Optional: Cleaning Up Disk Space After Upgrading to 2.1.0

As part of the Systemstate improvements in 2.1.0, the resourceStates NATS bucket is no longer used. If you want to save disk space, you can delete this bucket.

• To clean up disk space, run the following:

Replace ${NAMESPACE} with your Connectware namespace (e.g., cybus).

kubectl debug -it \
  -n ${NAMESPACE} $(kubectl get pod -n ${NAMESPACE} -lapp=system-control-server -o name) \
 --image=registry.cybus.io/cybus/connectware-toolkit:1.4.0 \
 --target=system-control-server --profile general \
 -- bash -c 'source /proc/1/root/connectware_certs/env-1.0.sh && nats -s nats:4222 --user cybus_auth --password $CYBUS_NATS_AUTH_PASSWORD --tlscert=/proc/1/root/connectware_certs/cybus_client.crt --tlskey=/proc/1/root/connectware_certs/cybus_client.key --tlsca=/proc/1/root/connectware_certs/cybus_combined_ca.crt kv del resourceStates -f'
