@wasup-yash may I ask you to rebase this one

yes surely

[saschagrunert]

@wasup-yash do you want to give this one a rebase on top of main?

[saschagrunert]

@haircommander @kwilczynski I rebased this one and added some fixes. I guess we can follow-up with integration tests in a dedicated PR, but that's now ready to get merged from my point of view. PTAL.

[haircommander]

I worry about merging before integration tests TBH

/hold

You can lift the hold if you'd like, but we should get the tests ASAP to make sure the structure is correct IMO

I'm good with merging. Looks like we default to the CRI logger anyway.
+1 to integration tests as a followup.

[saschagrunert]

@haircommander I added an integration test to ensure the correct functionality.

@haircommander memory usage ok?

[saschagrunert]

@haircommander PTAL
