    CodePipeline

    Overview

    This is the CodePipeline API Reference. This guide provides descriptions of the actions and data types for CodePipeline. Some functionality for your pipeline can only be configured through the API. For more information, see the CodePipeline User Guide.

    You can use the CodePipeline API to work with pipelines, stages, actions, and transitions.

    Pipelines are models of automated release processes. Each pipeline is uniquely named, and consists of stages, actions, and transitions.

    You can work with pipelines by calling:

    • CreatePipeline, which creates a uniquely named pipeline.

    • DeletePipeline, which deletes the specified pipeline.

    • GetPipeline, which returns information about the pipeline structure and pipeline metadata, including the pipeline Amazon Resource Name (ARN).

    • GetPipelineExecution, which returns information about a specific execution of a pipeline.

    • GetPipelineState, which returns information about the current state of the stages and actions of a pipeline.

    • ListActionExecutions, which returns action-level details for past executions. The details include full stage and action-level details, including individual action duration, status, any errors that occurred during the execution, and input and output artifact location details.

    • ListPipelines, which gets a summary of all of the pipelines associated with your account.

    • ListPipelineExecutions, which gets a summary of the most recent executions for a pipeline.

    • StartPipelineExecution, which runs the most recent revision of an artifact through the pipeline.

    • StopPipelineExecution, which stops the specified pipeline execution from continuing through the pipeline.

    • UpdatePipeline, which updates a pipeline with edits or changes to the structure of the pipeline.

    Pipelines include stages. Each stage contains one or more actions that must complete before the next stage begins. A stage results in success or failure. If a stage fails, the pipeline stops at that stage and remains stopped until either a new version of an artifact appears in the source location, or a user takes action to rerun the most recent artifact through the pipeline. You can call GetPipelineState, which displays the status of a pipeline, including the status of stages in the pipeline, or GetPipeline, which returns the entire structure of the pipeline, including the stages of that pipeline. For more information about the structure of stages and actions, see CodePipeline Pipeline Structure Reference.

    Pipeline stages include actions that are categorized into categories such as source or build actions performed in a stage of a pipeline. For example, you can use a source action to import artifacts into a pipeline from a source such as Amazon S3. Like stages, you do not work with actions directly in most cases, but you do define and interact with actions when working with pipeline operations such as CreatePipeline and GetPipelineState. Valid action categories are:

    • Source

    • Build

    • Test

    • Deploy

    • Approval

    • Invoke

    Pipelines also include transitions, which allow the transition of artifacts from one stage to the next in a pipeline after the actions in one stage complete.

    You can work with transitions by calling:

    Using the API to integrate with CodePipeline

    For third-party integrators or developers who want to create their own integrations with CodePipeline, the expected sequence varies from the standard API user. To integrate with CodePipeline, developers need to work with the following items:

    Jobs, which are instances of an action. For example, a job for a source action might import a revision of an artifact from a source.

    You can work with jobs by calling:

    Third party jobs, which are instances of an action created by a partner action and integrated into CodePipeline. Partner actions are created by members of the Amazon Web Services Partner Network.

    You can work with third party jobs by calling:

    • Method Detail

      • setEndpoint

        @Deprecated
        void setEndpoint(String endpoint)
        Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
        Overrides the default endpoint for this client ("https://codepipeline.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

        Callers can pass in just the endpoint (ex: "codepipeline.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://codepipeline.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

        For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint

        This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

        Parameters:
        endpoint - The endpoint (ex: "codepipeline.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://codepipeline.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

      • retryStageExecution

        RetryStageExecutionResult retryStageExecution(RetryStageExecutionRequest retryStageExecutionRequest)

        You can retry a stage that has failed without having to run a pipeline again from the beginning. You do this by either retrying the failed actions in a stage or by retrying all actions in the stage starting from the first action in the stage. When you retry the failed actions in a stage, all actions that are still in progress continue working, and failed actions are triggered again. When you retry a failed stage from the first action in the stage, the stage cannot have any actions in progress. Before a stage can be retried, it must either have all actions failed or some actions failed and some succeeded.

        Parameters:
        retryStageExecutionRequest - Represents the input of a RetryStageExecution action.
        Returns:
        Result of the RetryStageExecution operation returned by the service.
        Throws:
        ValidationException - The validation was specified in an invalid format.
        ConflictException - Your request cannot be handled because the pipeline is busy handling ongoing activities. Try again later.
        PipelineNotFoundException - The pipeline was specified in an invalid format or cannot be found.
        StageNotFoundException - The stage was specified in an invalid format or cannot be found.
        StageNotRetryableException - Unable to retry. The pipeline structure or stage state might have changed while actions awaited retry, or the stage contains no failed actions.
        NotLatestPipelineExecutionException - The stage has failed in a later run of the pipeline and the pipelineExecutionId associated with the request is out of date.
        ConcurrentPipelineExecutionsLimitExceededException - The pipeline has reached the limit for concurrent pipeline executions.

      • shutdown

        void shutdown()
        Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
      • getCachedResponseMetadata

        ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
        Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

        Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

        Parameters:
        request - The originally executed request.
        Returns:
        The response metadata for the specified request, or null if none is available.
