[bug] extra newline in config files

[ishioni]

Describe your Issue

Chart version 4.5.1 replaced indent with nindent for config files. This unfortunately ends up rendering those config files with a newline prepended

Logs and Errors

As you can see in my local flux repo PR, extra config files are now rendered with a newline and a |2- instead of a |-, and an added newline as a bonus. This in turns errors out nextcloud with an error

Config file has leading content, please remove everything before "<?php" in local.config.php
Fatal error: Uncaught Error: Typed static property OC::$server must not be accessed before initialization in /var/www/html/index.php:71 Stack trace: #0 {main} thrown in /var/www/html/index.php on line 71

Additional context, if any

[DanishVaid]

+1 - this break was introduced in this PR here: https://github.com/nextcloud/helm/pull/465

I also added a comment on that PR to expand upon the issue being seen

[nafets227]

+1 same issue here, rolling back to 4.5.0

[jessebot]

looking! Apologies for the inconvenience!

Update: looks like we have a potential fix in #465.

Update again: I marked the current release as a pre-release, meaning not ready for production, and linked to both this bug and the PR that is in the works to fix it :pray:

[djbobyd]

Hello, as I think my issue is related I decided not to open another one. I noticed that the extraVolumes were broken in 4.5.1: I was getting the following error when trying to upgrade: YAML parse error on nextcloud/templates/deployment.yaml: error converting YAML to JSON: yaml: line 192: did not find expected key I did a little digging and what I found is that the nindent in the deployment template for the extraVolumes was wrong. It is currently:

{{- with .Values.nextcloud.extraVolumes }}
{{- toYaml . | nindent 6 }}
{{- end }}

when I change it to "8" the template renders without any issues. Hope you can fix this as well with the above PR. Thanks!

[wrenix]

good hint @djbobyd i but it also into #476

(PS: @ishioni Nice bot which makes an helm diff in context of fluxcd - what bot software do you use for it?)

[DanishVaid]

This was meant for the PR with the fix

Hmm, I'm trying to test but seeing an odd error during chart rendering (shown below). I don't think this is tied to your change. Seeing if I can figure out what it is

Error: template: test/charts/postgresql/templates/primary/svc.yaml:11:14: executing "test/charts/postgresql/templates/primary/svc.yaml" at <include "common.labels.standard" (dict "customLabels" .Values.commonLabels "context" $)>: error calling include: template: test/charts/mariadb/charts/common/templates/_labels.tpl:11:27: executing "common.labels.standard" at <include "common.names.name" .>: error calling include: template: test/charts/mariadb/charts/common/templates/_names.tpl:11:18: executing "common.names.name" at <.Chart.Name>: nil pointer evaluating interface {}.Name helm.go:84: [debug] template: test/charts/postgresql/templates/primary/svc.yaml:11:14: executing "test/charts/postgresql/templates/primary/svc.yaml" at <include "common.labels.standard" (dict "customLabels" .Values.commonLabels "context" $)>: error calling include: template: test/charts/mariadb/charts/common/templates/_labels.tpl:11:27: executing "common.labels.standard" at <include "common.names.name" .>: error calling include: template: test/charts/mariadb/charts/common/templates/_names.tpl:11:18: executing "common.names.name" at <.Chart.Name>: nil pointer evaluating interface {}.Name

[jessebot]

Thank you, @wrenix for tending to this!

A new release, 4.5.2, should be out since this job completed. We tested it in the pipeline and I tested it on my VPS via Argo CD before pushing it up.

@ishioni , @DanishVaid , @djbobyd , @nafets227 can you all please let me know if your errors are resolved after testing the latest release?

Thanks everyone for their patience and kind vibes :blue_heart:

_{edit: the release job hadn't finished yet, so I had to link to it :facepalm:}

[ishioni]

Job's finished but the chart doesn't seem to available yet :/

[nafets227]

Job 81 needs to finish before we can see the new chart version in the helm repo (it's pushing the content from gh-pages branch to the GitHub pages).

I´m waiting for it, too, to start testing

[jessebot]

@nafets227 great catch! Forgot that it takes a bit because I think the nextcloud org is low on GHA minutes and they're still implementing self hosted runners. Sorry about that, @ishioni :pray:

[jessebot]

ok, that job has completed and after:

helm repo update
helm show chart nextcloud/nextcloud

I finally get:

CI Tests are running ...

[nafets227]

works here :)

So finally I can confirm that chart version 4.5.2 solves the issue introduced with 4.5.1 for me.

thanks @jessebot @wrenix for quick fix. And thanks to you and all the next cloud team for the great product and helm chart!

[ishioni]

Confirm on my end too
