Symptom

An ApigeeIssue with Reason AIS_INGRESS_CERT_EXPIREY is shown when viewing resources in the apigee namespace.

Error messages

After running kubectl -n apigee get apigeeissues, an error like the following is displayed: 

NAME                                         SEVERITY   REASON                     DOCUMENTATION                                                                          AGE

Possible causes

Cause Description
Ingress certificate is expiring soon The configured ingress certificate is expiring within 14 days.
Ingress certificate is expired The configured ingress certificate is expired.

Cause: Ingress certificate is expiring soon

The ingress certificate stored in the Kubernetes secret referenced by an ApigeeRouteConfig is expiring within the next 14 days.

Diagnosis

Run the following command: 

kubectl -n apigee describe apigeeissue ISSUE_NAME

Where ISSUE_NAME is the name of the issue. For example, ingress-cert-expiring-soon-my-org-my-virtualhost.

The output should look similar to the following:

  Details:        Ingress certificate in secret "my-org-my-virtualhost" for ApigeeRouteConfig "my-org-my-virtualhost" is expiring in 5.409373245s at 2024-03-11 19:04:12 +0000 UTC

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

Resolution

  1. Use kubectl describe to display the name of the ApigeeRouteConfig which has the ingress cert which is expiring soon: 

    kubectl -n apigee describe apigeeissue ISSUE_NAME

    Where ISSUE_NAME is the name of the issue. For example, ingress-cert-expiring-soon-my-org-my-virtualhost.

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

  2. 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.

  3. Find the corresponding virtualhost in your overrides.yaml.

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

  4. Update the certificate and key listed in the sslCertPath and sslKeyPath files.

  5. Apply the changes to the virtualhost:

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

Cause: Ingress certificate is expired

The ingress 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, ingress-cert-expired-my-org-my-virtualhost.

Something similar to the following is returned:

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

Resolution

  1. Use kubectl describe to display the name of the ApigeeRouteConfig which has the expired ingress cert: 

    kubectl -n apigee describe apigeeissue ISSUE_NAME

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

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

  2. 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.

  3. Find the corresponding virtualhost in your overrides.yaml.

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

  4. Update the certificate and key listed in the sslCertPath and sslKeyPath files.

  5. Apply the changes 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:

  1. The Google Cloud Project ID.
  2. The name of the Apigee hybrid organization.
  3. The Spec.Details field of the ApigeeIssue.
  4. (optional) Files referenced by sslCertPath and sslKeyPath for the affected virtualhost.
