Collapse the chart to a single Deployment shape that mirrors
cozystack-api: 2 replicas, soft (preferred) nodeAffinity to
node-role.kubernetes.io/control-plane via Exists, permissive
tolerations, soft podAntiAffinity on hostname, an unconditional
PodDisruptionBudget with maxUnavailable: 1, and a Service with
spec.trafficDistribution: PreferClose. The same shape works on
Talos / kubeadm / k3s and on managed Kubernetes / Cozy-in-Cozy
tenant clusters without per-distro overrides — fixing #2417 by
making the soft control-plane affinity gracefully fall back to
worker scheduling when no control-plane nodes are visible.
Drop the DaemonSet path entirely. The previous PR's deployment.enabled
toggle, the workload-kind switch in templates/workload.yaml, the
fail-guard for localK8sAPIEndpoint+nodeAffinity=[], the conditional
PDB, and the values-shape knobs for nodeAffinity and tolerations all
go away as a consequence. Override the standard Deployment fields
through the usual component-values mechanism if a non-default topology
is ever needed.
Mark localK8sAPIEndpoint.enabled deprecated and flip the default to
false. The flag injects KUBERNETES_SERVICE_HOST=status.hostIP, which
is only valid when the pod is actually scheduled on an apiserver-
bearing node. With the new soft control-plane affinity, the pod can
land off-control-plane and crash-loop. The latency motivation for the
flag is real but pending separate webhook performance work; once
addressed, the flag can be removed.
Revert all changes to packages/core/platform/images/migrations/migrations/20.
The earlier ds/...-or-deploy/... fallback was over-engineered: per
run-migrations.sh, migration 20 fires only when CURRENT < 20 (i.e.
direct upgrades from pre-0.37 to 1.3+), and that path is unsupported
anyway. The original ds/... rollout-status line is dead code on every
supported install and upgrade path.
Add helm-unittest coverage for: the default Deployment shape (replicas,
soft nodeAffinity, soft podAntiAffinity, tolerations); no env vars at
the default localK8sAPIEndpoint.enabled=false; PDB rendered
unconditionally with maxUnavailable: 1, including at replicas=1 (the
no-op case); replicas value drives spec.replicas; and that
localK8sAPIEndpoint.enabled=true does inject the env vars. The Service
test continues to assert trafficDistribution: PreferClose with no
internalTrafficPolicy.
Add a slim README documenting the topology, parameters, and the
deprecation note for localK8sAPIEndpoint.
