Issue

• I tried to install / update CloudBees CI using Helm and the command failed with an error like the following:

Error: template: cloudbees-core/templates/cjoc-statefulset.yaml:137:20: executing "cloudbees-core/templates/cjoc-statefulset.yaml" at <include "persistence.storageclass" .>: error calling include: template: cloudbees-core/templates/_helpers.tpl:313:7: executing "persistence.storageclass" at <(.Values.Persistence.StorageClass) and (ne "-" .Values.Persistence.StorageClass)>: can't give argument to non-function .Values.Persistence.StorageClass

Environment

• CloudBees CI (CloudBees Core) on Modern Cloud Platforms
• Helm Chart cloudbees/cloudbees-core < 3.15.0
• Helm 3

Related Issues

• CPLT2-6638: Syntax error is making the chart fail with recent helms
• helm/charts #7711: Issue with go 1.14.0, Helm, 3.1.1

Explanation

A syntax issue in the CloudBees Core helm chart prior to version 3.15.0 prevent helm templates to be rendered when using a version of helm compiled with go 1.14.

Resolution

Upgrade / Install CloudBees CI to version 3.15.0 or later.
