remove oc cluster up in favor of openshift/installer

[deads2k]

We are focusing our efforts on a fast, easy to use installer that will drive installation and configuration for all flavors of user instead of trying to segregate users into different classes. Doing this will give platform developers one target and should improve reliability, consistency, and velocity. This removes the old oc cluster up flow. Long live openshift-installer.

As openshift-installer doesn't yet support xhyve/virtualbox, that will then impact the developer's experience ....

[gustavocoding]

Looking at the openshift installer, it currently supports AWS and openstack and the libvirt setup is detailed here https://github.com/openshift/installer/blob/master/docs/dev/libvirt-howto.md, so far from being trivial as oc cluster up. Is a replacement for oc cluster up planned?

[sspeiche]

oc cluster up was a tool for use by the developers of OpenShift itself, there will exist a streamlined localized installer like minishift. Instead of having multiple competing but different options, we are aligning around the installer and using new version of minishift to provide the experience like oc cluster up

[gustavocoding]

Thanks @sspeiche, looking forward to it.

Out of curiosity, now that 'oc cluster up' is dead and developers cannot use it anymore, what are they using now? Docker In Docker cluster or they all migrated to virtualization?
