage type to be associated with the DB instance.

    Valid values: standard | gp2 | io1

    If you specify io1, you must also include a value for the Iops parameter.

    Default: io1 if the Iops parameter is specified, otherwise gp2

  • :tde_credential_arn (String)

    The ARN from the key store with which to associate the instance for TDE encryption.

  • :tde_credential_password (String)

    The password for the given ARN from the key store in order to access the device.

  • :storage_encrypted (Boolean)

    A value that indicates whether the DB instance is encrypted. By default, it isn't encrypted.

    Amazon Aurora

    Not applicable. The encryption for DB instances is managed by the DB cluster.

  • :kms_key_id (String)

    The AWS KMS key identifier for an encrypted DB instance.

    The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB instance with the same AWS account that owns the KMS encryption key used to encrypt the new DB instance, then you can use the KMS key alias instead of the ARN for the KM encryption key.

    Amazon Aurora

    Not applicable. The KMS key identifier is managed by the DB cluster. For more information, see CreateDBCluster.

    If StorageEncrypted is enabled, and you do not specify a value for the KmsKeyId parameter, then Amazon RDS will use your default encryption key. AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.

  • :domain (String)

    The Active Directory directory ID to create the DB instance in. Currently, only Microsoft SQL Server and Oracle DB instances can be created in an Active Directory Domain.

    For Microsoft SQL Server DB instances, Amazon RDS can use Windows Authentication to authenticate users that connect to the DB instance. For more information, see Using Windows Authentication with an Amazon RDS DB Instance Running Microsoft SQL Server in the Amazon RDS User Guide.

    For Oracle DB instances, Amazon RDS can use Kerberos Authentication to authenticate users that connect to the DB instance. For more information, see Using Kerberos Authentication with Amazon RDS for Oracle in the Amazon RDS User Guide.

  • :copy_tags_to_snapshot (Boolean)

    A value that indicates whether to copy tags from the DB instance to snapshots of the DB instance. By default, tags are not copied.

    Amazon Aurora

    Not applicable. Copying tags to snapshots is managed by the DB cluster. Setting this value for an Aurora DB instance has no effect on the DB cluster setting.

  • :monitoring_interval (Integer)

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If MonitoringRoleArn is specified, then you must also set MonitoringInterval to a value other than 0.

    Valid Values: 0, 1, 5, 10, 15, 30, 60

  • :monitoring_role_arn (String)

    The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, go to Setting Up and Enabling Enhanced Monitoring in the Amazon RDS User Guide.

    If MonitoringInterval is set to a value other than 0, then you must supply a MonitoringRoleArn value.

  • :domain_iam_role_name (String)

    Specify the name of the IAM role to be used when making API calls to the Directory Service.

  • :promotion_tier (Integer)

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :db_instance_identifier (required, String)

    The DB instance identifier of the read replica. This identifier is the unique key that identifies a DB instance. This parameter is stored as a lowercase string.

  • :db_instance_class (String)

    The compute and memory capacity of the read replica, for example, db.m4.large. Not all DB instance classes are available in all AWS Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide.

    Default: Inherits from the source DB instance.

  • :availability_zone (String)

    The Availability Zone (AZ) where the read replica will be created.

    Default: A random, system-chosen Availability Zone in the endpoint's AWS Region.

    Example: us-east-1d

  • :port (Integer)

    The port number that the DB instance uses for connections.

    Default: Inherits from the source DB instance

    Valid Values: 1150-65535

  • :multi_az (Boolean)

    A value that indicates whether the read replica is in a Multi-AZ deployment.

    You can create a read replica as a Multi-AZ DB instance. RDS creates a standby of your replica in another Availability Zone for failover support for the replica. Creating your read replica as a Multi-AZ DB instance is independent of whether the source database is a Multi-AZ DB instance.

  • :auto_minor_version_upgrade (Boolean)

    A value that indicates whether minor engine upgrades are applied automatically to the read replica during the maintenance window.

    Default: Inherits from the source DB instance

  • :iops (Integer)

    The amount of Provisioned IOPS (input/output operations per second) to be initially allocated for the DB instance.

  • :option_group_name (String)

    The option group the DB instance is associated with. If omitted, the option group associated with the source instance is used.

    For SQL Server, you must use the option group associated with the source instance.

  • :db_parameter_group_name (String)

    The name of the DB parameter group to associate with this DB instance.

    If you do not specify a value for DBParameterGroupName, then Amazon RDS uses the DBParameterGroup of source DB instance for a same region read replica, or the default DBParameterGroup for the specified DB engine for a cross region read replica.

    Currently, specifying a parameter group for this operation is only supported for Oracle DB instances.

    Constraints:

    • Must be 1 to 255 letters, numbers, or hyphens.

    • First character must be a letter

    • Can't end with a hyphen or contain two consecutive hyphens

  • :publicly_accessible (Boolean)

    A value that indicates whether the DB instance is publicly accessible.

    When the DB instance is publicly accessible, its DNS endpoint resolves to the private IP address from within the DB instance's VPC, and to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses, and that public access is not permitted if the security group assigned to the DB instance doesn't permit it.

    When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

    For more information, see CreateDBInstance.

  • :tags (Array<Types::Tag>)

    A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.

  • :db_subnet_group_name (String)

    Specifies a DB subnet group for the DB instance. The new DB instance is created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance isn't created in a VPC.

    Constraints:

    • Can only be specified if the source DB instance identifier specifies a DB instance in another AWS Region.

    • If supplied, must match the name of an existing DBSubnetGroup.

    • The specified DB subnet group must be in the same AWS Region in which the operation is running.

    • All read replicas in one AWS Region that are created from the same source DB instance must either:>

      • Specify DB subnet groups from the same VPC. All these read replicas are created in the same VPC.

      • Not specify a DB subnet group. All these read replicas are created outside of any VPC.

    Example: mySubnetgroup

  • :vpc_security_group_ids (Array<String>)

    A list of EC2 VPC security groups to associate with the read replica.

    Default: The default EC2 VPC security group for the DB subnet group's VPC.

  • :storage_type (String)

    Specifies the storage type to be associated with the read replica.

    Valid values: standard | gp2 | io1

    If you specify io1, you must also include a value for the Iops parameter.

    Default: io1 if the Iops parameter is specified, otherwise gp2

  • :copy_tags_to_snapshot (Boolean)

    A value that indicates whether to copy all tags from the read replica to snapshots of the read replica. By default, tags are not copied.

  • :monitoring_interval (Integer)

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the read replica. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If MonitoringRoleArn is specified, then you must also set MonitoringInterval to a value other than 0.

    Valid Values: 0, 1, 5, 10, 15, 30, 60

  • :monitoring_role_arn (String)

    The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, go to To create an IAM role for Amazon RDS Enhanced Monitoring in the Amazon RDS User Guide.

    If MonitoringInterval is set to a value other than 0, then you must supply a MonitoringRoleArn value.

  • :kms_key_id (String)

    The AWS KMS key ID for an encrypted read replica. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

    If you create an encrypted read replica in the same AWS Region as the source DB instance, then you do not have to specify a value for this parameter. The read replica is encrypted with the same KMS key as the source DB instance.

    If you create an encrypted read replica in a different AWS Region, then you must specify a KMS key for the destination AWS Region. KMS encryption keys are specific to the AWS Region that they are created in, and you can't use encryption keys from one AWS Region in another AWS Region.

    You can't create an encrypted read replica from an unencrypted DB instance.

  • :pre_signed_url (String)

    The URL that contains a Signature Version 4 signed request for the CreateDBInstanceReadReplica API action in the source AWS Region that contains the source DB instance.

    You must specify this parameter when you create an encrypted read replica from another AWS Region by using the Amazon RDS API. Don't specify PreSignedUrl when you are creating an encrypted read replica in the same AWS Region.

    The presigned URL must be a valid request for the CreateDBInstanceReadReplica API action that can be executed in the source AWS Region that contains the encrypted source DB instance. The presigned URL request must contain the following parameter values:

    • DestinationRegion - The AWS Region that the encrypted read replica is created in. This AWS Region is the same one where the CreateDBInstanceReadReplica action is called that contains this presigned URL.

      For example, if you create an encrypted DB instance in the us-west-1 AWS Region, from a source DB instance in the us-east-2 AWS Region, then you call the CreateDBInstanceReadReplica action in the us-east-1 AWS Region and provide a presigned URL that contains a call to the CreateDBInstanceReadReplica action in the us-west-2 AWS Region. For this example, the DestinationRegion in the presigned URL must be set to the us-east-1 AWS Region.

    • KmsKeyId - The AWS KMS key identifier for the key to use to encrypt the read replica in the destination AWS Region. This is the same identifier for both the CreateDBInstanceReadReplica action that is called in the destination AWS Region, and the action contained in the presigned URL.

    • SourceDBInstanceIdentifier - The DB instance identifier for the encrypted DB instance to be replicated. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are creating an encrypted read replica from a DB instance in the us-west-2 AWS Region, then your SourceDBInstanceIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115.

    To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.

    If you are using an AWS SDK tool or the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a presigned URL that is a valid request for the operation that can be executed in the source AWS Region.

    SourceRegion isn't supported for SQL Server, because SQL Server on Amazon RDS doesn't support cross-region read replicas.

  • :enable_iam_database_authentication (Boolean)

    A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled. For information about the supported DB engines, see CreateDBInstance.

    For more information about IAM database authentication, see IAM Database Authentication for MySQL and PostgreSQL in the Amazon RDS User Guide.

  • :enable_performance_insights (Boolean)

    A value that indicates whether to enable Performance Insights for the read replica.

    For more information, see Using Amazon Performance Insights in the Amazon RDS User Guide.

  • :performance_insights_kms_key_id (String)

    The AWS KMS key identifier for encryption of Performance Insights data. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

    If you do not specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses your default encryption key. AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.

  • :performance_insights_retention_period (Integer)

    The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

  • :enable_cloudwatch_logs_exports (Array<String>)

    The list of logs that the new DB instance is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon RDS User Guide.

  • :processor_features (Array<Types::ProcessorFeature>)

    The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

  • :use_default_processor_features (Boolean)

    A value that indicates whether the DB instance class of the DB instance uses its default processor features.

  • :deletion_protection (Boolean)

    A value that indicates whether the DB instance has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled. For more information, see Deleting a DB Instance.

  • :domain (String)

    The Active Directory directory ID to create the DB instance in.

    For Oracle DB instances, Amazon RDS can use Kerberos authentication to authenticate users that connect to the DB instance. For more information, see Using Kerberos Authentication with Amazon RDS for Oracle in the Amazon RDS User Guide.

    For Microsoft SQL Server DB instances, Amazon RDS can use Windows Authentication to authenticate users that connect to the DB instance. For more information, see Using Windows Authentication with an Amazon RDS DB Instance Running Microsoft SQL Server in the Amazon RDS User Guide.

  • :domain_iam_role_name (String)

    Specify the name of the IAM role to be used when making API calls to the Directory Service.

  • :destination_region (String)
  • :source_region (String)

    The source region of the snapshot. This is only needed when the shapshot is encrypted and in a different region.

  • :allocated_storage (Integer)

    The new amount of storage (in gibibytes) to allocate for the DB instance.

    For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

    For the valid values for allocated storage for each engine, see CreateDBInstance.

  • :db_instance_class (String)

    The new compute and memory capacity of the DB instance, for example, db.m4.large. Not all DB instance classes are available in all AWS Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide.

    Default: Uses existing setting

  • :db_subnet_group_name (String)

    The new DB subnet group for the DB instance. You can use this parameter to move your DB instance to a different VPC. If your DB instance isn't in a VPC, you can also use this parameter to move your DB instance into a VPC. For more information, see Updating the VPC for a DB Instance in the Amazon RDS User Guide.

    Changing the subnet group causes an outage during the change. The change is applied during the next maintenance window, unless you enable ApplyImmediately.

    Constraints: If supplied, must match the name of an existing DBSubnetGroup.

    Example: mySubnetGroup

  • :db_security_groups (Array<String>)

    A list of DB security groups to authorize on this DB instance. Changing this setting doesn't result in an outage and the change is asynchronously applied as soon as possible.

    Constraints:

    • If supplied, must match existing DBSecurityGroups.

    ^

  • :vpc_security_group_ids (Array<String>)

    A list of EC2 VPC security groups to authorize on this DB instance. This change is asynchronously applied as soon as possible.

    Amazon Aurora

    Constraints:

    • If supplied, must match existing VpcSecurityGroupIds.

    ^

  • :apply_immediately (Boolean)

    A value that indicates whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the DB instance. By default, this parameter is disabled.

    If this parameter is disabled, changes to the DB instance are applied during the next maintenance window. Some parameter changes can cause an outage and are applied on the next call to RebootDBInstance, or the next failure reboot. Review the table of parameters in Modifying a DB Instance in the Amazon RDS User Guide. to see the impact of enabling or disabling ApplyImmediately for each modified parameter and to determine when the changes are applied.

  • :master_user_password (String)

    The new password for the master user. The password can include any printable ASCII character except "/", """, or "@".

    Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible. Between the time of the request and the completion of the request, the MasterUserPassword element exists in the PendingModifiedValues element of the operation response.

    Amazon Aurora

    Not applicable. The password for the master user is managed by the DB cluster. For more information, see ModifyDBCluster.

    Default: Uses existing setting

    MariaDB

    Constraints: Must contain from 8 to 41 characters.

    Microsoft SQL Server

    Constraints: Must contain from 8 to 128 characters.

    Oracle

    Constraints: Must contain from 8 to 30 characters.

    PostgreSQL

    Constraints: Must contain from 8 to 128 characters.

    Amazon RDS API actions never return the password, so this action provides a way to regain access to a primary instance user if the password is lost. This includes restoring privileges that might have been accidentally revoked.

  • :db_parameter_group_name (String)

    The name of the DB parameter group to apply to the DB instance. Changing this setting doesn't result in an outage. The parameter group name itself is changed immediately, but the actual parameter changes are not applied until you reboot the instance without failover. In this case, the DB instance isn't rebooted automatically and the parameter changes isn't applied during the next maintenance window.

    Default: Uses existing setting

    Constraints: The DB parameter group must be in the same DB parameter group family as this DB instance.

  • :backup_retention_period (Integer)

    The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

    Changing this parameter can result in an outage if you change from 0 to a non-zero value or from a non-zero value to 0. These changes are applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If you change the parameter from one non-zero value to another non-zero value, the change is asynchronously applied as soon as possible.

    Amazon Aurora

    Not applicable. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

    Default: Uses existing setting

    Constraints:

    • Must be a value from 0 to 35

    • Can be specified for a MySQL read replica only if the source is running MySQL 5.6 or later

    The daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod parameter. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.

    Amazon Aurora

    Not applicable. The daily time range for creating automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

    Constraints:

    • Must be in the format hh24:mi-hh24:mi

    • Must be in Universal Time Coordinated (UTC)

    • Must not conflict with the preferred maintenance window

    • Must be at least 30 minutes

  • :preferred_maintenance_window (String)

    The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn't result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance. If moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure pending changes are applied.

    Default: Uses existing setting

    Format: ddd:hh24:mi-ddd:hh24:mi

    Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun

    Constraints: Must be at least 30 minutes

  • :multi_az (Boolean)

  • :engine_version (String)

    The version number of the database engine to upgrade to. Changing this parameter results in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is eanbled for this request.

    For major version upgrades, if a nondefault DB parameter group is currently in use, a new DB parameter group in the DB parameter group family for the new engine version must be specified. The new DB parameter group can be the default for that DB parameter group family.

    For information about valid engine versions, see CreateDBInstance, or call DescribeDBEngineVersions.

  • :allow_major_version_upgrade (Boolean)

    A value that indicates whether major version upgrades are allowed. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.

    Constraints: Major version upgrades must be allowed when specifying a value for the EngineVersion parameter that is a different major version than the DB instance's current version.

  • :auto_minor_version_upgrade (Boolean)

    A value that indicates whether minor version upgrades are applied automatically to the DB instance during the maintenance window. Changing this parameter doesn't result in an outage except in the following case and the change is asynchronously applied as soon as possible. An outage results if this parameter is enabled during the maintenance window, and a newer minor version is available, and RDS has enabled auto patching for that engine version.

  • :license_model (String)

    The license model for the DB instance.

    Valid values: license-included | bring-your-own-license | general-public-license

  • :iops (Integer)

    The new Provisioned IOPS (I/O operations per second) value for the RDS instance.

    Changing this setting doesn't result in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If you are migrating from Provisioned IOPS to standard storage, set this value to 0. The DB instance will require a reboot for the change in storage type to take effect.

    If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a read replica for the instance, and creating a DB snapshot of the instance.

    Constraints: For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

    Default: Uses existing setting

  • :option_group_name (String)

    Indicates that the DB instance should be associated with the specified option group. Changing this parameter doesn't result in an outage except in the following case and the change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.

    Permanent options, such as the TDE option for Oracle Advanced Security TDE, can't be removed from an option group, and that option group can't be removed from a DB instance once it is associated with a DB instance

  • :new_db_instance_identifier (String)

    The new DB instance identifier for the DB instance when renaming a DB instance. When you change the DB instance identifier, an instance reboot occurs immediately if you enable ApplyImmediately, or will occur during the next maintenance window if you disable Apply Immediately. This value is stored as a lowercase string.

    Constraints:

    • Must contain from 1 to 63 letters, numbers, or hyphens.

    • The first character must be a letter.

    • Can't end with a hyphen or contain two consecutive hyphens.

    Example: mydbinstance

  • :storage_type (String)

    Specifies the storage type to be associated with the DB instance.

    If you specify Provisioned IOPS (io1), you must also include a value for the Iops parameter.

    If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a read replica for the instance, and creating a DB snapshot of the instance.

    Valid values: standard | gp2 | io1

    Default: io1 if the Iops parameter is specified, otherwise gp2

  • :tde_credential_arn (String)

    The ARN from the key store with which to associate the instance for TDE encryption.

  • :tde_credential_password (String)

    The password for the given ARN from the key store in order to access the device.

  • :ca_certificate_identifier (String)

    Indicates the certificate that needs to be associated with the instance.

  • :domain (String)

    The Active Directory directory ID to move the DB instance to. Specify none to remove the instance from its current domain. The domain must be created prior to this operation. Currently, only Microsoft SQL Server and Oracle DB instances can be created in an Active Directory Domain.

    For Microsoft SQL Server DB instances, Amazon RDS can use Windows Authentication to authenticate users that connect to the DB instance. For more information, see Using Windows Authentication with an Amazon RDS DB Instance Running Microsoft SQL Server in the Amazon RDS User Guide.

    For Oracle DB instances, Amazon RDS can use Kerberos authentication to authenticate users that connect to the DB instance. For more information, see Using Kerberos Authentication with Amazon RDS for Oracle in the Amazon RDS User Guide.

  • :copy_tags_to_snapshot (Boolean)

    A value that indicates whether to copy all tags from the DB instance to snapshots of the DB instance. By default, tags are not copied.

    Amazon Aurora

    Not applicable. Copying tags to snapshots is managed by the DB cluster. Setting this value for an Aurora DB instance has no effect on the DB cluster setting. For more information, see ModifyDBCluster.

  • :monitoring_interval (Integer)

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If MonitoringRoleArn is specified, then you must also set MonitoringInterval to a value other than 0.

    Valid Values: 0, 1, 5, 10, 15, 30, 60

  • :db_port_number (Integer)

    The port number on which the database accepts connections.

    The value of the DBPortNumber parameter must not match any of the port values specified for options in the option group for the DB instance.

    Your database will restart when you change the DBPortNumber value regardless of the value of the ApplyImmediately parameter.

    MySQL

    Default: 3306

    Valid values: 1150-65535

    MariaDB

    Default: 3306

    Amazon Aurora

    Default: 3306

    Valid values: 1150-65535

  • :publicly_accessible (Boolean)

    A value that indicates whether the DB instance is publicly accessible.

    When the DB instance is publicly accessible, its DNS endpoint resolves to the private IP address from within the DB instance's VPC, and to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses, and that public access is not permitted if the security group assigned to the DB instance doesn't permit it.

    When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

    PubliclyAccessible only applies to DB instances in a VPC. The DB instance must be part of a public subnet and PubliclyAccessible must be enabled for it to be publicly accessible.

    Changes to the PubliclyAccessible parameter are applied immediately regardless of the value of the ApplyImmediately parameter.

  • :monitoring_role_arn (String)

    The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, go to To create an IAM role for Amazon RDS Enhanced Monitoring in the Amazon RDS User Guide.

    If MonitoringInterval is set to a value other than 0, then you must supply a MonitoringRoleArn value.

  • :domain_iam_role_name (String)

    The name of the IAM role to use when making API calls to the Directory Service.

  • :promotion_tier (Integer)

    A value that specifies the order in which an Aurora Replica is promoted to the primary instance after a failure of the existing primary instance. For more information, see Fault Tolerance for an Aurora DB Cluster in the Amazon Aurora User Guide.

    Default: 1

    Valid Values: 0 - 15

  • :enable_iam_database_authentication (Boolean)

    A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled. For information about the supported DB engines, see CreateDBInstance.

#snapshots(options = {}) ⇒ DBSnapshot::Collection

Examples:

Request syntax with placeholder values


snapshots = db_instance.snapshots({
  db_snapshot_identifier: "String",
  snapshot_type: "String",
  filters: [
    {
      name: "String", # required
      values: ["String"], # required
    },
  ],
  include_shared: false,
  include_public: false,
  dbi_resource_id: "String",
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :db_snapshot_identifier (String)

    A specific DB snapshot identifier to describe. This parameter can't be used in conjunction with DBInstanceIdentifier. This value is stored as a lowercase string.

    Constraints:

    • If supplied, must match the identifier of an existing DBSnapshot.

    • If this identifier is for an automated snapshot, the SnapshotType parameter must also be specified.

  • :snapshot_type (String)

    The type of snapshots to be returned. You can specify one of the following values:

    • automated - Return all DB snapshots that have been automatically taken by Amazon RDS for my AWS account.

    • manual - Return all DB snapshots that have been taken by my AWS account.

    • shared - Return all manual DB snapshots that have been shared to my AWS account.

    • public - Return all DB snapshots that have been marked as public.

    • awsbackup - Return the DB snapshots managed by the AWS Backup service.

      For information about AWS Backup, see the AWS Backup Developer Guide.

      The awsbackup type does not apply to Aurora.

    If you don't specify a SnapshotType value, then both automated and manual snapshots are returned. Shared and public DB snapshots are not included in the returned results by default. You can include shared snapshots with these results by enabling the IncludeShared parameter. You can include public snapshots with these results by enabling the IncludePublic parameter.

    The IncludeShared and IncludePublic parameters don't apply for SnapshotType values of manual or automated. The IncludePublic parameter doesn't apply when SnapshotType is set to shared. The IncludeShared parameter doesn't apply when SnapshotType is set to public.

  • :filters (Array<Types::Filter>)

    A filter that specifies one or more DB snapshots to describe.

    Supported filters:

    • db-instance-id - Accepts DB instance identifiers and DB instance Amazon Resource Names (ARNs).

    • db-snapshot-id - Accepts DB snapshot identifiers.

    • dbi-resource-id - Accepts identifiers of source DB instances.

    • snapshot-type - Accepts types of DB snapshots.

    • engine - Accepts names of database engines.

  • :include_shared (Boolean)

    A value that indicates whether to include shared manual DB cluster snapshots from other AWS accounts that this AWS account has been given permission to copy or restore. By default, these snapshots are not included.

    You can give an AWS account permission to restore a manual DB snapshot from another AWS account by using the ModifyDBSnapshotAttribute API action.

  • :include_public (Boolean)

    A value that indicates whether to include manual DB cluster snapshots that are public and can be copied or restored by any AWS account. By default, the public snapshots are not included.

    You can share a manual DB snapshot as public by using the ModifyDBSnapshotAttribute API.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {})

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10

    Maximum number of

  • :delay (Integer) — default: 10

    Delay between each

  • :before_attempt (Proc) — default: nil

    Callback

  • :before_wait (Proc) — default: nil

    Callback

Yield Parameters:

  • resource (Resource)

    to be used in the waiting condition.

Returns:

  • (Resource)

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError)

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError)

    Raised when the resource does not
