安装docker工具与使用

docker安装

要采用国内源：

https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/ 
https://mirrors.aliyun.com/docker-ce/linux/ubuntu

---

1. 删除旧版本docker

sudo apt-get remove docker docker-engine docker.io containerd runc

2. 更新apt包索引，输入一下命令:apt update
3. 安装apt依赖包，用于通过HTTPS来获取仓库

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

4. 添加Docker的官方GPG密钥:

curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

5. 使用以下指令设置稳定版仓库

sudo add-apt-repository "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/ $(lsb_release -cs) stable"

或者

sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu  $(lsb_release -cs) stable"

6. 更新源：sudo apt-get update
7. 安装最新版本的Docker Engine-Community和containerd:

sudo apt-get install docker-ce docker-ce-cli containerd.io

运行Docker服务

1. 配置docker服务开机自启：systemctl enable docker

2. 启动docker服务: systemctl start docker

3.停止docker服务: systemctl stop docker

docker hub 源 加速，国外的用不了

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
