Installing GitOps Operator Candidate in Disconnected Cluster

Installing GitOps Operator Candidate in Disconnected Cluster

0. Install the latest "oc" openshift-client and opm tool  

   https://mirror.openshift.com/pub/openshift-v4/clients/ocp-dev-preview/latest-4.7/

1. Login as kubeadmin

2. Connect to VPN

(skip) 2.1. Disable default operator indices 

    $ oc patch OperatorHub cluster --type json -p '[{"op": "add", "path": "/spec/disableAllDefaultSources",
"value": true}]'
   
3. Extract pull secret of mirror registry to "authfile"

   $ oc get secrets pull-secret -n openshift-config -o template='{{index .data ".dockerconfigjson"}}' | base64 -d > authfile

   authfile looks like:
   {
        "auths": {
            "ec2-3-137-162-14.us-east-2.compute.amazonaws.com:5000": {
               "auth": "xxxxxxxxxxxxx"
            }
        }
  }

  ec2-3-137-162-14.us-east-2.compute.amazonaws.com:5000 is the <ec2 mirror registry>

 4. Add auth tokens of quay.io, "registry.redhat.io" to <authfile>

 5. Disable tls verify for ec2 mirror

   $ oc edit image.config.openshift.io/cluster
   
   and the following under spec.  Note: <ec2 mirror registry> without port just the host

spec:
  allowedRegistriesForImport:
  - domainName: <ec2 mirror registry>
    insecure: true
  registrySources:
    insecureRegistries:
    - <ec2 mirror registry>
    
6. Mirror (the mirrored index in quay.io) index/catalog to mirror registry

  $ oc adm catalog mirror -a authfile --insecure=true \
    quay.io/wtam/test-index@sha256:6b91e91c14ef7accd4446016b396ff2f6943b3a184ad61fa1d16b3d7e2278335 <ec2 mirror registry> 

  When the above mirror command is done, it generates 3 files in a sub-directory
  
  ── manifests-test-index-1612951393
    ├── catalogSource.yaml
    ├── imageContentSourcePolicy.yaml
    └── mapping.txt

 7.oc apply -f manifests-test-index-1612951393l
 
 
 Done.  Now go to the dev console

4. Add auth tokens of quay.io, "registry.redhat.io" to

$ podman login quay.io --authfile authfile --username user_name --password password
Login Succeeded!

$ podman login registry.redhat.io --authfile authfile --username user_name --password password
Login Succeeded!

$ cat authfile
{
"auths": {
":5000": {
"auth": ""
},
"quay.io": {
"auth": "******"
},
"registry.redhat.io": {
"auth": "*************************************"
}
}
}
