Description RHCOS Bug Bot 2021-10-07 19:32:04 UTC

Backport the fix for bug 2011956 to 4.9.

Comment 1 Micah Abbott 2021-10-08 19:02:22 UTC

This tracker is a bit confusing; the 4.9 version of the kubelet BZ is https://bugzilla.redhat.com/show_bug.cgi?id=2011815

Which links to https://github.com/openshift/kubernetes/pull/1009

The fixed kubelet is built from 894a78b5538c3e96d7bdfabfa8b41430cbd6811e or newer

In the most recent RHCOS 4.9 build for x86_64 (49.84.202110081407-0), it contains `openshift-hyperkube-4.9.0-202110080828.p0.git.894a78b.assembly.stream.el8`

The short commit id in the NVR (894a78b) indicates that this is built from the correct commit.

Additionally, an inspection of the `kubelet` itself on a running RHCOS node confirms the same:
