PipelineBase

class aws_cdk.pipelines.PipelineBase(scope, id, *, synth)

Bases: Construct

A generic CDK Pipelines pipeline.

Different deployment systems will provide subclasses of Pipeline that generate the deployment infrastructure necessary to deploy CDK apps, specific to that system.

This library comes with the CodePipeline class, which uses AWS CodePipeline to deploy CDK apps.

The actual pipeline infrastructure is constructed (by invoking the engine) when buildPipeline() is called, or when app.synth() is called (whichever happens first).

Parameters:
  • scope (Construct) –

  • id (str) –

  • synth (IFileSetProducer) – The build step that produces the CDK Cloud Assembly. The primary output of this step needs to be the cdk.out directory generated by the cdk synth command. If you use a ShellStep here and you don’t configure an output directory, the output directory will automatically be assumed to be cdk.out.

Methods

add_stage(stage, *, post=None, pre=None, stack_steps=None)

Deploy a single Stage by itself.

Add a Stage to the pipeline, to be deployed in sequence with other Stages added to the pipeline. All Stacks in the stage will be deployed in an order automatically determined by their relative dependencies.

Parameters:
  • stage (Stage) –

  • post (Optional[Sequence[Step]]) – Additional steps to run after all of the stacks in the stage. Default: - No additional steps

  • pre (Optional[Sequence[Step]]) – Additional steps to run before any of the stacks in the stage. Default: - No additional steps

  • stack_steps (Optional[Sequence[Union[StackSteps, Dict[str, Any]]]]) – Instructions for stack level steps. Default: - No additional instructions

Return type:

StageDeployment

add_wave(id, *, post=None, pre=None)

Add a Wave to the pipeline, for deploying multiple Stages in parallel.

Use the return object of this method to deploy multiple stages in parallel.

Example:

# pipeline: pipelines.CodePipeline


wave = pipeline.add_wave("MyWave")
wave.add_stage(MyApplicationStage(self, "Stage1"))
wave.add_stage(MyApplicationStage(self, "Stage2"))
Parameters:
  • id (str) –

  • post (Optional[Sequence[Step]]) – Additional steps to run after all of the stages in the wave. Default: - No additional steps

  • pre (Optional[Sequence[Step]]) – Additional steps to run before any of the stages in the wave. Default: - No additional steps

Return type:

Wave

build_pipeline()

Send the current pipeline definition to the engine, and construct the pipeline.

It is not possible to modify the pipeline after calling this method.

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

cloud_assembly_file_set

The FileSet tha contains the cloud assembly.

This is the primary output of the synth step.

node

The tree node.

synth

The build step that produces the CDK Cloud Assembly.

waves

The waves in this pipeline.

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_pipeline(x)

Return whether the given object extends PipelineBase.

We do attribute detection since we can’t reliably use ‘instanceof’.

Parameters:

x (Any) –

Return type:

bool
