Step 8: Install cert-manager

This step explains how to download and install cert-manager, required for Apigee hybrid to operate.

Installations on Google Distributed Cloud

You do not need to install cert-manager if you are performing a fresh installation on one of the following on-premises platforms:

Google Distributed Cloud (software only) on VMware
Google Distributed Cloud (software only) on bare metal

Google Distributed Cloud comes with its own version of cert-manager. Apigee can use this Distributed Cloud version of cert-manager. If it is installed in a namespace other than cert-manager, you will need to include the namespace with the certManager.namespace property in your overrides file. For more information about Google Distributed Cloud and cert-manager, see Conflicting cert-manager installation.

Installations on OpenShift

If you are installing Apigee hybrid on OpenShift, install cert-manager by following the instructions in Installation in the cert-manager documentation.

See a Known Issue about cert-manager version 1.10 on OpenShift.

Install cert-manager

Use the following command to install cert-manager v1.15.1 from GitHub.

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.15.1/cert-manager.yaml

You should see a response that the cert-manager namespace and several cert-manager resources have been created. For example:

customresourcedefinition.apiextensions.k8s.io/certificaterequests.cert-manager.io configured
customresourcedefinition.apiextensions.k8s.io/certificates.cert-manager.io configured
...
mutatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configured
validatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configured

Use the following command to verify the successful creation of cert-manager namespace and its corresponding components:

kubectl get all -n cert-manager -o wide

Your output should be similar to the following example. You should see pods for cert-manager, cert-manager-cainjector, and cert-manager-webhook.
