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

Question

我正在使用 Alpine docker 图像作为 Jenkins 管道代理，但在运行 apk update 或 apk add package 期间我一直收到权限被拒绝的错误。我在 Ubuntu 图片上也看到了类似的错误，而运行 apt update 或 apt install

这是我的 Jenkinsfile：

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：

+ docker inspect -f . alpine:3.12.0

谁能帮我解决这个问题？

Answer 1

请像这样修改 Jenkins 管道中的 docker 标记：

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

Answer 2

我认为问题是 Jenkins 是运行非 root 用户的容器，因此 Permission denied 错误。

尝试像这样更改您的管道：

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