在Mac上使用Docker Nginx，PHP，MySQL

Question

I'm just starting to get my head around docker and want to use it for a project.

I have followed https://docs.docker.com/docker-for-mac/#explore-the-application-and-run-examples and have NGINX running fine and can see the NGINX landing page.

Do I need to install php-fpm and mySQL within my container since my container is only NGINX at this stage?

How do I configure my project on a custom domain eg project.dev . Do I need to edit an entry in /etc/hosts for 127.0.0.1 project.dev and then listen for that URL in an NGINX config?

Lastly do I need a dockerfile ? I already have my container up and my understanding is a dockerfile is only for defining your container?

An example of a dockerfile for NGINX, PHP and mySQL would be helpful to look at as well.

Thanks

No, this guide just show using nginx container in docker. But I see the container don't have php installed. And you cannot install php-fpm inside this container.

So, if you want to use nginx , php , and MySQL using docker you should pull :

1. Container which run Nginx + PHP-FPM (I recommend this image https://hub.docker.com/r/richarvey/nginx-php-fpm/ )
2. Container run MySQL ( https://hub.docker.com/_/mysql/ )

Download images

docker pull richarvey/nginx-php-fpm
docker pull mysql:5.6

Run MySQL Instance. Name it mysql56, and expose using port 3360

docker run -tid -p 3360:3306 --name mysql56 -e MYSQL_ROOT_PASSWORD=123456 -v /root/docker/mysql56/data/mysql:/var/lib/mysql  -d mysql:5.6

Run Nginx PHP+FPM instance. Link it to MySQL Instance, and name it project-dev

docker run -tid --name project-dev --link mysql56:mysql -v $(pwd):/var/www/html -p 8888:80 richarvey/nginx-php-fpm:latest

Run docker ps -a to see the running containers.

To make nginx can be accessed with address project.dev , just map it on /etc/hosts . Then access it on web browser http://project.dev:8888

Note :

• -v /root/docker/mysql56/data/mysql:/var/lib/mysql it mean I have /root/docker/mysql56/data/mysql on my mac, and map it to /var/lib/mysql in mysql56 container. So all mysql data will be backup on my local data, and will not lose when I remove the container.
• -v $(pwd):/var/www/html mean your current directory will be mapped to container. So, whatever you write in this directory will be exist on /var/www/html container.
• I use port 8888 to avoid conflict with existing web server, you can change it as you want
