Some changes to make the helm chart work

[stevelaclasse]

Hi everyone,

i have tried this helm chart on a Kubernetes cluster an notice that it is not properly working.

The first problem was that the Deployment kind of the chart was not supported anymore, you need to change it to ; "apps/v1" as it is in this git repo.

The second problem is that the Kubernetes service (with his port) overwrites the application port values. You will probably obtain an error with something containing "java.lang.NumberFormatException: For input string: tcp://xx.xx.xx.xx".
You solves this by just changing the service name in the manifest file; in the metadata, replace the name attribute with: name: "{{ template "gitbucket.fullname" . }}-service" .

In order to apply those changes you will need to fetch the helm repo locally and apply the changes manually before installing the helm chart.

I hope it helps someone else and thanks again for setting up this chart.
