How to properly cross docker containers?

Question

Docker

I can't figure out how to link together two apache and php docker containers - this one and this one .
Those. the option is clear when apache and php are in the same container, but to make these two work together?

Answer 1

It all depends on the interaction model between apache and php that you require.
Roughly speaking: how many processes - so many containers.
If you look closely at the versions of the php images, you can see that they provide different tools (look at CMDin Dockerfile). So, for example, 7.0-fpman image is a php-fpmdaemon process. But this 7.0-cliis just launching the php interpreter in interactive mode ( php -a). The version 7.0-apacheis generally an Apache server that can run php scripts.
Accordingly, if you need an Apache + php-fpm model, then we take a container apacheand knit it with a php:fpm. If you need Apache to run php scripts directly, take one php:apache.
