如何使用 kuberntes 代理构建 docker 镜像？

Question

下面是我在kubernetes插件中设置的配置。

我的詹金斯管道。

pipeline {
    agent {
        kubernetes {
            label 'my-docker-build'
            defaultContainer 'jnlp'
            yaml """
            apiVersion: v1
            kind: Pod
            metadata:
              labels:
                app: my-docker-build
            spec:
              containers:
              - name: docker
                image: docker:latest
                command: ["cat"]
                tty: true
              volumes:
              - name: docker-sock
                hostPath:
                  path: /var/run/docker.sock
              - name: my-repo
                gitRepo:
                  repository: https://github.com/my/repo.git
            """
        }
    }
    stages {
        stage('Build Docker Image') {
            steps {
                sh 'hostname'
                sh 'sleep 50'
                sh 'docker --version'
                sh 'docker build -t my-docker-image:latest .'
            }
        }
        stage('Push Docker Image') {
            steps {
                sh 'docker push my-docker-image:latest'
            }
        }
    }
}

我收到的错误：

我做了一些研究，并改变了管道步骤这部分。

stage('Build Docker Image') {
            steps {
                container('docker') {
                sh 'hostname'
                sh 'sleep 50'
                sh 'docker --version'
                sh 'docker build -t my-docker-image:latest .'
                }}}

但仍然出现此错误。
