Eliminate kolla_start and the config.json staging pattern across all Octavia workloads. The crudini config-merge init container (Pattern C: merges parent + child config into a config-data-merged emptyDir) is kept exactly as-is -- only kolla's staging-to-final copy step is replaced with SubPath mounts of the same emptyDir at final paths. Key changes: - octavia-api: replace kolla_start with /usr/sbin/httpd -DFOREGROUND; mount httpd.conf/ssl.conf via SubPath to /etc/httpd/conf[.d]/; add run-httpd emptyDir at /etc/httpd/run (not the canonical /run/httpd because octavia's httpd.conf uses PidFile relative to ServerRoot) - octavia-driver-agent: add explicit Command (/usr/bin/octavia-driver-agent --config-file ... --config-dir ...) - octavia-worker/housekeeping/healthmanager: exec octavia_controller_start.sh <role> directly - octavia-rsyslog: exec /usr/sbin/rsyslogd -n directly; add NET_BIND_SERVICE capability for privileged port 514 binding; delete the now-redundant octavia_rsyslog_start.sh wrapper - db-sync: exec bootstrap.sh directly - All root init containers (amphora, rsyslog, image-upload): add RunAsNonRoot: false to override pod-level RunAsNonRoot: true from RestrictivePodSecurityContext; add Drop: ALL + explicit Add for needed capabilities (amphora: NET_ADMIN/NET_RAW/SYS_ADMIN/SYS_NICE, rsyslog: NET_ADMIN/NET_RAW/SYS_ADMIN/SYS_NICE) - Add GetConfigOverwriteVolumeMounts() for conditional policy.yaml - Remove all KOLLA_CONFIG_STRATEGY/KOLLA_BOOTSTRAP env vars and 7 config.json templates - Use pod.RestrictiveSecurityContext/RestrictivePodSecurityContext from lib-common (serviceuser.OctaviaUID) on all main containers - Fix TLS cert staging-path bug on octavia-api and driver-agent - httpd.conf: User/Group apache -> octavia - RBAC: add nonroot-v2 additively (anyuid;privileged;nonroot-v2) - DefaultMode 0440 across all volumes - Adopt lib-common volume.WritableDirVolume helpers - AutomountServiceAccountToken: false on all workloads - Update functional and kuttl tests The amphora-controller/rsyslog init containers keep RunAsUser:0 and elevated capabilities (NET_ADMIN/NET_RAW genuinely used for network setup; SYS_ADMIN/SYS_NICE left in place pending verification). octavia-image-upload's init container keeps RunAsUser:0 (external image entrypoint, not verifiable without real cluster).
