Jenkins pipeline alpine agent "apk update ERROR: Unable to lock database: Permission denied"

Question

我使用Alpine docker镜像作为Jenkins管道代理，但我一直得到权限拒绝的错误，当运行 apk update 或 apk add package. 我在运行Ubuntu图像时也看到类似的错误。apt update 或 apt install

这是我的Jenkins文件。

pipeline {
    agent none
    stages {
        stage('Initialization') {
            agent any
            steps {
                checkout scm
            }
        }

        stage('Git Clone') {
            agent { docker { image 'alpine:3.12.0' } }
            steps {
                sh '''
                    apk update;
                    apk add --no-cache git;
                    apk add --no-cache openssh;
                    git -v;
                '''
            }
        }
    }
}

这是Jenkins的输出。

谁能帮我找出问题所在？

Answer 1

请像这样修改Jenkins pipeline的docker标签。

docker { 
image 'alpine:3.12.0' 
args '-u root:root'
 } 

Answer 2

我相信问题是Jenkins用非root用户运行容器，因此出现了 Permission denied 错误。

试着改变你的管道，像这样。

agent {
    docker {
            image 'alpine:3.12.0'
            args '-u root'
        }
    }
