Ubuntu安装docker

环境：

root@root:/etc/apt# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal

修改IP为静态IP：

vim /etc/netplan/00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens160:
      addresses: [192.168.1.116/24]
      dhcp4: no
      optional: true
      gateway4: 192.168.1.1
      nameservers:
          addresses: [114.114.114.114,223.5.5.5]
  version: 2
  renderer: networkd

编辑Yaml文件时，请确保遵循YAML代码缩进标准。如果语法不正确，则更改将不会应用。

完成后，运行以下命令，保存文件并应用更改：

sudo netplan apply

ubuntu@shenzhen $ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 127.0.0.53
options timeout:2 attempts:3 rotate single-request-reopen

这个意思好像就是systemd-resolved在本地自建了一个本地DNS服务器，它的上游可以通过resolvectl命令来查看，这有点类似于一些著名代理客户端的在本地的那些操作。我们可以不必修改这个127.0.0.53而花精力去研究这个systemd-resolved，它的命令行工具是resolvectl，我们应该研究它。需要找文档时可以man resolv再按几下tab就可以找到DNS相关文档。另外我建议，对于这些ubuntu的蜜汁操作，研究起来可能确实有点麻烦，我们可以花更多的功夫去研究Centos或者Debian的相关内容

通过键入以下内容验证更改：

ip addr show dev ens160
ping www.baidu.com

修改为国内源

我下边以清华源为例

编辑/etc/apt/sources.list文件, 在文件最前面添加以下条目(操作前请做好相应备份)：

cd /etc/apt
cp sources.list{,.bak}
egrep -v "^#|$" sources.list.bak > sources.list

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

更新一下

sudo apt-get update
sudo apt-get upgrade

安装docker

安装前准备

官方网址：https://www.docker.com/

官方文档：https://docs.docker.com/engine/install/

清华源Docker Community Edition 镜像使用帮助文档：https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/

安装过程

首先安装依赖:

sudo apt-get -y install apt-transport-https ca-certificates curl gnupg2 software-properties-common

信任 Docker 的 GPG 公钥:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

对于 amd64 架构的计算机，添加软件仓库:

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

最后安装

sudo apt-get -y update
sudo apt-get -y install docker-ce docker-ce-cli

查找Docker-CE的版本：

root@root:~# sudo apt-cache madison docker-cedocker-ce | 5:20.10.6~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.5~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.4~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.3~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.2~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.1~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:20.10.0~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.15~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.14~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.13~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.12~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.11~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.10~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages docker-ce | 5:19.03.9~3-0~ubuntu-focal | https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu focal/stable amd64 Packages

安装指定版本的Docker-CE：

sudo apt-get -y install docker-ce=[VERSION] docker-ce-cli=[VERSION]

示例：

sudo apt-get -y install docker-ce=5:20.10.6_3-0ubuntu-focal docker-ce-cli=5:20.10.6_3-0ubuntu-focal

删除docker

apt purge docker-ce

rm -rf /var/lib/docker
