Is this a BUG REPORT or FEATURE REQUEST? BUG REPORT Kubernetes version (use ): kubernetes/master using CRI with docker What happened: Create a pod that uses a readiness probe that does an exec to command that doesnt exist See the following in logs: What you expected to happen: No error in log, expected the event to properly be thrown. How to reproduce it (as minimally and precisely as possible): See above. Anything else we need to know: Nope.
this is a regression.
debugging, will post a fix once found.

-- thanks for the other reports. at least now we have a reliable reproduction.
The problem appears to be the following: has a that correlates containers to a . It uses the type . event recorder library we use in the prober works with . If it doesn't get one of those, it expects the passed in object to implement List. As a result, we are passing a v1.ObjectReference the recorder was not expecting.
The bug may have been introduced in , which was there since v1.6.0.
Opened for a fix.
Keep this open until 1.6 is patched.

cc not sure if this is related to your changes
I don't think so. I didn't change the identification of or which are being used there.

I always get the same message. What does this exactly mean?
We're also seeing this on 1.6.1
Seeing this in as well
How we can come to know which release this is fixed? I am using 1.6.6 still I can see this issue. Thanks in Advance.
