i rebase it to #521 / main

[wrenix]

first look at:
#517 (comment)

i found option to set indent of sequence here: https://github.com/helm/chart-testing/blob/afa25e92904181aad0674f9483780bf7a76b100c/etc/lintconf.yaml#L33
but on test i only has effect on the Chart.yaml -> maybe lets create an issue for later (and just merge that).

Still broken?

[wrenix]

Oh, thispipeline failed, because it try to install it on an k8s without an prometheus-operator CRDs are preinstalled: https://github.com/nextcloud/helm/actions/runs/7775024318/job/21200687969?pr=523

two options (in my head):

• preinstall prometheus-operator
• extends servicemonitor with if (.Capabilities.APIVersions.Has "monitoring.coreos.com/v1/ServiceMonitor") (where where lint/test does not check the ServiceMonitor)

[provokateurin]

Preinstalling sounds like it will test more cases, so let's go with that.

[wrenix]

No, that is expacted behaviour. (it should failed, that hrlm try to install something, what the current k8s-cluster does not support) (PS: I thing you know it - i just answer for history/ other reader).

---

okay lets check out, how it is possible to tune the github actions (i need some more time therefore - i am working more with gitlab-ci).

[wrenix]

i split it into a smaller PR #526 - so that the first part could already be merged till i solve an ServiceMonitor / Prometheus-Operator CRDs
