Isolate PHP applications with Docker

Question

I am trying to setup set of docker containers to serve couple of applications. One of my goals is to isolate PHP applications from each other.

I am new to Docker. So only idea i came up with is to create a dedicated php-fpm container per-application.

I started with official image: php:7.0-fpm but now I think that I may need to create my own general purpose pfp-fpm container (based on mentioned above), add some programs to it (such as ImageMagick) and instantiate couple of such php-fpm+stuff containers per PHP-application, setting up volume pointing strictly to that application source code.

Can anyone help me with this query?

Thanks.

Here is what you can try. You can make Dockerfile starting with FROM php:7.0-fpm, with your common programs installed in it.

Then you can make a multiple other Dockerfiles (each in their different folder), starting with FROM <yourFirstImage>, and declaring specifics to each php applications.

I hope, the above explanation will be helpful to you.
