The contents of Spec.Details explains the name of the ApigeeRouteConfig that refers to the Kubernetes secret containing the ingress mTLS CA certificate which is expiring soon.

Resolution

Use kubectl describe to display the name of the ApigeeRouteConfig which has the ingress mTLS CA cert which is expiring soon:
```
kubectl -n apigee describe apigeeissue ISSUE_NAME 
```
Where ISSUE_NAME is the name of the issue. For example, ca-cert-expiring-soon-my-org-my-virtualhost .

In this example, the ApigeeRouteConfig my-org-my-virtualhost is referencing the secret my-org-my-virtualhost .
Determine the virtualhost name from the ApigeeRouteConfig .

The ApigeeRouteConfig 's name is in the format: <Apigee organization>-<virtualhost name> .

In this example, my-org is the Apigee organization and the virtualhost name is my-virtualhost .

Find the corresponding virtualhost in your overrides.yaml .

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

Update the CA certificate listed in the caCertPath file.

Apply the change to the virtualhost:

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

Cause: Ingress mTLS CA certificate is expired

The ingress mTLS CA certificate stored in the Kubernetes secret referenced by an ApigeeRouteConfig has expired.

Diagnosis

Run the following command:

kubectl -n apigee describe apigeeissue ISSUE_NAME

Where ISSUE_NAME is the name of the issue. For example, ca-cert-expired-my-org-my-virtualhost .

The output should look similar to the following:

 Name 
 : 
  
 ca

The contents of Spec.Details explains the name of the ApigeeRouteConfig that refers to the Kubernetes secret containing the ingress mTLS CA certificate which has expired.

Resolution

Use kubectl describe to display the name of the ApigeeRouteConfig which has the expired ingress mTLS CA cert:
```
kubectl -n apigee describe apigeeissue ISSUE_NAME 
```
Where ISSUE_NAME is the name of the issue. For example, ca-cert-expired-my-org-my-virtualhost .

In this example, the ApigeeRouteConfig my-org-my-virtualhost is referencing the secret my-org-my-virtualhost .
Determine the virtualhost name from the ApigeeRouteConfig .

The ApigeeRouteConfig 's name is in the format: <Apigee organization>-<virtualhost name> .

In this example, my-org is the Apigee organization and the virtualhost name is my-virtualhost .

Find the corresponding virtualhost in your overrides.yaml .

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

Update the CA certificate listed in the caCertPath file.

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 :

The Google Cloud Project ID.
The name of the Apigee hybrid organization.
The Spec.Details field of the ApigeeIssue .
(optional) File referenced by caCertPath for the affected virtualhost.
