Deployment

class aws_cdk.aws_apigateway.Deployment(scope, id, *, api, description=None, retain_deployments=None, stage_name=None)

Bases: Resource

A Deployment of a REST API.

An immutable representation of a RestApi resource that can be called by users using Stages. A deployment must be associated with a Stage for it to be callable over the Internet.

Normally, you don’t need to define deployments manually. The RestApi construct manages a Deployment resource that represents the latest model. It can be accessed through restApi.latestDeployment (unless deploy: false is set when defining the RestApi).

If you manually define this resource, you will need to know that since deployments are immutable, as long as the resource’s logical ID doesn’t change, the deployment will represent the snapshot in time in which the resource was created. This means that if you modify the RestApi model (i.e. add methods or resources), these changes will not be reflected unless a new deployment resource is created.

To achieve this behavior, the method addToLogicalId(data) can be used to augment the logical ID generated for the deployment resource such that it will include arbitrary data. This is done automatically for the restApi.latestDeployment deployment.

Furthermore, since a deployment does not reference any of the REST API resources and methods, CloudFormation will likely provision it before these resources are created, which means that it will represent a “half-baked” model. Use the node.addDependency(dep) method to circumvent that. This is done automatically for the restApi.latestDeployment deployment.

Example:

# production stage
prod_log_group = logs.LogGroup(self, "PrdLogs")
api = apigateway.RestApi(self, "books",
    deploy_options=apigateway.StageOptions(
        access_log_destination=apigateway.LogGroupLogDestination(prod_log_group),
        access_log_format=apigateway.AccessLogFormat.json_with_standard_fields()
    )
)
deployment = apigateway.Deployment(self, "Deployment", api=api)

# development stage
dev_log_group = logs.LogGroup(self, "DevLogs")
apigateway.Stage(self, "dev",
    deployment=deployment,
    access_log_destination=apigateway.LogGroupLogDestination(dev_log_group),
    access_log_format=apigateway.AccessLogFormat.json_with_standard_fields(
        caller=False,
        http_method=True,
        ip=True,
        protocol=True,
        request_time=True,
        resource_path=True,
        response_length=True,
        status=True,
        user=True
    )
)

Parameters:

scope (Construct) –
id (str) –
api (IRestApi) – The Rest API to deploy.
description (Optional[str]) – A description of the purpose of the API Gateway deployment. Default: - No description.
retain_deployments (Optional[bool]) – When an API Gateway model is updated, a new deployment will automatically be created. If this is true, the old API Gateway Deployment resource will not be deleted. This will allow manually reverting back to a previous deployment in case for example Default: false
stage_name (Optional[str]) – The name of the stage the API Gateway deployment deploys to. Default: - No stage name. If the stageName property is set but a stage with the corresponding name does not exist, a new stage resource will be created with the provided stage name.

Methods

add_to_logical_id(data)

Adds a component to the hash that determines this Deployment resource’s logical ID.

This should be called by constructs of the API Gateway model that want to invalidate the deployment when their settings change. The component will be resolve()ed during synthesis so tokens are welcome.

Parameters:

data (Any) –

Return type:

None

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

api

deployment_id

true

Type:: attribute

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.

node: The tree node.

stack: The stack in which this resource is defined.

stage_name: The stage of the API gateway deployment.

Static Methods

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
