Configure SNMP Plug-In Port to the vRealize Orchestrator 8.x

In this post, we are going to look at how to configure the SNMP Plug-In port for vRealize Orchestrator 8.x. The SNMP port can be configured with a workflow for vRO 7 and 8, but since vRO 8 uses the Kubernetes infrastructure, this configuration must be Kubernetes based.

The following lines of code will help you.

  • Create a variable for the SNMP trap port. The ports open for SNMP traps are 81 to 32767.
SNMP_PORT=port_value
  • Create a Kubernetes NodePort service for the SMNP trap port over User Datagram Protocol (UDP).
kubectl -n prelude expose deployment vco-app --type=NodePort --name=vro-snmp-$SNMP_PORT --port=$SNMP_PORT --target-port=$SNMP_PORT --protocol=UDP 
  • Add the port to the NodePort service.
kubectl -n prelude patch svc vro-snmp-$SNMP_PORT --type='json' -p '[{"op":"replace","path":"/spec/ports/0/nodePort","value":'$SNMP_PORT'}]'
  • Patch the NodePort service, so the source IP address can connect to the vRealize Orchestrator pod.
kubectl -n prelude patch svc vro-snmp-$SNMP_PORT -p '{"spec":{"externalTrafficPolicy":"Local"}}'
  • Create the firewall rules for the configured SNMP port.
iptables -A INPUT -p udp -m udp --dport $SNMP_PORT -j ACCEPT

I found this post on the VMware Documentation site and it helped me with a workflow I developed in vRO 8.
