## OpenShift4 pull-secret:

1. Download your pull-secret from [console.redhat.com](https://console.redhat.com/openshift/install/aws/installer-provisioned)
   - click on “Download Pull Secret”.  Save it somewhere, e.g. ~/some-dir/pull-secret
2. Add the apps.ci auth to pull-secret! _internal OpenShift developers only_
   - Obtain an API token by visiting https://oauth-openshift.apps.ci.l2s4.p1.openshiftapps.com/oauth/token/request 
     copy the oc login cmd and paste in terminal to login to the ci cluster, then run this:
   - `$ oc registry login --to ~/some-dir/pull-secret`    
   This will append the auth from  registry.ci.openshift.org to your cloud.openshift.com pull-secret but it will also   
   make the pull-secret multi-line.
