Before proceeding

• I didn't find a similar issue

Version

werf 2.10.9, 1.2.329

How to reproduce

Could not delete default keys from subcharts if subchart is defined in dependencies

if subchart has for example

resources:
  limits:
    cpu: 4
    memory: 3Gi
  requests:
     cpu: 700m
     memory: 70Mi

it is unable to override with

resources:
  limits: null
  requests: null

the same as helm/helm#9027

Result

default values are in rendered files

Expected result

default values are overrided

Thank you for your feedback. We will work on addressing this issue.​

@shcherbak You said that you specified null overrides as this:

resources:
  limits: null
  requests: null

but instead it must be like this:

# .helm/values.yaml
mysubchart:  # name of the subchart as defined in dependencies
  resources:
    limits: null
    requests: null

If done this way is the problem still persist?

@ilya-lesikov of cource I specified values with mysubchart key

We'll look into it. Either Helm issue or we messed up somewhere when backporting changes from Helm upstream.

@ilya-lesikov this issue fixed in helm 3.17.1 , release planned for 12-Feb

Thanks. Though it will take some time to update Helm in werf/Nelm, since we are in the middle of a big refactoring.
