Alpine中安装Docker
前言
虽然 Alpine 最常见的用途是当成 Docker 容器的底包，但实际其本身也是个正经的 Linux 发行版，有系统镜像体积小，安装迅速和消耗内存少的特点。
上文教大家通过alpine镜像购买1GB磁盘的低价阿里云ESC，本文来说一下在 Alpine 里安装 Docker 的过程。
软件源设置
首先要把 community 这一行取消注释。
vi /etc/apk/repositories#/media/cdrom/apks
http://dl-cdn.alpinelinux.org/alpine/v3.22/main
#http://dl-cdn.alpinelinux.org/alpine/v3.22/community安装 docker
然后运行以下命令更新软件源并安装 docker && docker-compose。
apk update && apk add docker && apk add docker-composealpine:~# apk update && apk add docker && apk add docker-compose
fetch http://dl-cdn.alpinelinux.org/alpine/v3.22/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.22/community/x86_64/APKINDEX.tar.gz

alpine:~#把 docker 添加到开机自启
rc-update add docker boot启动 docker 服务
service docker start最后可以运行 docker version && docker compose version，查看程序版本。
docker version && docker compose version如下就是安装成功。
alpine:~# docker version && docker compose version

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Docker Compose version v2.36.2至于 docker 的使用方法，就和其他 linux 发行版一模一样。
