### 安装docker ###

[Ubuntu 详细安装 https://blog.csdn.net/weixin\_44953227/article/details/109470722][Ubuntu _ https_blog.csdn.net_weixin_44953227_article_details_109470722]

> 这里以 CentOS 为例

官方文档：[https://docs.docker.com/engine/install/centos/][https_docs.docker.com_engine_install_centos]

# 1. 卸载旧版docker
    sudo yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-engine
    
    # 2. 需要的安装包
    sudo yum install -y yum-utils
    
    # 3. 设置镜像仓库
    # 这个是官方的, 不推荐
    #sudo yum-config-manager \
    # --add-repo \
    # https://download.docker.com/linux/centos/docker-ce.repo # 默认是国外的贼慢, 不推荐
    
    # 推荐使用 阿里云的
    sudo yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 	# 推荐使用阿里云, 贼快
    
    # 更新yum软件包索引
    sudo yum makecache fast
    
    # 4. 安装docker相关的 docker-ce 社区版 ee企业版
    sudo yum install -y docker-ce docker-ce-cli containerd.io
    
    # 5. 启动docker
    sudo systemctl start docker
    
    # 6. 使用docker version查看是否安装成功
    docker version
    
    # 7. hello world
    sudo docker run hello-world

### 卸载docker ###

# 1. 停止docker服务
    systemctl stop docker
    
    # 2. 卸载镜像
    sudo yum remove docker-ce docker-ce-cli containerd.io
    
    # 3. 删除目录
    sudo rm -rf /var/lib/docker
    sudo rm -rf /var/lib/containerd
    
    # 3. /var/lib/docker docker的默认工作路径
