# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

How to configure max pods for the SUSE Rancher Kubernetes distributions

Considerations when Increasing the Max Pod Count

Changing the max-pods on an active cluster with workloads is generally a safe procedure when target number of max-pods is <=250. When the goal number of max-pods is >250, the additional considerations mentioned above require a deletion of all currently running pods.

If increasing max-pods to >250, there are additional considerations and changes required. The in-cluster IP management configuration needs to be modified as the default is a /16 split into one /24 for each node in the cluster. This comes to a limit of about 256 nodes with roughly 253 pods per node.

--max-pods int32 Default: 110
