Get error message "Internal error occurred: failed calling webhook " while restarting cluster but cluster is up after waiting sometime

[yshashix]

After rebooting Ubuntu machine , I don't see auto-restart of OISP cluster so when I tried to re-start cluster using command /platform-launcher/util$ sudo bash ./restart-cluster.sh, I receive error like below but while checking pods of webhook, it seems running.

HW: Intel corei7

OS: Ubuntu 18.04
Used with docker username

The error message is as below

mutatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook created
validatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook created
Waiting for cert-manager web-hook to come up

Cert-manager Webhook ready! Now applying clusterissuer for self-cert.
Error from server (InternalError): error when creating "../kubernetes/cert-manager/clusterissuer-self-cert.yaml": Internal error occurred: failed calling webhook "webhook.cert-manager.io": Post https://cert-manager-webhook.cert-manager.svc:443/mutate?timeout=30s: context deadline exceeded
Operators installed successfully.
Ready to deploy OISP
ieitank@ieitank:~/platform-launcher/util$

but webhook is applied:
ieitank@ieitank:/platform-launcher/util$ kubectl get po -n cert-manager
NAME READY STATUS RESTARTS AGE
cert-manager-cainjector-789955d9b7-vqx8c 1/1 Running 0 2m47s

cert-manager-webhook-64869c4997-h9l62 1/1 Running 0 2m47s
ieitank@ieitank:/platform-launcher/util$

Even sometime ./delpoy_operator.sh is not found still message for OISP ready is displayed, which is just misinformation.

after running sudo ./restart-cluster.sh

Set routing between docker and host for K3S

Soln:

It might be that script has some message o/p error so need to look in scripts
