most of the dockerfiles use Fedora 20 as base image

[adimania]

Fedora 21 is released and we should move to Fedora 21 as base image instead of Fedora 20. However there is a chance that some dockerfiles may break. Is there some sort of CI to test once the dockerfiles are changed or do we do it manually? In absence of a CI, may be we can try to have one at travis or circleCI.

Hi @adimania This is definitely something we need to address. Right now it's all manual. We brought this up during the past couple of Fedora Cloud SIG meetings.

Fedora does have a Jenkins instance here:

https://fedoraproject.org/wiki/Jenkins@infra

I haven't looked into it to much, but I need to. Some things to consider / think about for this new process -

1. What do we expect from this automation?
   build, run, give expected results
2. What are some things that might trigger a build?
   docker update, fedora update, app update, script updates, new app is added to repo
3. How to rebuild a single app?
   maybe with release branches. I need to look into this as well. We don't want to rebuild every image in the repo because someone changes a README file.

We do meet every Wed @ 19:00:00 to 20:00:00 UTC

So, we probably need to create a ticket here and start working it:

I would start working towards it in a few days. I need to look into jenkins a bit more before I do anything concrete with the Fedora's Jenkins setup.

@scollier @adimania I have some experience in Jenkins. Let me know if I can help.

Let us start with a basic build test. This test will just make sure that all the dockerfiles in a branch can be build successfully. We can use Jenkins git plugin instead of git clone in the code below.

set -e
# Command below will help in saving disk but increases bandwidth usage and time of the test
# docker images -q | xargs docker rmi 
git clone https://github.com/fedora-cloud/Fedora-Dockerfiles
cd Fedora-Dockerfiles
git checkout $test_branch
for stack in `ls`
do 
  cd $stack 
  docker build --rm -t fed-jenkins/$stack .
done

If this looks good to you guys, I would try to make it work in a local machine here and then eventually move it to Fedora's Jenkins setup.
Going forward, I would like to have a test.sh in every stack which can be executed by Jenkins to validate the stack. Does this sounds good?

I tried running the script above with some minor modifications but everything seems to be failing with error:
filesystem-3.2-27.fc21.x86_64 was supposed to be removed but is not!

This has been fixed by @adelton in PR #174. Having said that, all the Dockerfiles still need to be tested. Most of the ones I tested worked, but I didn't test every one of them.
