## Assumption
Assumes you are using the default L7 GLBC ingress controller. default for GKE cluster.

## create a certficate 
```
gcloud beta compute ssl-certificates create ci-example --domains ci.example.com
```
## list a certifcate
```
gcloud beta compute ssl-certificates list
```
## checking certificate provisoning status
```
gcloud beta compute ssl-certificates describe ci-example
```
Please note with a correct configuration the total time for provisioning certificates is likely to take from 30 to 60 minutes.

## modify the ingress
```
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ci
  namespace: ci
  annotations:
    ingress.gcp.kubernetes.io/pre-shared-cert: 'ci-example'
spec:
  backend:
    serviceName: jenkins-ui
    servicePort: 8080
```

`ingress.gcp.kubernetes.io/pre-shared-cert` is used by `ingress-gce`
