Dear Community Members,

We have deployed ONAP(Istanbul version) with minimum components required for 
'Network Slicing Use case' in a single node(Single AWS VM with 64 CPU, 128 RAM 
and 400 disk).

We used following file to deploy ONAP.
https://github.com/onap/oom/blob/istanbul/kubernetes/onap/resources/overrides/onap-5g-network-slicing.yaml

and Enabled following components in above file.

cps:
enabled: true
sniro-emulator:
enabled: true
sdnc:
enabled: true
replicaCount: 1
mysql:
replicaCount: 1

After deploy ONAP, 'onap-sdnc-0' stuck into 'Init:0/5' status.

After describe pod, we got following output.

kubectl describe pods onap-sdnc-0 -n onap

Enough memory is available in a single node. So there is no memory issue.

We are not getting how to solve below error.
failed for volume "certmanager-certs-volume-0" : secret "onap-sdnc-secret-0" 
not found

Could you please help us to sort out this issue?

Regards
Ganesh Mane
