HOWTO
Add memory
$ crc stop
INFO Stopping kubelet and all containers...
INFO Stopping the instance, this may take a few minutes...
Stopped the instance
dave@fedora:~/Downloads$ crc config set memory 14336
Changes to configuration property 'memory' are only applied when the CRC instance is started.
If you already have a running CRC instance, then for this configuration change to take effect, stop the CRC instance with 'crc stop' and restart it with 'crc start'.

Thanks for sharing this guide! The step where you bump CRC memory before enabling monitoring was a real lifesaver—I’ve hit issues in the past when I forgot that part. Seeing the full pod manifest spelled out makes it clear how much we rely on YAML to keep everything consistent. Curious if you’ve tested this with larger workloads in CRC?
