docker+gitlab+gitlab-runner部署详解

 $ uname -r

$ sudo yum update

$ sudo yum remove docker docker-common docker-selinux docker-engine

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

$ yum list docker-ce --showduplicates | sort -r

$ sudo yum install docker-ce #由于repo中默认只开启stable仓库，故这里安装的是最新稳定版17.12.0$ sudo yum install  # 例如：sudo yum install docker-ce-17.12.0.ce
如果错误：
问题: package docker-ce-3:19.03.8-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed解决：https://www.cnblogs.com/suanmiaoup/p/12772140.html输入：yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm再输入：yum install docker-ce docker-ce-cli containerd.io

git init #如果还没有初始化
git add . #把项目都添加进去
git commit -m "init" 提交到git
git remote add origin git@gitlab.domain.com:1022/root/test.git #注意端口为1022 这个是上面运行gitlab是指定的，执行一次就行了
git push -u origin master #推送到服务器gitlab上
