[Hawkular-dev] Container Tests

[Matt Wringe]

Currently we are not doing any tests for the Hawkular Metrics docker 
images and kubernetes configurations. This is something we really need 
to address.

We are currently using Travis which doesn't provide a nice solution for 
this space. Fabric8 has a good setup for testing kubernetes components 
with their Continuous Delivery suite (which uses Jenkins), but requires 
a machine to be setup running docker (+ OpenShift) to deploy its suite 
of docker images.

With a fabric8 continuous delivery setup, we can also remove the docker 
hub automated builds and build them as part of maven build. This would 
allow us to:
1) only publish docker images if the test suites pass on them (with 
docker hub we would have to publish the images first and then run tests).
2) to manage all the code in one spot without having to modify it in 
multiple locations (currently its managed in 3 different github repos 
which need to be synced together).
3) have a lot more control over images and how they are tagged. 
Currently docker hub is restrictive in how we handle this.

[Note: we would still be publishing out images to docker hub for others 
to consume, we would just be pushing the images that our test suite 
builds rather than ones build in docker hub itself. It also means we can 
publish to other repositories if we wish]

Anyone know if we have any machines available to setup an environment 
for these types of tests?

We could move the container stuff out of Hawkular Metrics and into its 
own git repository (which might make sense, since the Cassandra stuff is 
not necessarily metrics specific). This would mean that we don't need to 
move all the tests over to Jenkins and we could keep the current Metrics 
tests in the same CI.

Or it could be configured to only build the docker images and not all of 
Metrics (via profiles).

Anyone have any thoughts on this?

Thanks,

Matt
