Description Yossi Boaron 2020-09-21 13:00:07 UTC

Description of problem:

In current implementation, master nodes should specify the bootstrap IP address as one of their Keepalived peers.
The Bootstrap IP being retrieved by communicating with a TCP server runs on the bootstrap node, this server is listening on port number 64444.


Version-Release number of selected component (if applicable):


How reproducible:
Block port #64444 between nodes.

Steps to Reproduce:
1.Block port #64444 between nodes.
2.Run IPI baremetal deployment
3.

Actual results:
Deployment fails

Expected results:
Deployment should be succeed.

Comment 1 Michelle Krejci 2020-09-21 17:22:54 UTC

Could you clarify: we expect that port 64444 needs to be unblocked in order for deployment to occur. Could you provide some more information for the use case on why the behavior should be different?

Comment 2 Yossi Boaron 2020-09-22 08:01:34 UTC

Well, it isn't a clear case of bug it's more an enhancement, when we introduced the new Keepalived method [1], we got comments asking to remove the TCP server running on the bootstrap node.

I will close this BZ
