Hi,

could you please look into this and if possible review / merge? Would really appreciate this, thanks.

Hi @cdav @JackOneil @luborpetr, thanks for this contribution! The code looks good.

One change needed before we merge: please add the default values to values.yaml under both server and client.

server:

...existing fields...

podLabels: {}
nodeSelector: {}
tolerations: []
affinity: {}

client:

...existing fields...

podLabels: {}
nodeSelector: {}
tolerations: []
affinity: {}

Right now these fields are only in values.schema.json, so they won't appear when users run helm show values.
Every other configurable field in this chart is listed in values.yaml, let's keep that consistent.

Once that's in, happy to merge!

Hi @cdav @JackOneil @luborpetr , thanks again for this contribution! We've decided to merge this PR as-is.
We've opened #78 to add the values.yaml defaults on top.
Appreciate your work on this!
