The content docker-compose file as below
version: '3'
services:
WEB01:
image: nginx:latest
container_name: "web01"
hostname: web01
ports:
- "8888:80"
- "8443:443"
- "2233:22"
#deploy:
# resources:
# limits:
# memory: 512M
#mem_limit: 512m
volumes:
- ./data_web01:/mnt_nfs
networks:
- bridge
restart: always
DB01:
image: mysql:latest
container_name: "db01"
hostname: db01
ports:
- "33306:3306"
- "2234:22"
command: --default-authentication-plugin=mysql_native_password
environment:

Creating and starting a container
[root@DevopsRoles docker-instance]# docker-compose up -d
The screen output terminal:
Creating network "docker-instance_bridge" with driver "bridge" Creating db01 ... done Creating web01 ... done
The result, Docker compose example
Access browser Nginx server
Checking running containers for nginx and mysql
