使用docker api
前提: 系统centos 7 docker version 1.10.3 使用systemd启动docker 访问方式: 修改/usr/lib/systemd/system/docker.service中的ExecStart，添加host " -H tcp://0.0.0.0:1234 " ExecStart=/usr/bin/docker daemon $DOCKER_OPTS -H tcp://0.0.0.0:1234执行systemctl --system daemon-reload, 将docker守护进程绑定到网络接口1234上。 (我机器执行上述命令没起作用，我就重启了docker : systemctl restart docker.service) 这时候会看到1234端口被docker进程绑定了。 [root@node888 system]# ss -anp | grep 1234 tcp LISTEN 0 128 :::1234 :::* users:(("docker",8694,6)) 查看docker信息，验证绑定情况 docker -H localhost:1234 info 可以看到 Containers: 49 Running: 1 Paused: 0 Stopped: 48 Images: 6 Server Version: 1.10.3 Storage Driver: devicemapper Pool Name: docker-253:0-202045413-pool Pool Blocksize: 65.54 kB Base Device Size: 10.74 GB Backing Filesystem: xfs Data file: /dev/loop0 Metadata file: /dev/loop1 Data Space Used: 4.555 GB Data Space Total: 107.4 GB Data Space Available: 2.347 GB Metadata Space Used: 10.02 MB Metadata Space Total: 2.147 GB Metadata Space Available: 2.137 GB Udev Sync Supported: false Deferred Removal Enabled: false Deferred Deletion Enabled: false Deferred Deleted Device Count: 0 Data loop file: /var/lib/docker/devicemapper/devicemapper/data WARNING: Usage of loopback devices is strongly discouraged for production use.
