Equinix or MOSK clusters update fails with stuck kubelet¶
The Equinix Metal managed clusters and managed clusters running MOSK may fail to update to the latest Cluster release with kubelet being stuck and reporting authorization errors.
The cluster is affected by the issue if you see the Failed to make webhook authorizer request: context canceled error in the kubelet logs:
docker logs ucp-kubelet --since 5m 2>&1 | grep 'Failed to make webhook authorizer request: context canceled'
To apply the issue resolution, restart the

ctr -n com.docker.ucp snapshot rm ucp-kubelet docker rm -f ucp-kubelet
Ignore failures in the output of the first command, if any.
