docker compose 学习笔记

docker compose 主要是对一些列的容器程序集中的操作管理

依然参考菜鸟的内容
大佬的作品学习一下

确认一下compose 已安装，没有自行安装

docker compose version    

Docker Compose version v2.10.2

命令差不多，build可以使用远程镜像也可以用本地的dockerfile

开始构建

 docker compose up -d

从上面的yml中可以了解到，compose构建容器可以通过镜像构建，也可以通过compose构建，compose构建是独立的网络，不能把compose以外的容器link起来。特别要注意的是因为我的本地是mac的M1芯片，系统架构的不同会导致容器无法启动成功，报错

exec /cmd/binlog: exec format error

yml中已经注释。其他标签基本与dockerfile 中大同小异。
