[ebuildy]

Please use stackoverflow to ask help, github issue is for bugs or feature requests.

You are using Helm chart elasticsearch, version 7.17.1, values.yaml "syntax" is here : https://github.com/elastic/helm-charts/blob/v7.17.1/elasticsearch/values.yaml#L11

Dont use values.yaml from master branch!

@ebuildy still the same,

hello, helm-chart version 8 it's not ready yet. we are working on it (no ETA) and for now the last helm-chart available is 7.17.1 as you can see here

[Sparkycz]

Having different versions of the Helm chart in the repository and in the GIT master is very confusing. Please get rid of it in the future.

I just upgraded from 7.17.1 to 8.1.0. Now facing a similar issue.
helm upgrade --install elasticsearch elastic/elasticsearch -n gitlab -f elasticseach-values.yaml
Error: UPGRADE FAILED: template: elasticsearch/templates/statefulset.yaml:303:27: executing "elasticsearch/templates/statefulset.yaml" at <.Values.roles.master>: can't evaluate field master in type interface {}

The big concern is when I try to revert back to version 7.17.1, this time, I can't go back as the error says there is already a version moved on 8.1.0 (usr/share/elasticsearch/data) file has version maintained.

8.1.0 is still not supported. see #1594
