ubuntu20.04系统中安装最新版docker、docker-compose流程步骤

我是在阿里云ecs上的最新ubuntu20.4系统，后面所以教程架构都会基于该版本进行

进入步骤：

0.开始先更新一下源

root@iZwz91cvaakchabbuilxg0Z:~# apt update

1.允许apt通过https使用repository安装软件包 

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

执行命令 （太长了我就...省略了）

root@iZwz984fp76m12whtx8tpgZ:~# sudo apt-get install \
>     apt-transport-https \
>     ca-certificates \
>     curl \
>     gnupg-agent \
>     software-properties-common

ca-certificates is already the newest version (20210119~20.04.2).
curl is already the newest version (7.68.0-1ubuntu2.8).
The following package was automatically installed and is no longer required:
  libsasl2-modules
Use 'sudo apt autoremove' to remove it.
...

2.添加Docker GPG key 及 验证key （国内阿里云版）

root@iZwz984fp76m12whtx8tpgZ:~# curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | apt-key add -
OK
root@iZwz984fp76m12whtx8tpgZ:~# apt-key fingerprint 0EBFCD88
pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <[email protected]>
sub   rsa4096 2017-02-22 [S]

3.添加repository（国内阿里云版）

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

执行命令

root@iZwz984fp76m12whtx8tpgZ:~# sudo add-apt-repository \
>    "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
>    $(lsb_release -cs) \
>    stable"

Hit:2 http://mirrors.cloud.aliyuncs.com/ubuntu focal-updates InRelease
Hit:3 http://mirrors.cloud.aliyuncs.com/ubuntu focal-backports InRelease                                         
Hit:4 http://mirrors.cloud.aliyuncs.com/ubuntu focal-security InRelease

Get:6 https://mirrors.aliyun.com/docker-ce/linux/ubuntu focal/stable amd64 Packages [13.5 kB]
Fetched 71.2 kB in 1s (119 kB/s)
Reading package lists... Done

4.更新源 (...省略)

root@iZwz984fp76m12whtx8tpgZ:~# apt-get update
Hit:1 http://mirrors.cloud.aliyuncs.com/ubuntu focal InRelease
Hit:2 http://mirrors.cloud.aliyuncs.com/ubuntu focal-updates InRelease

5.安装最新版docker  (...表示省略)

root@iZwz984fp76m12whtx8tpgZ:~# apt-get install docker-ce docker-ce-cli containerd.io
Reading package lists... Done
Building dependency tree

6.安装好 看一下docker版本

root@iZwz984fp76m12whtx8tpgZ:~# docker version

7.开机启动设置

#看一下docker开机启动状态
root@iZwz984fp76m12whtx8tpgZ:~# systemctl list-unit-files | grep docker

docker.service                         enabled         enabled

docker.socket                          enabled         enabled



#没有的话就要设置，开机启动命令

systemctl enable docker

8.安装docker-compose

#github源超时  大环境是这样 没办法只能换源
curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose


#执行命令
root@iZwz984fp76m12whtx8tpgZ:~# curl -L "https://get.daocloud.io/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

                                 Dload  Upload   Total   Spent    Left  Speed

root@iZwz984fp76m12whtx8tpgZ:~# chmod +x /usr/local/bin/docker-compose

root@iZwz984fp76m12whtx8tpgZ:~# docker-compose --version

Docker Compose version v2.2.2

9.配置阿里云镜像仓库加速

#在/etc/docker/目录下创建daemon.json文件 输入你的加速地址 注意是你的 老铁
root@iZwz984fp76m12whtx8tpgZ:~# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://ft5scn333r.mirror.aliyuncs.com"]
}
#加载信息 重启docker

root@iZwz984fp76m12whtx8tpgZ:~# systemctl daemon-reload
root@iZwz984fp76m12whtx8tpgZ:~# systemctl restart docker
#看一下是否生效了  ...代表省略
root@iZwz984fp76m12whtx8tpgZ:~# docker info
