从 docker compose 启动单个容器
注意:使用Docker compose之前,先要安装docker
创建 docker compose文件
docker compose 文件可在任意目录,创建文件名为docker-compose.yml 配置文件,要注意前后的缩进
[root@ubuntu1804 ~]#docker-compose --version
docker-compose version 1.25.4, build unknown
[root@ubuntu1804 ~]#mkdir /data/docker-compose
[root@ubuntu1804 ~]#cd /data/docker-compose
[root@ubuntu1804 docker-compose]#vim docker-compose.yml
[root@ubuntu1804 docker-compose]#cat docker-compose.yml
service-nginx-web:

container_name: nginx-web
expose:
- 80
- 443
ports:

- "443:443"

注意:必须要在docker compose文件所在的目录执行:
