The current datahub version should be shown instead of null. It seems that it is not being correctly picked up from the following setting:
- name: DATAHUB_APP_VERSION value: "{{ .Chart.AppVersion }}"

I've had a quick look at this.
We certainly define that variable in the frontend config here:
https://github.com/wikimedia/operations-deployment-charts/blob/master/charts/datahub/charts/datahub-frontend/templates/_containers.tpl#L83-L84
I can see that it is getting populated with the correct value and made available as an environment variable to the datahu-frontend container too:
btullis@deploy1002:~$ kubectl describe pods datahub-frontend-main-775c48cb46-sbctj |grep DATAHUB_APP_VERSION
DATAHUB_APP_VERSION: 0.9.0But it's definitely not appearing in the drop-down list.
I will look into other potential solutions to this problem.
