The template you provided here is the part of helm chart, which can be deployed using `helm` cli, not using `kubectl apply`. — mchawre, Sep 05 '19 at 11:36
thanks for the reply. do you have any guide or relevant commands to try! — , Sep 05 '19 at 11:38
The code from where you pulled this helm chart, should have the instructions to install that chart. — mchawre, Sep 05 '19 at 11:39

The template you provided here is the part of helm chart, which can be deployed using helm-cli, not using kubectl apply.

More info on using helm is here.

You can also get the instructions to install nexus using helm in this official stable helm chart.

Hope this helps.
