Description Pedro Amoedo 2019-09-24 15:46:49 UTC 
Document URLs:

Section Number and Name: 

Unknown

Describe the issue: 

Documentation mentions the following:

"All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require network in initramfs during boot to fetch Ignition config files from the Machine Config Server. During the initial boot, the machines require a DHCP server in order to establish a network connection to download their Ignition config files. After the initial boot, the machines can be configured to use static IP addresses."

Suggestions for improvement: 

AFAIK, the static IP addresses is an unsupported configuration and the documentation should reflect that with some note, otherwise, it should have examples or an external link to more detailed steps.

Master + 4.1+ branch removal of static IP line: https://github.com/openshift/openshift-docs/pull/17577

4.1-only branch addition of future support note per PM chat: https://github.com/openshift/openshift-docs/pull/17592

Chris Negus will be working on 4.2+ support docs for bare metal and Kathryn Alexander will be working on 4.2+ support docs for vSphere.
Comment 5 Alex Dellapenta 2019-10-25 11:50:37 UTC 
Not moving forward with https://github.com/openshift/openshift-docs/pull/17592, just the merged https://github.com/openshift/openshift-docs/pull/17577.

Updated 4.1 docs:

https://docs.openshift.com/container-platform/4.1/installing/installing_vsphere/installing-vsphere.html#network-connectivity_installing-vsphere

https://docs.openshift.com/container-platform/4.1/installing/installing_bare_metal/installing-bare-metal.html#network-connectivity_installing-bare-metal

Supported static IP docs will be added to 4.2+.
