Stage¶

class aws_cdk.core.Stage(scope, id, *, env=None, outdir=None)¶

Bases: aws_cdk.core.Construct

An abstract application modeling unit consisting of Stacks that should be deployed together.

Derive a subclass of Stage and use it to model a single instance of your application.

You can then instantiate your subclass multiple times to model multiple copies of your application which should be be deployed to different environments.

__init__(scope, id, *, env=None, outdir=None)¶

Parameters

scope (Construct) –
id (str) –
env (Optional[Environment]) – Default AWS environment (account/region) for Stack``s in this ``Stage. Stacks defined inside this Stage with either region or account missing from its env will use the corresponding field given here. If either region or account``is is not configured for ``Stack (either on the Stack itself or on the containing Stage), the Stack will be environment-agnostic. Environment-agnostic stacks can be deployed to any environment, may not be able to take advantage of all features of the CDK. For example, they will not be able to use environmental context lookups, will not automatically translate Service Principals to the right format based on the environment’s AWS partition, and other such enhancements. Default: - The environments should be configured on the ``Stack``s.
outdir (Optional[str]) – The output directory into which to emit synthesized artifacts. Can only be specified if this stage is the root stage (the app). If this is specified and this stage is nested within another stage, an error will be thrown. Default: - for nested stages, outdir will be determined as a relative directory to the outdir of the app. For apps, if outdir is not specified, a temporary directory will be created.

Return type

None

Methods

synth(*, force=None, skip_validation=None)¶

Synthesize this stage into a cloud assembly.

Once an assembly has been synthesized, it cannot be modified. Subsequent calls will return the same assembly.

Parameters

force (Optional[bool]) – Force a re-synth, even if the stage has already been synthesized. This is used by tests to allow for incremental verification of the output. Do not use in production. Default: false
skip_validation (Optional[bool]) – Should we skip construct validation. Default: - false

Return type

CloudAssembly

to_string()¶

Returns a string representation of this construct.

Return type: str

Attributes

account¶

The default account for all resources defined within this stage.

stability :stability: experimental

Return type: Optional[str]

artifact_id¶

Artifact ID of the assembly if it is a nested stage. The root stage (app) will return an empty string.

Derived from the construct path.

stability :stability: experimental

Return type: str

node¶

The construct tree node associated with this construct.

Return type: ConstructNode

outdir¶

The cloud assembly output directory.

Return type: str

parent_stage¶

The parent stage or undefined if this is the app.

stability :stability: experimental

Return type: Optional[Stage]

region¶

The default region for all resources defined within this stage.

stability :stability: experimental

Return type: Optional[str]

stage_name¶

The name of the stage.

Based on names of the parent stages separated by hypens.

stability :stability: experimental

Return type: str

Static Methods
