Run Fluo in Kubernetes and update documentation

[mikewalch]

The Fluo docker container has been tested in Marathon but should also be tested in Kubernetes and the documentation at https://fluo.apache.org/docs/fluo/1.2/administration/run-fluo-in-docker should be updated with instructions for how to do this.

Docs can be updated by making PR to the repo apache/fluo-website that updates https://github.com/apache/fluo-website/blob/gh-pages/_fluo-1-2/administration/run-fluo-in-docker.md

@mikewalch Testing with Minikube is acceptable? and Is there any smoke test to guarantee that fluo is running in docker container ?

[mikewalch]

Testing with MiniKube works! If the container starts up and is running idle with no exceptions, you should be good.

@mikewalch I am using windows 10, minikube I run the below commands in windows power shell. The apache/fluo is not building the container and failing with the status "CrashLoopBackOff"

PS C:\kubernetes> kubectl.exe run apache-fluo-test --image=apache/fluo
deployment "apache-fluo-test" created
PS C:\kubernetes> kubectl get pods
NAME READY STATUS RESTARTS AGE
apache-fluo-7674c8d78-fbzds 0/1 CrashLoopBackOff 7 19m
apache-fluo-test-66dd7fcf6b-5j2tb 0/1 CrashLoopBackOff 3 1m
hello-nginx-6f9f4fc7dd-9w4jv 1/1 Running 0 3h

Attached is log and K8 dashboard.

I have noticed that docker is not running in my local machine since virtualbox is installed. I will keep you posted once I figure that out. In the mean time, please advise me If you find anything more needed to start fluo service.

I have few suggestions for documentation updates.
