[release-4.22] OCPBUGS-100061: openstack: Reserve addresses for load balancer by openshift-cherrypick-robot · Pull Request #10725 · openshift/installer

openshift-cherrypick-robot · 2026-07-28T14:36:11Z

This is an automated cherry-pick of #10375

/assign openshift-ci-robot

When using Octavia, we use the .5 and .7 addresses on the first machine network for API and Ingress VIP, respectively [1]. However, we were not reserving these address when creating the network. This can result in an IP collision if another service happens to allocate one of these two IPs before the load balancer is created. This can happen if DHCP agents are running on the controller/network nodes, as each agent creates its own DHCP port on the subnet. The solution is to use allocation pools - which are designed exactly for this purpose - and configure one on the subnet we create (via CAPO). We reserve everything < .10 in case we need more addresses down the line. We were previously doing this with Terraform but lost this during the migration to CAPO. [1] `SetPlatformDefaults` in `pkg/types/openstack/defaults/platform.go` [2] https://github.com/openshift/installer/blob/release-4.20/data/data/openstack/masters/private-network.tf#L37-L43 Signed-off-by: Stephen Finucane <stephenfin@redhat.com>

/lgtm

as the bot said, we need to have the parent ticket something different than CLOSED and targeting 5.0.0. when the CI is happy, this should be ready to go.
