Comment 2 Johnny Liu 2018-05-15 06:18:58 UTC

Seem like this is intended introduced by https://github.com/openshift/openshift-ansible/pull/8329, QE open this bug want to have a confirm, if we only support:
1. for a install on RHEL, only rpm install method
2. for a install on AH, only node system container install method


If yes, we need turn this bug into doc bug to notify customer.

Comment 3 Scott Dodson 2018-05-15 12:48:58 UTC

Right, we only support RPM based installs on normal RHEL. We're going to be doing an audit of documentation to clarify this.

Comment 4 Vikram Goyal 2018-05-15 12:55:49 UTC

Scott - we already have a note here about this: https://docs.openshift.com/container-platform/3.9/install_config/install/advanced_install.html#overview

Is there more we need to update/add?

Comment 5 Scott Dodson 2018-05-15 19:08:06 UTC

Vikram,

That note looks to deal with where you're running the installer. Whereas this bug relates to the fact that in 3.10 we only support two options. RPM based installs on RHEL and System Container based installs on Atomic Host.

LGTM, leave some comments about etcd in the PR, but that is another issue, verify this bug.
