使用jenkins+marathon+docker完成自动化部署

1.前置条件

Docker开启TCP端口

开启docker apiserver的2375管理端口，本示例在CentOS7环境下。编辑docker.service文件，修改ExecStart参数，添加-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

vim ./usr/lib/systemd/system/docker.service

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always
