[Bug] Setting up helm chart with external MySQL throws error on secretName

[esn89]

What are you really trying to do?

Trying to run temporal with MySQL hosted as CloudSQL instance on GCP, with Cloud Proxy Sidecar

Describe the bug

Deploying it via ArgoCD like so:

I don't expect have to pass in the "password", nor an "existingSecret" because this is the password-less way to authenticate (workload identity https://github.com/temporalio/helm-charts/pull/498) to CloudSQL. I know that it is supported because I saw the code here:

https://github.com/temporalio/helm-charts/blob/main/charts/temporal/values/values.cloudsqlproxy.yaml

On top of that since I am not deploying a cluster-version of MySQL, I didn't pass in secretName. However, in my code above, I passed in something just as a placeholder to see if the error would go away.

Because of all this, I am getting an error of:

Error: template: temporal/templates/server-secret.yaml:10:53: executing "temporal/templates/server-secret.yaml" at <include "temporal.persistence.secretName" (list $ $store)>: error calling include: template: temporal/templates/_helpers.tpl:367:4: executing "temporal.persistence.secretName" at <include (printf "temporal.persistence.%s.secretName" (include "temporal.persistence.driver" (list $global $store))) (list $global $store)>: error calling include: template: no template "temporal.persistence.mysql.secretName" associated with template "gotpl" Use --debug flag to render out invalid YAML

nor a "secretName" (

Minimal Reproduction

Environment/Versions

GKE Cluster version 1.29

I'm also encountering this while attempting to run parallel to mysql in a local cluster.

I'm also encountering this while attempting to run parallel to mysql in a local cluster.

Actually I notice from one of the examples that they use driver: sql for the mysql installation. I also used driver: mysql initially (because that's what it looks like you should do) and got the same error message.

Switching to driver: sql it installed cleanly (although I also did have placeholders in for secretName.
