initially, i had a 4 node test cluster and i encountered similar issues. then, i increased the cluster size and my problems were resolved. my current cluster size is as follows: 8 worker nodes w/ 8 vcpu, 16g ram, 120g disk on each; 1 controller node w/ 4 vcpu, 8g ram, 40g ram. i'm able to deploy onap (istanbul release) on this cluster successfully. hope this helps!
i use 4 vms to deploy onap (minimal onap). Each vm has 64 G ram and 200 G disk.
But after "helm deploy ..." there are always some pods that keep failing and restarting.
For example
the readiness container fails many times and restarts many times. I have no idea what goes wrong.
Could you give me some possible solution to check what goes wrong?
