Best practices for a php docker image

[cdudevops]

Hello Bret,

I follow you since a long time and I like very much to watch your courses and presentations.

In my company we have lots of web apps (apache,php,mysql) installed on physical hosts and I want to migrate them to docker, to move in this direction.

Can you provide me some best practices/guidelines for docker apache/nginx + php image ? Should I keep them separately or in the same container ? Which php image will be better: alpine, official php image, ubuntu+php ?

I saw your presentation about Nodejs Rocks in Docker, maybe we can see something for PHP :).

Thanks!

A bit outdated way to combine into a single container image: https://github.com/BretFisher/php-docker-good-defaults

That's what you have to do in Docker/Swarm because it doesn't have a way to link multiple containers together for non TCP/IP traffic (like sockets).

Kubernetes does support this with Pods, which can be 2 containers with the same process list, volumes (file sockets), and network namespace (localhost). I don't have an example of that but it would be using something like php-fpm + nginx official images out of the box (which is my preferred way).
