Bases: Resource

A database instance.

Resource:

AWS::DocDB::DBInstance

ExampleMetadata:

fixture=_generated

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk as cdk
from aws_cdk import aws_docdb as docdb
from aws_cdk import aws_ec2 as ec2

# database_cluster: docdb.DatabaseCluster
# instance_type: ec2.InstanceType

database_instance = docdb.DatabaseInstance(self, "MyDatabaseInstance",
    cluster=database_cluster,
    instance_type=instance_type,

    # the properties below are optional
    auto_minor_version_upgrade=False,
    availability_zone="availabilityZone",
    db_instance_name="dbInstanceName",
    enable_performance_insights=False,
    preferred_maintenance_window="preferredMaintenanceWindow",
    removal_policy=cdk.RemovalPolicy.DESTROY
)
Parameters:
  • scope (Construct) –

  • id (str) –

  • cluster (IDatabaseCluster) – The DocumentDB database cluster the instance should launch into.

  • instance_type (InstanceType) – The name of the compute and memory capacity classes.

  • auto_minor_version_upgrade (Optional[bool]) – Indicates that minor engine upgrades are applied automatically to the DB instance during the maintenance window. Default: true

  • availability_zone (Optional[str]) – The name of the Availability Zone where the DB instance will be located. Default: - no preference

  • db_instance_name (Optional[str]) – A name for the DB instance. If you specify a name, AWS CloudFormation converts it to lowercase. Default: - a CloudFormation generated name

  • enable_performance_insights (Optional[bool]) – A value that indicates whether to enable Performance Insights for the DB Instance. Default: - false

  • preferred_maintenance_window (Optional[str]) – The weekly time range (in UTC) during which system maintenance can occur. Format: ddd:hh24:mi-ddd:hh24:mi Constraint: Minimum 30-minute window Default: - a 30-minute window selected at random from an 8-hour block of time for each AWS Region, occurring on a random day of the week. To see the time blocks available, see https://docs.aws.amazon.com/documentdb/latest/developerguide/db-instance-maintain.html#maintenance-window

  • removal_policy (Optional[RemovalPolicy]) – The CloudFormation policy to apply when the instance is removed from the stack or replaced during an update. Default: RemovalPolicy.Retain

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (RemovalPolicy) –

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

cluster

The instance’s database cluster.

db_instance_endpoint_address

The instance endpoint address.

Inheritdoc:

true

db_instance_endpoint_port

The instance endpoint port.

Inheritdoc:

true

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

instance_arn

The instance arn.

instance_endpoint

The instance endpoint.

Inheritdoc:

true

instance_identifier

The instance identifier.

Inheritdoc:

true

node

The tree node.

stack

The stack in which this resource is defined.

Static Methods

classmethod from_database_instance_attributes(scope, id, *, instance_endpoint_address, instance_identifier, port)

Import an existing database instance.

Parameters:
  • scope (Construct) –

  • id (str) –

  • instance_endpoint_address (str) – The endpoint address.

  • instance_identifier (str) – The instance identifier.

  • port (Union[int, float]) – The database port.

Return type:

IDatabaseInstance

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:

x (Any) – Any object.

Return type:

bool

Returns:

true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
