网络静态IP配置

vim /etc/netplan/50-cloud-init.yaml

network:
  version: 2
  ethernets:
    ens33:
      dhcp4: false
      addresses:
        - 192.168.11.200/24
      routes:
        - to: default
          via: 192.168.11.2
      nameservers:
        addresses:
          - 114.114.114.114
          - 8.8.8.8

netplan apply

根据注释可知道，要创建文件，来保证静态网络配置的持续生效

vim /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

写入：

network: {config: disabled}

如果不做这一步，重启虚拟机后，原先的配置配置文件可能就会变成默认内容，导装静态IP配置失效

备份原先的系统默认源

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

编辑源

vim /etc/apt/sources.list

更新缓存

apt update

apt upgrade -y

安装docker

准备条件

#安装前先卸载操作系统默认安装的docker
sudo apt-get remove docker docker-engine docker.io containerd runc

#安装必要支持
sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

准备安装
阿里源（推荐使用阿里的gpg KEY）

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

#添加 apt 源:
#阿里apt源
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

#更新源 

sudo apt update 
sudo apt-get update

安装Docker

#安装最新版本的Docker
sudo apt install docker-ce docker-ce-cli containerd.io
#等待安装完成

#查看Docker版本
sudo docker version

#查看Docker运行状态

sudo systemctl status docker

### 安装Docker 命令补全工具

sudo apt-get install bash-completion

sudo curl -L https://raw.githubusercontent.com/docker/docker-ce/master/components/cli/contrib/completion/bash/docker -o /etc/bash_completion.d/docker.sh

source /etc/bash_completion.d/docker.sh
