capacity for more slaves

Looking at the load on our hypervisors I'm sure we can add more slaves to jenkins. Is there a documented procedure on how to add a new slave so anyone in the team can do it? -- Eyal Edri Associate Manager RHEV DevOps EMEA ENG Virtualization R&D Red Hat Israel phone: +972-9-7692018 irc: eedri

Hi, I added few more el7 slaves, there is a (relatively) new template 'centos72-jenkins-slave' in the Jenkins_CentOS cluster. iirc there was a discussion few months ago about our IPs limit, I think we're approaching that(there are 102 fixed addresses in foreman.phx.ovirt.org dhcpd server, and this

sure, added 4 more FC23 slaves, and on the way hit the IPs limit, had to remove some old unused testing VMs to release IPs. we have some useless leases there such as an IP for each template, though I'm not 100% sure if its safe to simply delete them from foreman (they are saved as templates in the

One possibility that will give us a lot of ips is using internal ones, though it will require a bit more configuration but now that the jenkins master is in phx I think it might be a good option David Caro El 13 may. 2016 7:57, Eyal Edri escribió: Please open a ticket in jira on extending the

Hello All. Then I suggest consider rolling out IPv6 for the slaves right away especially since it was declared a goal for oVirt 4. This can also simplify slaves management as we can use SLAC for IP assignment and can solve that DHCP update problems we had in foreman due to stale mac addresses etc.
