Question

当前，我正在访问一个外部数据库以在管道中执行单元测试。我想通过在管道中实施本地测试来增加构建的运行时间。

我正在尝试使用this格式。

docker.image('mysql:5.6').withRun(' -e "MYSQL_ROOT_PASSWORD=pass" ') { c ->

    sh('docker ps -l')

    docker.image('mysql:5.6').inside(" --link ${c.id}:db ") {

        /* Wait until mysql service is up */
        sh ("while ! mysqladmin ping -hdb:3306 -ppass; do sleep 1; done")

    }

    docker.image(imageName).inside(" --link ${c.id}:db ") {
        /*
        * Run some tests which require MySQL, and assume that it is
        * available on the host name `db`
        */
        sh("echo test")
        //run some tests        
    }
}

代码未到达第二张图片。由于can't connect to the host 'db'，它之前会出错。输出如下：

我尝试从:3306删除mysqladmin

我尝试将-p 3306:3306添加到主容器和sidecar mysql容器中。

我尝试将-u 0添加到两个容器中。

Docker Version 18.09

Jenkins Version 2.164

K8s Version 1.11

不确定下一步该怎么做。有建议吗？

Answer 1

不确定这里出了什么问题，但是最后使用withRun作为第一辆小车，并使用docker exec进行ping操作。这样就解决了。

无法在我的Jenkins管道中链接两个“ sidecar”容器
