Follow Google's instructions to provision your cluster.
We recommend using an nginx ingress when running OpenWhisk on GKE.
According to your nginx ingress settings you can define a value of your choice. Check the official Google Cloud documentation here: https://cloud.google.com/kubernetes-engine/docs/tutorials/configuring-domain-name-static-ip. As stated you can create a domain of the type: openwhisk.<your-chosen-dns-name>.com
You can choose to create a tls secret for that and provide values for and in base64.
To generate the values for and you can use the openssl tool:
openssl req -newkey rsa:2048 -nodes -keyout tls.key -x509 -days 365 -out tls.crt cat tls.key | base64 cat tls.crt | base64
Now define mycluster.yaml
as below:
whisk: ingress: apiHostName: <domain> apiHostPort: 443 apiHostProto: https type: Standard domain: <domain> tls: enabled: true secretenabled: true createsecret: true secretname: openwhisk-ingress-tls-secret secrettype: kubernetes.io/tls crt: <tlscrt> key: <tlskey> annotations: kubernetes.io/ingress.class: nginx kubernetes.io/tls-acme: true nginx.ingress.kubernetes.io/proxy-body-size: 0
