如何在 Jenkins 中将 Docker 镜像推送到 ECR？

Question

我正在与詹金斯一起工作。我正在尝试将图像推送到ECR。我正在使用本地 Docker 来构建图像。

下面是我的 Jenkins 文件：

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....'
            }
        }
    }
}

在上面的代码中，我能够构建和创建图像。在第二阶段，我面临着问题。我收到以下错误：

$ docker login -u AWS -p ******** https://536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository

有人可以帮我解决这个问题吗？任何帮助将不胜感激。
谢谢。

docker.io 的默认存储库是 hardcode 是：docker.io/library/

因此，对于 AWS ECR 存储库，您应该：

docker build -t test-repository .

docker 标签 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

确保test-repository repo 已在 ECR 上创建。
