Cause: Virtualhost is missing ingress selector

A virtualhost declared in overrides.yaml does not have the ingress selector field set.

Diagnosis

Run the following command:

kubectl -n apigee describe apigeeissue ISSUE_NAME

Where ISSUE_NAME is the name of the issue. For example, vhost-missing-selector-my-org-my-virtualhost.

The output should look similar to the following:

Spec:
  Details:        Expected ingress selector in ApigeeRouteConfig "my-org-my-virtualhost". Environment Group/virtual host "my-virtualhost" is missing an ingress selector.

The contents of Spec.Details explains the name of the virtualhost which is missing the ingress selector.

Resolution

Use kubectl describe to check the details of the issue:
```
kubectl -n apigee describe apigeeissue ISSUE_NAME
```
Where ISSUE_NAME is the name of the issue. For example, vhost-missing-selector-my-org-my-virtualhost.
Determine the virtualhost name from the Spec.Details field.

In this example, the virtualhost is called my-virtualhost.

Find the corresponding virtualhost in your overrides.yaml.

virtualhosts:
...
- name: my-virtualhost
  sslCertPath: ./certs/vhost.pem
  sslKeyPath: ./certs/vhost.key
...

Update the virtualhost and add the ingress selector:

virtualhosts:
...
- name: my-virtualhost
  selector:
    app: apigee-ingressgateway
  sslCertPath: ./certs/vhost.pem
  sslKeyPath: ./certs/vhost.key
...

Apply the change to the virtualhost:

helm upgrade ENV_GROUP_NAME apigee-virtualhost/ \
  --namespace apigee \
  --set envgroup=ENV_GROUP_NAME \
  -f overrides.yaml

Must gather diagnostic information

If the problem persists even after following the above instructions, gather the following diagnostic information and then contact Google Cloud Customer Care:
