I'm trying to get KNative to be able to create services on my Multipass VM with MacOS as the host OS and I am using MicroK8S. I have DNS enabled and I am using metallb as my ingress controller. I have also changed Multipass to use hyperkit instead of VirtualBox. I don't know what's not been configured or missconfigured. The error I get when I try to create a new service is pasted below:
ubuntu@uncommon-javelin:~/sandbox/sessions/serverless_k8s/yaml$ kn service create nginx --image nginx --port 80 Error: Internal error occurred: failed calling webhook "webhook.serving.knative.dev": failed to call webhook: Post "https://webhook.knative-serving.svc:443/defaulting?timeout=10s": dial tcp 10.152.183.167:443: connect: connection refused Run 'kn --help' for usage
When I ping that IP, it times out. So it seems like that IP address is either locked down or doesn't exist. Port 443 is configured in my ingress-service.yaml file
apiVersion: v1
kind: Service
metadata:
name: ingress
namespace: ingress
spec:
selector:
name: nginx-ingress-microk8s
type: LoadBalancer
ports:
- name: http
protocol: TCP
port: 80
targetPort: 80
- name: https
protocol: TCP
port: 443
targetPort: 443
And here is what I have configured for metallb address pool
apiVersion: v1
kind: Service
metadata:
name: test-service
annotations:
metallb.univers.tf/address-pool: custom-addresspool
spec:
selector:
name: nginx
type: LoadBalancer
ports:
- protocol: TCP
port: 80
targetPort: 80
And here's another address-pool.yaml I have configured for my cluster, I'm pretty sure that I have either something networking misconfigured or I'm missing a configuration somewhere.
apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
name: custom-addresspool
namespace: metallb-system
spec:
addresses:
- 192.168.1.1-192.168.1.100
Knative uses validating admission webhooks to ensure that the resources in the cluster are valid. It seems like the Knative webhooks are not running on your cluster, but the validatingwebhookconfiguration has been created, as has the service in front of the webhook (the IP in the error message is a ClusterIP of a Kubernetes service on your cluster).
I'd look at the webhook pods in the knative-serving namespace for more details.
