The vm-disk pvc-resize, cozystack-api, seaweedfs and vm-instance update hooks (whose alpine/k8s image this PR refreshes) ran as root with no securityContext. Add a pod-level runAsNonRoot + runAsUser 65534 + seccompProfile RuntimeDefault and a container-level allowPrivilegeEscalation: false + capabilities drop ALL, mirroring the dashboard adopt hook. kubectl needs no root, so this is behavior-neutral. Each hook is lookup-gated; pin the securityContext in a per-chart helm-unittest that mocks the gating object (DaemonSet / PVC / Service) via kubernetesProvider so the guard renders without a cluster. vm-disk and vm-instance had no Makefile test target, so add 'test: helm unittest .' to both so CI runs the new suites. Scope note: other kubectl hooks on clastix/kubectl (mariadb, keycloak, kubernetes, tenant) are untouched here — they are not part of this alpine/k8s refresh and belong to a separate hardening pass. Also fix the vm-disk resize hook's backoffLimit: it was nested under the pod spec (silently ignored, leaving the Job at the default 6 retries) instead of Job.spec. Move it to Job.spec and pin it in the test. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la>
