我正试图用docker命令通过jenkins执行octobercms迁移，但jenkins控制台中有下一个错误：

+ docker exec -u jenkins dockerfilemaster_app_1 php artisan october:up
Migrating application and plugins...

[Illuminate\Database\QueryException]

information_s  
chema.tables where table_schema = databasename and table_name = 
migrations)

[PDOException]                             
SQLSTATE[HY000] [2002] Connection refused

这是我正在使用的声明性jenkinsfile（“ping”命令是为了确保数据库是可访问的）：

pipeline {
    agent any
        stages {
            stage('Composer') {
                steps {
                    script {
                        sh '''
                            chmod -R 777 storage
                            composer install
                            docker-compose up --build -d
                            '''
                    }
                }
            }

            stage('Docker') {
                steps {
                    script {
                        sh '''
                            docker exec dockerfilemaster_app_1 useradd jenkins
                            docker exec -u jenkins dockerfilemaster_app_1 ping -c 2 database
                            docker exec -u jenkins dockerfilemaster_app_1 php artisan october:up
                            docker exec -u jenkins dockerfilemaster_app_1 php artisan october:down --force
                            '''
                    }
                }
            }
        }
    post {
        always {
            sh '''
                docker-compose down
                '''
        }
    }
}

但是如果我用ssh连接到jenkins服务器，并执行相同的脚本，它就可以工作了：

docker-compose up --build -d
docker exec dockerfilemaster_app_1 useradd jenkins
docker exec -u jenkins dockerfilemaster_app_1 php artisan october:up

数据库配置：

'mysql' => [
            'driver'    => 'mysql',
            'host' => env('DB_HOST', 'database'),
            'port' => env('DB_PORT', 3306),
            'database' => env('DB_DATABASE', 'databasename'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', 'secret'),
            'charset'   => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix'    => '',
        ],

docker-compose.yml文件：

version: '2'
services:
    web:
        build:
            context: ./
            dockerfile: web.docker
        volumes:
            - ./:/var/www/public
        ports:
            - "8081:80"
        links:
            - app
    app:
        build:
            context: ./
            dockerfile: app.docker
        volumes:
            - ./:/var/www
        links:
            - database
        environment:
            - "DB_PORT=3306"
            - "DB_HOST=database"
    database:
        image: mysql:5.6
        environment:
            - "MYSQL_ROOT_PASSWORD=secret"
            - "MYSQL_DATABASE=databasename"
        ports:
            - "3306:3306"

我不明白为什么我在与ssh连接的服务器上执行这个脚本会起作用，但是如果jenkins执行相同的脚本就不起作用了。
这是整个jenkins控制台输出：

在安装应用程序的同时 DB 示例无法启动，因此我们可以添加 depends_on . 在这种环境下，数据库总是会产生问题。

version: '2'
services:
    web:
        build:
            context: ./
            dockerfile: web.docker
        volumes:
            - ./:/var/www/public
        ports:
            - "8081:80"
        links:
            - app
        depends_on:     <= THIS       
            - "app"     <= N THIS
    app:
        build:
            context: ./
            dockerfile: app.docker
        volumes:
            - ./:/var/www
        links:
            - database
        depends_on:          <= THIS       
            - "database"     <= N THIS
        environment:
            - "DB_PORT=3306"
            - "DB_HOST=database"
    database:
        image: mysql:5.6
        environment:
            - "MYSQL_ROOT_PASSWORD=secret"
            - "MYSQL_DATABASE=databasename"
        ports:
            - "3306:3306"

也许它能解决你的问题。如果 NOT 然后您需要检查以下参考资料中建议的工具是否会对您有所帮助。正如他们提到的 DB 在docker环境中产生问题。
您可以从这里查看参考资料：https://docs.docker.com/compose/startup-order/

添加“sleep”命令对我有效。似乎在第二阶段（名为“docker”的阶段）开始时docker仍未构建。我以为当前一个阶段完全结束时，这个阶段就开始了。这是最终的Jenkins档案：

pipeline {
    agent any
        stages {
            stage('Docker') {
                steps {
                    script {
                        sh '''
                            chmod -R 777 storage
                            docker-compose up --build -d
                            sleep 30
                            docker exec dockerfilemaster_app_1 useradd jenkins
                            docker exec dockerfilemaster_app_1 chmod -R 777 /var/www
                            docker exec -u jenkins dockerfilemaster_app_1 composer install
                            docker exec -u jenkins dockerfilemaster_app_1 php artisan october:up
                            docker exec -u jenkins dockerfilemaster_app_1 php artisan october:down --force
                            '''
                    }
                }
            }
        }
    post {
        always {
            sh '''
                docker-compose down
                '''
        }
    }
}

我将“docker compose up”命令与其他docker命令放在一起，因为将该命令放在另一个阶段没有帮助。
