How to run php-fpm in docker-compose.yml? - docker

Question

I tried to build a container used docker-compose. So I wrote the dockerfile and docker-compose.yml like following:
dockerfile
FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y expect
RUN apt-get -y install software-properties-common
RUN apt-add-repository ppa:ondrej/php
RUN apt-get -y install php7.1 php7.1-fpm
RUN apt-get install php7.1-mysql
RUN apt-get -y install nginx
RUN apt-get -y install vim
COPY default /etc/nginx/sites-available/default
COPY www.conf /etc/php/7.1/fpm/pool.d/www.conf
COPY test /var/www/html/test
CMD service php7.1-fpm start && nginx -g "daemon off;"
docker-compose.yml
version: '3'
services:
web:
build:
context: .
dockerfile: Dockerfile
ports:
- "3011:80"
When I run following command, the php7.1-fpm is run success.
docker-compose build
docker-compose up --force-recreate -d
But I want to move the CMD from dockerfile to docker-compose, so I changed the file like following:
docker-compose.yml
command: service php7.1-fpm start && nginx -g "daemon off;"
But this time php7.1-fpm is not running.
How to fix this issue, so that I can run php7.1-fpm in docker-compose.yml?

Answer 1

you can not use service php7.1-fpm start in your Dockerfile, because container is just a process, not a real virtual machine, main process down and others will down neither
docker suggest you to divide them in different container, php-fpm, nginx, single image single container
solution:
docker/php-fpm/Dockerfile
FROM php:7.2-fpm
RUN docker-php-ext-install pdo pdo_mysql mbstring
docker-compose.yml:
version: '2.1'
services:
nginx:
image: nginx:latest
ports:
- 8001:80
volumes:
- ./:/app
# nginx configs
- ./docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
php-fpm:
build: ./docker/php-fpm
volumes:
- ./:/app
php-composer:
restart: 'no'
image: composer
volumes:
- ./:/app
command: install
nodejs:
restart: 'no'
image: node:8.9
volumes:
- ./:/app
command: /bin/bash -c "cd /app && npm install && npm run prod"
