Assisted Installer for OpenShift is now generally available
Although clusters created with the Assisted Installer for OpenShift have been and continue to be maintained, the hosted Assisted Installer has remained a Technology Preview until now.
What is the OpenShift Assisted Installer and how does it work?
The Red Hat Hybrid Cloud Console’s OpenShift Assisted Installer makes it simple to deploy OpenShift on your nodes. The installer is a managed service for bare metal OpenShift cluster installation (though not restricted to). It does not require a bootstrap node or the installation of Red Hat CoreOS on your nodes prior to installing the cluster; instead, you simply enter your cluster’s information into the web UI and boot your nodes with an ISO image given (see demo below).
It has been accessible as a Technology Preview for several versions, and we have received excellent user feedback during that time. The number of clusters deployed and adoption are both increasing on a daily basis.
