Push to ECR from Jenkins pipeline

Question

I have Jenkins server on-preminse. I have Jenkins file which create Docker image now i want to push that image to AWS ECR.Do i have to create a special IAM user and provide its access and secret access keys ? Or what will be the best way to do this.

I found below on internet

  withAWS(role:'Jenkins', roleAccount:'XXXX216610',duration: 900, roleSessionName: 'jenkinssession')
  sh ' eval \$(aws ecr get-login --no-include-email --region us-east-2) '

But as my jenkins server is onprem how role will work ?

Answer 1

Instead of eval, you now can use the Jenkins ‘amazon-ecr’ plugin from https://plugins.jenkins.io/amazon-ecr/ for ECR deployments.

pipeline {
  environment {
    registry = '1111111111111.dkr.ecr.eu-central-1.amazonaws.com/myRepo'
    registryCredential = 'ID_OF_MY_AWS_JENKINS_CREDENTIAL'
    dockerImage = ''
  }
  agent any
  stages {
    stage('Building image') {
      steps{
        script {
          dockerImage = docker.build registry + ":$BUILD_NUMBER"
        }
      }
    }
    stage('Deploy image') {
        steps{
            script{
                docker.withRegistry("https://" + registry, "ecr:eu-central-1:" + registryCredential) {
                    dockerImage.push()
                }
            }
        }
    }
  }
}
