From 6797e11eb2c5905fc84273387c40ff2ef330e6fa Mon Sep 17 00:00:00 2001 From: Aleksei Sviridkin Date: Sun, 28 Jun 2026 03:09:02 +0300 Subject: [PATCH] fix(kubernetes): make node group resources optional and prefer them over instanceType MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A node group is sized either by instanceType or by explicit resources, but the generated values schema required resources on every node group. A node group with instanceType and no resources — or an empty resources dropped during typed-CR to HelmRelease translation — failed schema validation with "missing property 'resources'" even though sizing was fully specified. Mark resources optional in the node group definition and regenerate the schema, API types, README, and ApplicationDefinition. The chart template emits domain.cpu/memory only when resources is present, so a node group sized purely by instanceType now passes validation and installs. When a node group sets both instanceType and explicit resources, explicit resources take precedence: the instancetype is omitted from the rendered VM and the per-group instancetype lookup is skipped, so KubeVirt accepts the explicit domain.cpu/memory with no instancetype to conflict with. instanceType stays required and defaulted (no schema change), so the console's required instanceType dropdown keeps working — sending the default instanceType plus explicit resources simply sizes the VM by resources. This replaces an earlier render-time hard failure on the both-set case, which was unreachable to clear from the dashboard (the required dropdown cannot be emptied). Explicit resources are all-or-nothing alongside an instanceType: a partial spec (only cpu, or only memory) on a group that carries a non-empty instanceType would emit one domain override next to the instancetype — which KubeVirt rejects — so it now fails at render time with a clear error. Partial resources on a group without an instanceType (used to tune kubelet reservations) are unaffected.
