给机子配置 docker 环境

仅仅适用于 debian

仅作为 Debian 的步骤摘要，其他系统以及最新操作请见：Debian | Docker 文档 — Debian | Docker Docs
注意选择自己的操作系统

先卸载之前冲突的包

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

设置 Docker 的 apt 仓库

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

安装 Docker 软件包

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

验证安装

docker --version
docker compose version

换源

因为 GFW 等原因，国内拉取镜像很慢。
