(default: directory name)
-c, --context NAME Specify a context name
--verbose Show more output

--no-ansi Do not print ANSI control characters
-v, --version Print version and exit
-H, --host HOST Daemon socket to connect to

--skip-hostname-check Don't check the daemon's hostname against the
name specified in the client certificate
--project-directory PATH Specify an alternate working directory
(default: the path of the Compose file)
--compatibility If set, Compose will attempt to convert keys
in v3 files to their non-Swarm equivalent
--env-file PATH Specify an alternate environment file
Commands:
build Build or rebuild services
config Validate and view the Compose file
create Create services

events Receive real time events from containers
exec Execute a command in a running container
help Get help on a command

创建并启动containers
创建并启动docker-compose.yml或docker-compose.yaml文件中的service
docker-compose up # 不推荐
执行结果如下：
注意： 打印详细日志，执行ctrl+c退出时容器会停止，一般用于 调试
创建网络
由上图可见，通过docker-compose创建容器时，也会 创建网络
查看docker网络：
docker network ls
执行结果如下：
创建一个新的docker网络，是bridge网络模式
查看网络详细信息
docker network inspect docker_tomcat_default
执行结果如下：
[

"Name": "docker_tomcat_default",
"Id": "0d5e26732eb3ad42304de4ff115ecf244e5c62d7cc9343d61b5f09db51feaf71",

ip网段是172.30.0.0/16
查看linux系统网络
ip a
执行结果如下：
虚拟网卡 红框 部分0d5e26732eb3，与 docker网络0d5e26732eb3， 是一致的
注意网段
docker-compose 创建容器时，也会创建网络，该网络ip网段 与 默认bridge网络的ip网段，一般不同docker run创建容器时，使用 默认bridge网络
2个容器的网段不一样，无法网络通信
解决方法
创建自定义bridge网络，在 docker-compose.yml文件中指定该网络，然后启动
通过docker run创建容器时，也指定该网络，见：
https://www.malaoshi.top/show_1EF5xlsxdwTZ.html
后台启动
正常启动，不会打印详细日志
docker-compose up -d
指定文件启动
要执行 xxx.yml文件时，按照下面格式指定：
docker-compose -f abc.yml up -d
列出 containers
列出docker-compose.yml或docker-compose.yaml文件中的 containers
docker-compose ps
停止service
停止docker-compose.yml或docker-compose.yaml文件中的service
docker-compose stop
停止service并删除
停止docker-compose.yml或docker-compose.yaml文件中的service，并删除containers, networks, images, and volumes
docker-compose down
启动service
启动docker-compose.yml或docker-compose.yaml文件中的service
docker-compose start
相当于docker exec
docker-compose exec 名字 bash
其中 名字 是在docker-compose.yml定义的名字
