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
[email protected]:~# 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）
[email protected]:~# 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.

[email protected]:~# curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | apt-key add -
OK
[email protected]:~# 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
[email protected]:~# sudo add-apt-repository \
> "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
> $(lsb_release -cs) \
> stable"

Processing triggers for systemd (245.4-4ubuntu3.15) ...6.安装好 看一下docker版本
[email protected]:~# docker version

7.开机启动设置
#看一下docker开机启动状态
[email protected]:~# 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
[email protected]:~# 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

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
[email protected]:~# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://ft5scn333r.mirror.aliyuncs.com"]
}
#加载信息 重启docker
[email protected]:~# systemctl daemon-reload
[email protected]:~# systemctl restart docker
#看一下是否生效了 ...代表省略
[email protected]:~# docker info
