I'm trying to configure a helm chart via pulumi and golang. According to the helm chart documentation default components can be removed by setting the config to null. I managed to set the desired config values for the helm chart in my pulumi script, but it's not possible to set config values to null.
Update:
It seems that the custom abstraction layer on top of the pulumi helm chart resource could not handle the config. I have added a minimal working example which uses the helm chart resource directly and its working as expected:
package main
import (
helmv3 "github.com/pulumi/pulumi-kubernetes/sdk/v3/go/kubernetes/helm/v3"
"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)
func main() {
pulumi.Run(func(ctx *pulumi.Context) error {
_, err := helmv3.NewChart(ctx, "otel-collect", helmv3.ChartArgs{
Chart: pulumi.String("opentelemetry-collector"),
Version: pulumi.String("0.31.1"),
FetchArgs: helmv3.FetchArgs{
Repo: pulumi.String("https://open-telemetry.github.io/opentelemetry-helm-charts"),
},
Values: pulumi.Map{
"fullnameOverride": pulumi.String("otel-collector"),
"mode": pulumi.String("deployment"),
"config": pulumi.Map{
"receivers": pulumi.Map{
"jaeger": pulumi.Map{
"protocols": pulumi.Map{
"thrift_compact": nil,
},
},
"prometheus": nil,
},
"service": pulumi.Map{
"pipelines": pulumi.Map{
"metrics": nil,
},
},
},
},
})
if err != nil {
return err
}
return nil
})
}
In this scenario I want to set the prometheus config to null but when this chart is deployed the default values for prometheus are set. I have also tried "prometheus": pulumi.Any(nil), but this also does not change the config.
The issue was caused by an abstraction layer I put on top of the pulumi helm resources.
