如何将Docker镜像推送到Jenkins中的ECR？

Question

I am working with Jenkins. I am trying to push image to ECR . I am using local Docker to build the images.

Below is my Jenkins file:

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                bat  'docker build -t sampleapp -f SampleApp/Dockerfile .'
            }
        }
        stage('Push image') {
         steps {
           withDockerRegistry([url: "https://536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository",credentialsId: "ecr:ap-southeast-2:demo-ecr-credentials"]) {
           bat 'docker push sampleapp:latest'
               }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying....'
            }
        }
    }
}

In the above code, I am able to build and create an image. In the second stage, I am facing the issues. I am getting the below error:

 $ docker login -u AWS -p ******** https://536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository WARNING. Using --password via the CLI is insecure. Use --password-stdin: Login Succeeded C:\Program Files (x86)\Jenkins\workspace\SampleAppPipeLine>docker push sampleapp.latest The push refers to repository [docker:io/library/sampleapp] a160522d6d0e: Preparing 2e2c2606bd45: Preparing 9b0a482c69b1: Preparing 995a0cc6a5f6: Preparing c1b55dcb46c2: Preparing cf5b3c6798f7: Preparing cf5b3c6798f7: Waiting denied: requested access to the resource is denied

Can someone help me to fix this issue? Any help would be appreciated.
Thanks.

Default repository of docker.io is being hardcode is: docker.io/library/

So for AWS ECR repo, you should:

docker build -t test-repository .

docker tag test-repository:latest 536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository:latest

docker push 536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository:latest

Make sure test-repository repo is already create on ECR.
