Step 9: Install cert-manager

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

Install cert-manager

  1. Use the following command to install cert-manager v1.17.4 from GitHub. 
     kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.17.4/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
  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 for cert-manager, cert-manager-cainjector, and cert-manager-webhook.

Summary

You now have cert-manager installed, and you are ready to install the Apigee hybrid custom resource definitions (CRDs).
