AWS CDK EcsDeployAction 更新现有 Fargate 服务

Question

I'm deployng Fargate services through AWS CDK with ease.

Now I need to update a service, for instance a task image.
I 'm trying to accomplish this by using @aws-cdk/aws-codepipeline and the action EcsDeployAction

I'm trying to import and update an existing (previously deployed) fargate service, like this:

const pipeline = new codepipeline.Pipeline(this, 'MyPipeline')

// import an existing fargate service
const fargateService = ecs.FargateService.fromFargateServiceArn(
  this,
  "FargateService",
  "MyFargateServiceARN"
);

// Deploy a new version according to what 
const sourceStage = this.pipeline.addStage({
  stageName: 'Deploy',
  actions: [
    new codepipeline_actions.EcsDeployAction({
      actionName: "ECS-Service",
      service: fargateService,       <--- here the typescript error
      input: ...
    })
  ]
})

But it does not seem correct because I get a typescript error:

Property 'cluster' is missing in type 'IFargateService' but required in type 'IBaseService'

Any idea?

Answer 1

There's a type mismatch. EcsDeployActionProps expects the service prop to be of the type IBaseService . But it's getting an incompatible IFargateService type from fromFargateServiceArn .

Luckily, the related static fromFargateServiceAttributes(scope, id, attrs) returns the compatible type IBaseService you are looking for.
