Review comment:
```suggestion
trimmed_pod_id = pod_id[:MAX_LABEL_LEN].rstrip('-') # Strip
trailing '-' as it cant be followed by '.'
safe_pod_id = f"{trimmed_pod_id}.{safe_uuid}"
```
Maybe? Either way, your comment is wrong as it only removes trailing
dashes, and occurrences has a typo.
What about the '..' case (and more, maybe trimming until the last char is
a-z0-9)?
