利用网站将Docker命令自动生成docker-compose
一键生成docker-compose.yml

例如：[root@ubuntu2004 ~]#docker run -d -p 80:80 --name nginx01 -v /data/nginx/html/:/apps/nginx/html/ --restart always nginx:v1.22.0-1
进行转换
[root@ubuntu2004 ~]#mkdir /data/docker-compose/nginx -p
[root@ubuntu2004 ~]#cd /data/docker-compose/nginx
[root@ubuntu2004 nginx]#vim docker-compose.yml
version: '3.3'
services:
nginx:
ports:
- '80:80'
container_name: nginx01
volumes:
- '/data/nginx/html/:/apps/nginx/html/'
restart: always
image: 'nginx:v1.22.0-1'
[root@ubuntu2004 nginx]#docker-compose up 前台执行，可查看错误
[root@ubuntu2004 nginx]#docker-compose up -d 后台执行
只删除停止的容器：docker-compose rm
停止并删除容器及镜像：docker-compose downdocker compose编写示例
