<div dir="ltr">For posterity, I wanted to update this thread in the hope it may benefit others out in the community. <div><br></div><div>We reached out to Evolveum on this issue and they found an issue with clustering using ip addresses in certain networking scenarios common with containerization networks. A Jira was created here: <a href="https://jira.evolveum.com/browse/MID-8107">https://jira.evolveum.com/browse/MID-8107</a> which is related to MID-7210.<div><br></div><div>Evolveum has identified a work-around: </div><div><br></div><div>------ Workaround ------<br><br>In case the containers are located all the time on the same host with the static IPs there is a way how to "inform" the registration process about the IP. It is inspired by the router configuration approach (networking) and I have tested it is working on alpine based image (at least for the propagation part).<br><br>------ Idea ------<br><br>The propagated IPs are taken from all the presented interfaces including lo (only the loopback addresses are ignored). We can assign IP "alias" to the loop interface with "full bit mask" (/32 in case of IPv4 and /128 in case of IPv6). This way the IP is known to the system but it is causing no impact on routing information. Next to it default route contain the "src" attribute set so this IP alias impacting nothing next to the situation that it is simply exists...<br><br>------ Requirements ------<br><br>The container by default does not have the permission to set the networking parameters. To grant this permission it has to be explicitly set :<br><br> --cap-add NET_ADMIN<br><br>in the context it would be : "podman run --cap-add NET_ADMIN -p 8080:8080 ... evolveum/midpoint:4.5-alpine"<br><br>Next to it the IP have to be set before the midPoint start. The most suitable way is to set it by "command" (in case you are running evolveum/midpoint:4.5-alpine image where the "default" commant is "/opt/midpoint/bin/midpoint.sh container"):<br><br> /bin/bash -c "/sbin/ip a a <a href="http://129.22.104.212/32">129.22.104.212/32</a> dev lo ; /opt/midpoint/bin/midpoint.sh container"<br><br>------ Example ------<br><br>podman run --cap-add NET_ADMIN -p 8080:8080 ... evolveum/midpoint:4.5-alpine /bin/bash -c "/sbin/ip a a <a href="http://129.22.104.212/32">129.22.104.212/32</a> dev lo ; /opt/midpoint/bin/midpoint.sh container"<br><br>All the rest parameters (...) should be the same as you are using now. The result would be like :<br><br> midpoint-d-1 : fe80:0:0:0:ac6a:efff:fe03:d82f ; 10.88.0.5 ; 129.22.104.212<br><br>With this workaround the cluster would be able to run as expected.<br><br>------ Potential issue with the workaround ------<br><br> - can't be more containers on the same node without explicit tuning of the network (like more IP to NAT the source IP to)<br> - the host IP can't change or the update process has to be found and set<br><br>--------------------<br></div><div><br></div><div><br></div><div><br><div>Thanks,</div><div>Paul Spaude</div><div><br></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 24, 2022 at 7:46 AM Samuel Harmon via midPoint <<a href="mailto:midpoint@lists.evolveum.com">midpoint@lists.evolveum.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">In hopes that this issue was the same as described in MID-7210 (it seems very similar to the issue described there, especially given that I'm running my nodes in containers), I upgraded my nodes to midPoint 4.5.
