Docker: docker-compose.yml file of nginx+mariadb+php+redis - php

Question

I want to write a docker-compose.yml of nginx+mariadb+php+redis,
I read the documentation about compose-file,url: https://docs.docker.com/compose/compose-file/#versioning
format is like this:
version: '2'
services:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
networks:
- front-tier
- back-tier
redis:
image: redis
volumes:
- redis-data:/var/lib/redis
networks:
- back-tier
volumes:
redis-data:
driver: local
networks:
front-tier:
driver: bridge
back-tier:
driver: bridge
But I don't know how to write the compose-file of nginx+mariadb+php+redis,I want to reference some examples.And,I use the official images of Docker Hub,url: https://hub.docker.com/explore/
**ps:**software version:
OS:centos7.2
nginx:latest
php:latest
mariadb:latest
redis:latest

Answer 1

I would go with something along these lines:
version: '2'
services:
web:
container_name: my_app
build: .
links:
- redis
- mariadb
nginx:
container_name: nginx
image: nginx
links:
- my_app
ports:
- 80:80
- 443:443
redis:
container_name: redis
image: redis
mariadb:
container_name: mariadb
image: mariadb
So create a dockerfile for your project, and extend the official PHP image by adding your files like in the readme.
This docker-compose.yml will start your container and link it to the nginx container. This means it will be available under my_app hostname, and you will need to add your own nginx config to pass the requests to that container.
Redis an mariadb will also be triggered by docker-compose and will be made available inside your app container under hostnames redis and mariadb.
Nginx should be the only container with ports exposed on the host.
The dockerfile above is not a complete solution, you will need to add an nginx config, and probably provide some environment variables here and there.
I hope this helps.
