Aai-cassandra is a statefulset.
So, we have to overwrite the value of replicaCount: 1 in
aai/charts/aai-cassandra/values.yaml
I generally deploy each component individually because of setup and resource
constraints.
If you deploy individual components then override something like below
Below is just an example in my setup. You may want to fine tune Probe values
based on resources in your setup
global:
repository: xx.xx.xx.xx:5000
pullPolicy: IfNotPresent
flavor: unlimited
liveness:
initialDelaySeconds: 120
aai-cassandra:
replicaCount: 1
aai-data-router:
liveness:
initialDelaySeconds: 120
aai-sparky-be:
liveness:
initialDelaySeconds: 120
aai-spike:
liveness:
initialDelaySeconds: 120
aai-champ:
liveness:
initialDelaySeconds: 120
readiness:
initialDelaySeconds: 120
aai-resources:
readiness:
initialDelaySeconds: 120
If you are deploying all ONAP components together (using helm deploy plugin)
then you may have to do something like below to override
global:
repository: xx.xx.xx.xx:5000
pullPolicy: IfNotPresent
flavor: unlimited
aai:
liveness:
initialDelaySeconds: 120
aai-cassandra:
replicaCount: 1
aai-data-router:
liveness:
initialDelaySeconds: 120
aai-sparky-be:
liveness:
initialDelaySeconds: 120
aai-spike:
liveness:
initialDelaySeconds: 120
aai-champ:
liveness:
initialDelaySeconds: 120
readiness:
initialDelaySeconds: 120
aai-resources:
readiness:
initialDelaySeconds: 120

Perhaps there is some adjustment to the Helm charts needed, because the
aai-cassandra container fails claiming it needs 2 nodes. Granted, I'm using
Casablanca code. Are you aware of any tweaks needed to the charts?

Hi DeWayne,
I don’t think there is such requirement. You can deploy the whole ONAP in
single HP or DELL gen9 v4 or above server (having 256GB RAM, 56 CPU (with hyper
threading)). All you need to do is increase the --max-pods in kubelet. I did
this with Rancher and kubeadm and able to deploy ONAP successfully in single
server.
Attached the rancher POST call for reference.
Also I did test ONAP Casablanca with helm v2.12.3 and kubelet version 1.13.4 as
well. With latest kubeadm you need to adjust the value of maxPods in
“/var/lib/kubelet/config.yaml” and restart the kubelet
Coming to taints, affinities and nodeSelector fields unless you specify ONAP
charts doesn’t have these enabled as default.
Thanks,
Kranthi

Subject: [onap-discuss] OOM: K8S deployment minimum nodes
Has anyone established the minimum number of compute nodes that ONAP can run
on (in a K8S deployment)? Not counting Rancher or the Kubernetes master. I
know it's at least 2, but was wonder if anyone had established the minimum.
I'm not talking about resource limitations, I'm talking about actual
deployments or pods having taints or affinities that require a certain number
of nodes.
Thanks,
DeWayne
