Remove layers

[jorge07]

• Removed phpunit I favour of the one in your vendor/bin
• Removed travis.yml[EDITED]Added real travis tests[\EDITED]
• Moved to ADD instead COPY to reduce drastically the number of layers and restructured the filesystem in rootfs and devfs.

Why did you remove the Travis integration?

[jorge07]

Not using it, not useful at all, thinking on alternatives.

[1ma]

Well, if you think about it Docker Hub is already a CI service for Docker images.

[jorge07]

Not, it isn't. I'm currently thinking about tests the configuration, xdebug integration and a performance test. But I wanna keep the automated buildings in docker Hub. I'll moved into tag instead push soon.

Ah, I figured you only wanted to test that the images built fine.

I managed to do something similarish to that with Scrutinizer: https://github.com/1ma/RedisSessionHandler/blob/master/.scrutinizer.yml

Under override: you can execute arbitrary docker and docker-compose commands (in fact composer test does just that). You must first figure out how your testing environment will be and how you'll interact with it, though.

Staying on topic the PR looks fine, I just don't grok where these rootfs and devfs come from.

[jorge07]

Rootfs it's the filesystem of the base Dockerfile. Devfs it's the filesystem of the development environment.

I do it like that to avoid have multiple COPY instructions, which means a layer per instruction.

I'm second hand, I found so much easier replicate the fs structure to edit the files I need inside the container.

So, basically the original filesystem it's the alpine one. Extended by Rootfs and in the development image extended by Devfs.

So that the reason behind.
