Edge node has been OOMKilled 51 times in 5 days (~1 every 2.4h) on a
1Gi memory limit. Chrome runs maxSessions=2 on the same 1Gi cap and
was idling at 684Mi — first concurrent session pushing the node to
~900Mi+ would be the next OOM. Hub was running at 766Mi against a 1Gi
limit (75%); no recent restarts but no headroom either.
Firefox node has been running at 2Gi memory limit for 9 days with
zero restarts — that is the right size for a Selenium 4.27 browser
node under our session profile (screen recording sidecar + 1080p
rendering + page captures). Match it.
Changes:
- Hub: limit 1Gi -> 1.5Gi, request 512Mi -> 1Gi
- Chrome: limit 1Gi -> 2Gi, request 512Mi -> 1Gi
- Edge: limit 1Gi -> 2Gi, request 512Mi -> 1Gi
CPU left alone on all three — observed utilization is well under the
existing limits (hub 54m / 500m, chrome 185m / 1, edge 11m / 1).

Previously orphan kubectl-applied since the Selenium Grid was first set
up. The `infra-selenium` ArgoCD app existed but only managed
`network-policy.yaml` — the deployments themselves drifted whenever
anyone `kubectl set env`'d or `kubectl scale`'d.
This commit captures the live state (with the 2026-05-25 maxSessions
bump for chrome already baked in) as canonical git source. ArgoCD's
ServerSideApply syncPolicy + selfHeal will now keep the grid in lock
step with this file.
Resources captured:
- Service selenium-hub (ClusterIP, internal traffic on 4444)
- Service selenium-hub-external (LoadBalancer, MetalLB 10.0.56.208)
- Deployment selenium-hub
- Deployment selenium-node-chrome (replicas=1, SE_NODE_MAX_SESSIONS=2)
- Deployment selenium-node-firefox (replicas=1, maxSessions=1)
- Deployment selenium-node-edge (replicas=1, maxSessions=1)
- IngressRoute selenium-hub (Traefik, selenium.iamworkin.lan)
No live behavior change — server-side dry-run confirms unchanged for
hub/firefox/ingressroute, "configured" for hub-external + 3 deploys
(default-field reordering only; SSA + field managers handle the diff).
