[support] How to use `--filter` with `kubectl diff`?

[wsny]

This is being caused by kubectl itself, as it will not allow the required characters for any of the filter, filter-regexp, exclude or exclude-regexp flags. See character restrictions here.

Can work around this by creating a script in your path with the following code, and using that as your KUBECTL_EXTERNAL_DIFF

$ cat _kc_diff
#!/usr/bin/env bash
dyff between --exclude=metadata.generation --set-exit-code --omit-header "$1" "$2"

$ export KUBECTL_EXTERNAL_DIFF="_kc_diff"

Thanks for the question. I will have a look at it tomorrow. I assume I can take some Kubernetes related examples to try to reproduce the issue, right?

[madhukar93]

Yes. Assuming that the versions of kubernetes, kubectl are irrelevant, any example should work.
Thanks!

I am pretty busy at the moment, but I still have this on my agenda.

Hey, thanks for bumping this. I muddled through what I wanted to do, but I'll also take a better look when I get time.
