The current CRD from `mix bonny.gen.manifest` doesn't work on later version of k8s

[mruoss]

oh, that's great! I'm keen to see your approach. Also feel free to open a "WIP" PR to start a discussion even if it's not ready to be merged...

[mruoss]

@danhawkins We need to provide the CRD in its new format, including the spec yes. open_api_spex is used for creating APIs, no? Can you elaborate in how this lib could help us? Also have a look at the discussions in #9.

@FreedomBen your last post sounded so promising! What happened?

[mruoss]

yup. Closed yours ;)

Edit: as mine also addresses some other problems.

[mruoss]

For people looking for a solution, the generated CRD should work now (since version 0.5.2), once you have added the following entry to your config.exs:

config :bonny,
  api_version: "apiextensions.k8s.io/v1"

[mruoss]

Hey @FreedomBen, did you get amywhere with this?

[FreedomBen]

@mruoss yes! My operator got re-prioritized for a couple of sprints due to unexpected important stuff, but I'm back on it as of yesterday. I've got most of the work done now, I'm just testing. Unless something unexpected happens, I think I'll have it ready for PR by the end of the week. If things went really well (which rarely happens to me in software lol) it might be ready for PR this evening (US timezone).

Do you need it now?

[FreedomBen]

Getting very close 🤞

[danhawkins]

I'm currently stuck with this issue using later version of k8s, the manifest generated will not work, we need to provide the open api spec right? What about using something like https://github.com/open-api-spex/open_api_spex

[sleipnir]

Any updates here? I'm also stuck in my Operator :(

[mruoss]

Hmm... it looks like Cory had already implemented something. Can anyone test this? What happens if you add this to your config.exs:

config :bonny,
  api_version: "apiextensions.k8s.io/v1"

Edit: See #101

[mruoss]

It would be nice ot there was a way to actually define the openapi schema...

[sleipnir]

When use this option generated file use api_version specified in configuration.
But without the proper schema we still can't apply the resources in kubernetes:

minikube start
😄  minikube v1.26.1 on Debian 11.0
✨  Using the docker driver based on existing profile
👍  Starting control plane node minikube in cluster minikube

Oh boy... seems like typos in #101. What if you manually change

• scheme to schema
• openAPIV3Scheme to openAPIV3Schema

No... still not... additionalPrinterColumns should not be part of the schema... this looks all wrong (still)

Yes I know https://github.com/sleipnir/bonny/blob/811f50c60a8e41533ca562f4a8d3643b35dc1af3/lib/bonny/crd.ex#L172

[mruoss]

Opened a pull request (#143) where I try to fix this. But we don't have integration tests here yet. Need to test that first.

[sleipnir]

I think we created a PR to fix the same thing :D #144

[sleipnir]

What do you mean exactly?

Ignore my previous comment. I had taken a test wrong

[sleipnir]

@mruoss The new version works accordingly. I think there's enough material to spawn a new version of bonny now wdyt?
