amazon-web-services - 在 AWS CDK 中，应如何将 CodeStarConnectionsSourceAction 用作 CodePipeline 的输入？

Question

我正在尝试建立一个从 Github 获取代码并部署它的管道(Lambda、DynamoDB 等，使用 CDK)。我目前正在尝试使其与 CodeStarConnectionsSourceAction 一起使用，但我的代码因以下错误而失败:

  [Example4BePipeline/Example4BePipeline/Pipeline] Action Synth in stage Build: first stage may only contain Source actions
  [Example4BePipeline/Example4BePipeline/Pipeline] Action 'Synth' is using input Artifact 'Sources', which is not being produced in this pipeline

产生该错误的代码是:

import * as cdk from "aws-cdk-lib"
import {Construct} from "constructs"
import {Example4BeDeployStage} from "./example4-be-deploy-stage"
import {CodeBuildStep, CodePipeline, CodePipelineFileSet} from "aws-cdk-lib/pipelines"
import {CodeStarConnectionsSourceAction} from "aws-cdk-lib/aws-codepipeline-actions";
import {Artifact} from "aws-cdk-lib/aws-codepipeline";

export class PipelineStack extends cdk.Stack {
    constructor(scope: Construct, id: string, props?: cdk.StackProps) {
        super(scope, id, props)

        const sourceOutput = new Artifact("Sources");
        const sourceAction = new CodeStarConnectionsSourceAction({
            actionName: "Github",
            owner: "username",
            repo: "example4-be",
            output: sourceOutput,
            connectionArn: "arn:aws:codestar-connections:us-east-1:....:connection/...."
        })
        const pipeline = new CodePipeline(this, "Example4BePipeline", {
            pipelineName: "Example4BePipeline",
            synth: new CodeBuildStep("Synth", {
                    input: CodePipelineFileSet.fromArtifact(sourceOutput),
                    installCommands: [
                        "npm install -g aws-cdk"
                    ],
                    commands: [
                        "npm ci",
                        "npm run build",
                        "npx cdk synth"
                    ]
                }
            ),
            selfMutation: false // TODO: remove before committing.
        })
    }
}

我在这里做错了什么？

我明白了，这是工作代码，更短/简洁:

import * as cdk from "aws-cdk-lib"
import {Construct} from "constructs"
import {Example4BeDeployStage} from "./example4-be-deploy-stage"
import {CodeBuildStep, CodePipeline, CodePipelineSource} from "aws-cdk-lib/pipelines"

export class PipelineStack extends cdk.Stack {
    constructor(scope: Construct, id: string, props?: cdk.StackProps) {
        super(scope, id, props)

        const pipeline = new CodePipeline(this, "Example4BePipeline", {
            pipelineName: "Example4BePipeline",
            synth: new CodeBuildStep("Synth", {
                    input: CodePipelineSource.connection("username/example4-be", "main", {
                        connectionArn: "arn:aws:codestar-connections:us-east-1:....:connection/....",
                    }),
                    installCommands: [
                        "npm install -g aws-cdk"
                    ],
                    commands: [
                        "npm ci",
                        "npm run build",
                        "npx cdk synth"
                    ]
                }
            ),
            selfMutation: false // TODO: remove before committing.
        })
    }
}
