Docker环境安装

删除旧的docker

1
root@ubuntu2204:~# for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

一、使用仓库安装docker

安装依赖环境

1
2
root@ubuntu2204:~# apt-get update
root@ubuntu2204:~# apt-get install ca-certificates curl gnupg

添加docker-ce软件源

注：Ubuntu apt仓库中默认有较新的版本，不添加docker源也可安装。
