Add securityContext hardening (runAsNonRoot, readOnlyRootFilesystem, capabilities drop ALL, allowPrivilegeEscalation false) to the 10 workloads that lacked it: apache-tika, cyberchef, gotenberg, homeassistant, matrix-delegation-nginx, paperless-server, paperless-consume cronjob (plus automountServiceAccountToken false), patchmon-frontend, urlaubsverwaltung and zipline. All contexts are configurable via securityContext.pod / securityContext.container in values.yaml; writable paths are provided as emptyDirs. Image-forced deviations (Home Assistant root start for s6-overlay + NET_RAW for discovery, paperless root init container for /run ownership) are documented in the charts' values.yaml. Major version bump for every changed published chart.

# Documented deviation from the repo-wide hardening standard: the official
|
|
# Home Assistant container must start as root — it boots via the s6-overlay
|
|
# init system, which performs its setup as uid 0 (the image supports no
|
|
# non-root user), so runAsNonRoot/runAsUser are deliberately not set.
|
|
# Everything else is hardened: no privilege escalation, all capabilities
|
|
# dropped and a read-only root filesystem with writable emptyDirs for
|
|
# /tmp and /run (s6-overlay state). NET_RAW is added back because Home
|
|
# Assistant's device discovery (DHCP watcher, ping/arp integrations) uses
|
|
# raw sockets and logs "Operation not permitted" without it.
