[Feature Request] Expose Service trafficDistribution in chart values

[attaluris]

Hi Temporal team,

[note: I opened this issue with the help of AI]

Could the chart expose Kubernetes Service.spec.trafficDistribution as a configurable value for the server services (at least server.frontend.service, and ideally the other server service blocks too)?

I verified this is still not supported in:

• temporal-1.1.1 (latest release as of 2026-04-22)
• main

Today, charts/temporal/templates/server-service.yaml renders the service spec with fields like type, ports, and selector, but it does not template trafficDistribution.

Likewise, charts/temporal/values.yaml exposes fields under server.<service>.service such as:

• annotations
• type
• port
• appProtocol
• membershipPort
• membershipAppProtocol
• httpPort
• httpAppProtocol

but not trafficDistribution.

That means values like this are currently a no-op:

server:
  frontend:
    service:
      trafficDistribution: PreferClose

Our current workaround is to let Helm manage the Service and then apply a separate server-side-apply patch just for spec.trafficDistribution, which works but is not as clean as having first-class chart support.

It would be great if the chart supported something like:

server:
  frontend:
    service:
      trafficDistribution: PreferClose

and rendered it only when set.

This would help users adopt the newer native Service traffic-distribution behavior without needing a chart fork or an out-of-band manifest patch.

Thanks!
