5、在linux部署docker

一、安装docker

# 卸载原始docker
$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

# 安装docker依赖
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 设置docker的yum源
$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

# 安装最新版的docker
$ sudo yum install docker-ce docker-ce-cli containerd.io

# 启动docker
$ sudo systemctl enable docker
$ sudo systemctl start docker

# 关闭docker
$ sudo systemctl stop docker

# 测试docker安装
$ sudo docker run hello-world

二、配置镜像

# 访问阿里云登录自己账号查看docker镜像加速服务
sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://xxxx.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload

sudo systemctl restart docker

# 验证docker的镜像加速是否生效
sudo docker info
