[release-4.22] OCPBUGS-119956: Allow per-node OVN encap IP override via env-overrides by SchSeba · Pull Request #3148 · openshift/cluster-network-operator

SchSeba · 2026-09-03T10:58:28Z

Teach the ovnkube node startup wrapper to source OVN_ENCAP_IP from the
per-node env-overrides ConfigMap and pass it to ovnkube as --encap-ip.
Normalize whitespace in the override so single-IP and comma-separated
encap IP values are passed safely as one shell argument, and keep
coverage for the optional env-overrides mount used for day2 updates.

Manual cherry-pick because #3147 failed.
Had to drop DpuNodeLeaseRenewInterval and DpuNodeLeaseDuration from the
env-overrides DaemonSet test, bootstrap fields do not exist on
the release-4.22 OVNConfigBoostrapResult API.

waiting on https://redhat-internal.slack.com/archives/CDCP2LA9L/p1788854122124259?thread_ts=1778514163.567789&cid=CDCP2LA9L and https://redhat-internal.slack.com/archives/CDCP2LA9L/p1788854142187619?thread_ts=1778514163.567789&cid=CDCP2LA9L

all information on a specific PR's backport should be on the PR, (eg any conflicts? why wasn't cherry-pick bot used, any new code changes etc, and mostly importantly use -x to cherry-pick from merged commit on newer branches) -same ask goes for 4.21 and 4.20 PRs and all backport PRs really
