Docker 目前已经支持多种操作系统的安装运行,比如Ubuntu、CentOS、Redhat、Debian、Fedora,甚至是还支持了Mac和Windows,在linux系统上需要内核版本在3.10或以上

Ubuntu 14.04/16.04/18.04/20.04 安装docker
# step 1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl softwareproperties-common
# step 2: 安装GPG证书
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key
add -
# Step 3: 写入软件源信息
sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/dockerce/linux/ubuntu $(lsb_release -cs) stable"
# Step 4: 更新并安装Docker-CE
sudo apt-get -y update
sudo apt-get -y install docker-ce
[root@ubuntu ~]#apt purge docker-ce
[root@ubuntu ~]#rm -rf /var/lib/docker
官方文档: https://docs.docker.com/install/linux/docker-ce/centos/
CentOS 6 因内核太旧,即使支持安装docker,但会有各种问题,不建议安装
CentOS 7 的 extras 源虽然可以安装docker,但包比较旧,建议从官方源或镜像源站点下载安装docker
CentOS 8 有新技术 podman 代替 docker
因此建议在CentOS 7 上安装 docker
yum -y install docker

[root@centos7 ~]#yum remove docker-ce
#删除docker资源存放的相关文件
[root@centos7 ~]#rm -rf /var/lib/docker

python-pip 包将安装一个 pip 的命令,pip 命令是一个python 安装包的安装工具,其类似于ubuntu 的apt 或者 redhat 的yum,但是pip 只安装 python 相关的安装包,可以在多种操作系统安装和使用pip
Ubuntu:
# apt update
# apt install -y python-pip
CentOS:
# yum install epel-release
# yum install -y python-pip
# pip install --upgrade pip
基于python3 安装 docker-compose
#配置加速
[root@ubuntu2004 ~]#mkdir ~/.pip
[root@ubuntu2004 ~]#cat > ~/.pip/pip.conf <<-EOF
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
EOF
[root@ubuntu2004 ~]#apt -y install python3-pip
[root@ubuntu2004 ~]#pip3 install --upgrade pip
[root@ubuntu2004 ~]#pip3 install docker-compose
[root@ubuntu2004 ~]#docker-compose --version
docker-compose version 1.27.4, build unknown
#基于python2安装docker-compose
[root@ubuntu1804 ~]#apt -y install python-pip
[root@ubuntu1804 ~]#pip install docker-compose
[root@ubuntu1804 ~]#docker-compose --version
docker-compose version 1.25.3, build unknown
此方法安装的版本较旧,不推荐使用
#ubuntu安装,此为默认版本
[root@ubuntu1804 ~]#apt -y install docker-compose
[root@ubuntu1804 ~]#docker-compose --version
docker-compose version 1.17.1, build unknown
#CentOS7安装,依赖EPEL源
[root@centos7 ~]#yum -y install docker-compose
[root@centos7 ~]#docker-compose --version
docker-compose version 1.18.0, buil 8dd22a9
参看说明: https://github.com/docker/compose/releases
此方法安装版本可方便指定,推荐方法,但网络下载较慢
root@ubuntu:/usr/local/bin# wget https://github.com/docker/compose/releases/download/v2.17.1/docker-compose-linux-aarch64
root@ubuntu:/usr/local/bin# mv docker-compose-linux-aarch64 docker-compose
root@ubuntu:/usr/local/bin# chmod +x docker-compose
root@ubuntu:~# docker-compose version
Docker Compose version v2.17.1
