docker exec在Jenkins

Question

我使用Jenkins + Pipeline + DockerPlugin来构建和运行带有远程主机的docker容器，当执行命令时如下：

docker.withServer("tcp://192.168.1.122:2375",'') {
    def wait_results = sh(script: "docker exec -t development-taxpayer-server-131-1 echo aaa", returnStdout: true)
    print wait_results
}

  

wait_results：无需打印

预期结果是在Jenkins控制台日志中打印'aaa'。

远程泊坞广告版本是：

Client:

Answer 1

尝试改为

def wait_results = sh(script: "docker ps -a", returnStdout: true)

这样你至少可以检查：

• docker正在运作
• 容器development-taxpayer-server-131-1正在运行

然后，考虑docker exec syntax，请尝试-it：

def wait_results = sh(script: "docker exec -it development-taxpayer-server-131-1 echo aaa", returnStdout: true)

注意：“How to run a command on an already existing docker container?”显示相同的回显没有任何选项：

docker exec development-taxpayer-server-131-1 echo aaa
