Missing kubeContext option in helmfile 0.41+

[astorath]

Hi!

Helmfile v0.41 dropped support for kubeContext option defined inside release. If you have several kube clusters it is very convenient to define a default kubeContext (so you don't accidently release something on different kube cluster). We used this option with different environments (which can be located in different clusters).

Looks like 0.40.3 has the same problem

The option just moved to helmDefaults for consistency. Can you try this or share an example of your configuration that does not work?

[astorath]

I know it is present in helmDefaults, but we need different kontext inside release depending on environment. Besides, every other option in helmDefaults may be overriden on per release basis

[osterman]

Oh wow, that should definitely be supported per release the same way all the other defaults can be defined per release.

@osterman Hi, I've realized that I can use environment variables (e.g. .Environment.Values) inside helmDefaults block, so there is no actual problem here.

Moreover, using different contexts inside one deployment is a bit strange, but maybe there are some use cases here.

So it's up to you to close this issue.

I have just met this problem with context. It seems to be ignored and the defaults one is taken.
