First take on running Zipkin in a Kubernetes cluster.

Note that the images depend on the latest itszero/zipkin-* images in docker-zipkin, which haven't been pushed to Docker Hub yet.

probably want to use a variable to ensure a stable tag is used as opposed to master. ex 1.9.0

I don't have a local k8s env, so if someone else can check this out, LGTM pending the couple version things.

Hey Adrian, sorry for the delay. Been busy with other stuff. I'll get this branch updated and retested tomorrow.

[codefromthecrypt]

Drones keeping you busy, eh? ;) no prob. Glad you are back online!

Hi,

I tried deploying controllers and services to my kubernetes cluster, and ran into the following issues:

• zipkin-cassandra pod starts, but repeats this message in the logs ad infinitum: Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})
• zipkin-collector: restarts, but this is probably due to cassandra not starting properly
• zipkin-web: cannot pull image due to Error: image niccaluim/zipkin-web:latest not found
• zipkin-query: cannot pull image due to Error: image niccaluim/zipkin-query:latest

I created a zipkin namespace for this test and deployed into it.
I also modified the zipkin-web service, adding some labels to the metadata, but nothing else.

env: GCE
kubectl version: 1.0.5
k8s master: 1.0.4 (GKE)
minions: 1.0.1 I think?

FWIW I see *** Importing Zipkin schema in the cassanda pod log, but I do NOT see *** Schema import complete.

heh.. we're up to 1.16.0

Mind bumping this? would be neat to have this available for the tracing workshop tomorrow.

[codefromthecrypt]

releasing 1.24.0 soon!

I think one thing that stalled this out was that k8 had a bunch of arduous ways to setup. In docker-zipkin, we use default docker toolbox docker-machine and docker-compose. I bet if we made this docker-composeable, folks could easily try it. Mind giving that a shot?

Maybe something like this?

heh I bet some things have changed in k8 since this PR. There's also some improvements in zipkin, too

if anyone's interested, happy to review changes and get this in!
