You are currently viewing version 1.11 of the Apigee hybrid documentation.This version is end of life. You should upgrade to a newer version. For more information, seeSupported versions.

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

Installations on Anthos

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

• Anthos on-premises - (VMware)
• Anthos on Bare Metal

Anthos comes with its own version of cert-manager. Apigee can use this Anthos version of cert-manager. If it is installed in a namespace other thancert-manager, you will need to include the namespace with thecertManager.namespace property in your overrides file. For more information about Anthos and cert-manager, seeConflicting cert-manager installation.

Installations on OpenShift

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

See aKnown Issue about cert-manager version 1.10 on OpenShift.

Install cert-manager

1. Use the following command to install cert-manager v1.11.1 from GitHub.

   kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.11.1/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 configuredcustomresourcedefinition.apiextensions.k8s.io/certificates.cert-manager.io configured...mutatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configuredvalidatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configured

2. 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 forcert-manager,cert-manager-cainjector, andcert-manager-webhook.
