import aws_cdk.aws_amplify as amplify

cfn_branch = amplify.CfnBranch(self, "MyCfnBranch",

Create a new AWS::Amplify::Branch.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
app_id (str) – The unique ID for an Amplify app. Length Constraints: Minimum length of 1. Maximum length of 20. Pattern: d[a-z0-9]+
branch_name (str) – The name for the branch. Length Constraints: Minimum length of 1. Maximum length of 255. Pattern: (?s).+
basic_auth_config (Union[IResolvable, BasicAuthConfigProperty, Dict[str, Any], None]) – The basic authorization credentials for a branch of an Amplify app. You must base64-encode the authorization credentials and provide them in the format user:password .
build_spec (Optional[str]) – The build specification (build spec) for the branch. Length Constraints: Minimum length of 1. Maximum length of 25000. Pattern: (?s).+
description (Optional[str]) – The description for the branch that is part of an Amplify app. Length Constraints: Maximum length of 1000. Pattern: (?s).*
enable_auto_build (Union[bool, IResolvable, None]) – Enables auto building for the branch.
enable_performance_mode (Union[bool, IResolvable, None]) – Enables performance mode for the branch. Performance mode optimizes for faster hosting performance by keeping content cached at the edge for a longer interval. When performance mode is enabled, hosting configuration or code changes can take up to 10 minutes to roll out.
enable_pull_request_preview (Union[bool, IResolvable, None]) – Specifies whether Amplify Hosting creates a preview for each pull request that is made for this branch. If this property is enabled, Amplify deploys your app to a unique preview URL after each pull request is opened. Development and QA teams can use this preview to test the pull request before it’s merged into a production or integration branch. To provide backend support for your preview, Amplify automatically provisions a temporary backend environment that it deletes when the pull request is closed. If you want to specify a dedicated backend environment for your previews, use the PullRequestEnvironmentName property. For more information, see Web Previews in the AWS Amplify Hosting User Guide .
environment_variables (Union[IResolvable, Sequence[Union[IResolvable, EnvironmentVariableProperty, Dict[str, Any]]], None]) – The environment variables for the branch.
framework (Optional[str]) – The framework for the branch.
pull_request_environment_name (Optional[str]) – If pull request previews are enabled for this branch, you can use this property to specify a dedicated backend environment for your previews. For example, you could specify an environment named prod , test , or dev that you initialized with the Amplify CLI and mapped to this branch. To enable pull request previews, set the EnablePullRequestPreview property to true . If you don’t specify an environment, Amplify Hosting provides backend support for each preview by automatically provisioning a temporary backend environment. Amplify Hosting deletes this environment when the pull request is closed. For more information about creating backend environments, see Feature Branch Deployments and Team Workflows in the AWS Amplify Hosting User Guide . Length Constraints: Maximum length of 20. Pattern: (?s).*
stage (Optional[str]) – Describes the current stage for the branch. Valid Values: PRODUCTION | BETA | DEVELOPMENT | EXPERIMENTAL | PULL_REQUEST
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The tag for the branch.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

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 (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)
