tempo-distributed helm install fails if gateway:enabled:true

[danstadler-pdx]

I tried deploying charts/tempo-distributed with the following in my custom yaml file:

gateway:
  enabled: true

And I get this output:

helm -n tempo-test install tempo grafana/tempo-distributed -f custom.yaml
Error: INSTALLATION FAILED: YAML parse error on tempo-distributed/templates/gateway/deployment-gateway.yaml: error converting YAML to JSON: yaml: line 103: mapping values are not allowed in this context

When running with dry-run / debug, I also get all of this:

helm -n tempo-test install tempo grafana/tempo-distributed -f custom.yaml --dry-run --debug > dryrun-gateway-true.y
aml

Ran into the same issue on the latest version.

My gateway.yaml file:

gateway:
  enabled: true
enterpriseGateway:
  enabled: true
  useDefaultProxyURLs: true
  replicas: 1

Chart info:

∟ % helm search repo grafana/tempo-distributed           
NAME                        CHART VERSION   APP VERSION DESCRIPTION                       
grafana/tempo-distributed   1.21.1          2.6.0       Grafana Tempo in MicroService mode

I've been poking around various YAML and HELM validators and haven't found any issues, yet.

Found the problem w/ some help from @hedss -

This is for the OSS version, and can be enabled/disabled explicitly:

gateway:
  enabled: true

Reference: https://github.com/grafana/helm-charts/blob/d8224757f599319e24cd8267f32b0cee43e17cc0/charts/tempo-distributed/values.yaml#L1753

This is for GET, and is automatically enabled when enterprise.enabled=true:

enterpriseGateway:
  ...

Reference: https://github.com/grafana/helm-charts/blob/d8224757f599319e24cd8267f32b0cee43e17cc0/charts/tempo-distributed/values.yaml#L2180

If gateway.enabled=true, the install will fail with the error outlined by @danstadler-pdx . Once I set gateway.enabled=false, the install completed.

It's referenced in our docs here:
