Docker REST API 未绑定到 Jenkins 的端口

Question

我正在使用： docker 版本：1.11.1，构建 5604cbe。我在 /etc/default/docker 中进行了如下设置，为 jenkins 用户组配置 docker 的 REST API :

    # Use DOCKER_OPTS to modify the daemon startup options.
    #DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

    DOCKER_OPTS="G- jenkins -H unix://var/run/docker.sock -H tcp://0.0.0.0:9090"

    export DOCKER_HOST="tcp://0.0.0.0:9090"

ps- 我也试过 127.0.0.1

然后我做了sudo service docker restart

命令$ ps aux|grep docker返回：

root     12385  0.0  0.2 421840 36016 ?        Ssl  19:21   0:00 /usr/bin/docker daemon -H fd://
root     12391  0.0  0.0 294652 12188 ?        Ssl  19:21   0:00 docker-containerd -l /var/run/docker/libcontainerd/docker-containerd.sock --runtime docker-runc
root     12654  0.0  0.0  21296  1028 pts/1    S+   19:28   0:00 grep --color=auto docker

似乎 REST API 没有绑定到 port:9090.

然后我使用 Jenkins Docker 构建步骤插件 连接 docker REST API。它 returns 以下 :

Building in workspace /var/lib/jenkins/jobs/Telco_automated_build/workspace

    at hudson.tasks.BuildStepMonitor.perform(BuildStepMonitor.java:20)

在 jenkins 全局设置 当我点击 test-connection 它 returns:

Something went wrong, cannot connect to http://127.0.0.1:9090/, cause: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:9090 [/127.0.0.1] failed: Connection refused

PS- 我在更改全局设置后重新启动了 Jenkins 服务器。

任何帮助，我错过了什么？

Ubuntu 我相信 16.04 现在使用 systemd。在这种情况下，docker daemon 参数未使用 /etc/default/docker 设置。您可以在 $ ps aux|grep docker 的输出中看到它们没有被拾取。

相反，您需要 follow the instructions 在基于 systemd 的设置中设置守护进程参数。
