1、安装docker

sudo apt-get remove docker docker-engine docker-ce docker.io
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
 sudo apt-get update
 sudo apt-get install -y docker-ce
 sudo docker run hello-world #测试docker是否安装成功

配置docker为国内镜像，提高下载速度
新建 /etc/docker/daemon.json并添加：

{
"registry-mirrors": ["https://registry.docker-cn.com"]
}

2、安装gerrit镜像

docker pull openfrontier/gerrit

3、启动镜像

sudo docker run -d -p 8080:8080 -p 29418:29418 openfrontier/gerrit

进入容器

docker exec -it 67577a75c48e /bin/bash
