Preparing to Install OpenShift - Mirror OKD Images

Note: This is part of a series. Make sure you started here: Building a Portable Kubernetes Home Lab with OpenShift - OKD4

Create OpenShift image mirror

From your workstation, do the following:

1. Create the pull secret for Nexus. Use the username and password that we created with admin authority on the okd repository that we created.

   labcli --pull-secret
   

2. Set your cluster configuration for the latest OKD release:

   labcli --latest
   

3. Now mirror the OKD images into the local Nexus: This can take a while. Be patient

   labcli --mirror 
   

   Note: If you see X509 errors, and you are on a MacBook, you might have to open KeyChain and trust the Nexus cert. Then run the above command again.

   The final output should look something like:

   Success
   Update image:  nexus.my.awesome.lab:5001/okd:4.10.0-0.okd-2022-05-07-021833
   Mirror prefix: nexus.my.awesome.lab:5001/okd
   Mirror prefix: nexus.my.awesome.lab:5001/okd:4.10.0-0.okd-2022-05-07-021833
   
   To use the new mirrored repository to install, add the following section to the install-config.yaml:
   
   imageContentSources:
   - mirrors:
     - nexus.my.awesome.lab:5001/okd
     source: quay.io/openshift/okd
   - mirrors:
     - nexus.my.awesome.lab:5001/okd
     source: quay.io/openshift/okd-content
   
   
   To use the new mirrored repository for upgrades, use the following to create an ImageContentSourcePolicy:
   
   apiVersion: operator.openshift.io/v1alpha1
   kind: ImageContentSourcePolicy
   metadata:
     name: example
   spec:
     repositoryDigestMirrors:
     - mirrors:
       - nexus.my.awesome.lab:5001/okd
       source: quay.io/openshift/okd
     - mirrors:
       - nexus.my.awesome.lab:5001/okd
       source: quay.io/openshift/okd-content    
   

Now We are Ready To Install OpenShift
