Description Evgheni Dereveanchin 2015-09-08 05:27:51 EDT
Document URL: 
Section Number and Name: 
  14.2.1. Configuring a Highly-available Routing Service
  14.2.2. Configuring a Highly-availabile Network Service
Describe the issue: 
 --virtual-ips is not described. It proposes a range "" but does not describe if this should be a routable IP, internal IP, node's IP or something else
Suggestions for improvement: 
 remove confusion by describing what this IP range can be

Seems there's a section about Virtual IPs from 3.4 onwards:


I can backport this into the 3.0 -> 3.3 docs. But in your opinion, is this enough information for this BZ? Would there be anything more information needed?

I can also add footnotes to the procedures if you think it's needed. Much like the example in the "Deploy IP Failover Pod" section here:


(Scroll down a little).

Please let me know if I'm off the mark and it requires more efforts.

Hi Brice,

This looks good to me. Feel free to decide if this needs to be backported to older version documentation: it's important for new deployments and those typically use the latest version.
Comment 6 Eric Rich 2017-07-19 11:22:25 EDT
How far back is QE testing these procedures? IMO thats how far back we should backport this.
Comment 7 brice 2017-07-19 23:46:35 EDT
Eric, I'm not sure if I can answer that question. I can see why the information might be needed though.

Meng Bo, do you know if this section of the docs would be tested? Wondering how far back the changes would be needed in the 3.0 -> 3.3 documentation. Thanks!
Comment 8 Meng Bo 2017-08-01 01:44:17 EDT
Hi, the requirements described in 3.5 doc[1] are also available for all old versions of OCP. We can backport it.

Comment 9 brice 2017-08-02 01:45:00 EDT
OK. I added a section about virtual IPs directly onto the 3.0-3.3 branches. You can see it here:


(I added the same to all four branches, so I won't link them all.)

It's essentially the paragraph from the 3.4 -> Current docs, but I added the environment variable from the table. Evgheni, is there anything more you think is needed for this BZ?
Comment 10 Evgheni Dereveanchin 2017-08-03 04:15:33 EDT
Looks OK to me, thank you for backporting it.
Comment 11 brice 2017-08-03 23:22:29 EDT
Great! Thanks, Evgheni. I'll move this BZ to complete.
