DockerCE软件仓库在线安装方式

1.环境准备

如果你过去安装过 docker，先删掉：

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do apt-get remove $pkg; done

安装依赖：

apt-get update
apt-get install ca-certificates curl gnupg

2.添加仓库镜像源

信任 Docker 的 GPG 公钥并添加仓库：

install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] http://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  tee /etc/apt/sources.list.d/docker.list > /dev/null

3.安装

apt-get update
apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
