jenkins - Jenkins 中的远程docker主机的docker exec错误

Question

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

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 : nothing to print

预期的结果是在Jenkins控制台日志中打印'aaa'。

远程Docker版本为:

Client:
 Version:      1.12.5
 API version:  1.24
 Go version:   go1.6.4
 Git commit:   7392c3b

Answer 1

试试吧

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

这样，您至少可以检查以下内容:

docker 正在工作

容器development-taxpayer-server-131-1正在运行

然后，考虑 docker exec syntax，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?”显示相同的回声，没有任何选择:

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