超！超！超简单，Linux安装Docker

1、安装依赖
yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

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

 

2、设置yum源

#中央仓库
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
#阿里仓库
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

 

3、查看仓库中所有Docker版本

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

 

4、安装Docker

# 默认安装
sudo yum -y install docker-ce

 

5、启动, 加入开机启动

#启动
sudo systemctl start docker
#加入开机启动
sudo systemctl enable docker
#重启
sudo systemctl restart  docker
#关闭
sudo systemctl stop docker

 

6、验证是否安装成功

sudo docker version

 

7、添加GitLab Runner官方仓库

curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh | sudo bash

 

8、安装最新版本GitLab Runner

sudo yum install gitlab-runner

 

9、给 gitlab-runner 执行sudo权限

## Allow root to run any commands anywhere 
root    ALL=(ALL)       ALL
gitlab-runner ALL=(ALL)       NOPASSWD:ALL
