Horizon helm chart installation fails on non-OpenShift clusters. #57

Closed amilstead closed 7 months ago

amilstead commented 7 months ago

Describe the bug

Helm chart installation fails on non-OpenShift clusters.

To Reproduce

Use the quickstart instructions here with a non-OpenShift kubernetes cluster: https://opennms.github.io/helm-charts/horizon/, i.e.

helm repo add opennms https://opennms.github.io/helm-charts

helm install monms opennms/horizon --set domain=domain1.com  --create-namespace

The result is a container spec validation error for the core statefulset container: Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: [ValidationError(StatefulSet.spec.template.spec.containers[0].securityContext): unknown field "fsGroup" in io.k8s.api.core.v1.SecurityContext, ValidationError(StatefulSet.spec.template.spec.initContainers[0].securityContext): unknown field "fsGroup" in io.k8s.api.core.v1.SecurityContext]

Expected behavior

Helm install succeeds, rendered "NOTES.txt" is printed to console.

Desktop

Additional context

I would like to evaluate OpenNMS for usage in my network, I am using RKE2 as the kubernetes distro of choice.

Thank you for reporting this bug.

Would it be possible for you to test deploying the chart from the following branch https://github.com/OpenNMS/helm-charts/tree/mem/NMS-16365 ?

Hi there, thanks!

That seems to get me past the initial installation, however the workload hangs on init later, as it seems to expect an external postgres database by default.

When I get some actual time I may try deploying said database. That said, it would be nice if this were something the helm chart could support in terms of a deployment to avoid additional extra resource management overhead.
