this is both more and less secure then before.
we intenally made show the placemetn cofnig were owned by placment adn restricted to 0600 by kolla
i guess group access is ok
so 0440 is now makign the etc mounts readony but expanding it to the group
we dintentally didnt do this before bacue the projected files will be owned as root whcih sis incorrect
now we can use
fsGroup: 1001 in the securityContext
to change the group fo the projected fiels to bey placement gid
and 0440 will then allow placement to read it
but this sitll change the cofnig to be owned as root which while it would work is not a good security practice in general.
as far as im aware there is no way to set the user of the fiels natively in k8s so this is a trade off we can make but the other reason we didnt do this in the past was we want the same behvior on the edpm nodes
so if we are entrusting this to k8s to do via projecting the volume with specific permission we will need to restructure the ansibel to ensure the same is done on the edpm node via bind mounts and chowing the files on the host.
doable but we should not keep kolla in one place and remvoe it in the other. that does not impact placmenet but its a wider condieration

yes correct, using the fsgroup in the context is what we do. I just see that I pass the UID, which works as long the UID/GID are the same, but I should update the RestrictivePodSecurityContext helper func to also take the GID.
we discussed the consistency topic re ctlplane/edpm in yesterdays tech call and the consent was that when we do the move away from kolla on the ctlplane side to be able to not have to run the deployments with elevated permissions, which kolla need to run sudo, we should also do it on the edpm side, to be consistent. jslagle took the item to create the tracker for it and follow up.

test/kuttl/test-suites/placement/common/assert_sample_deployment.yaml#L158-L183
by removing the API, HTTPD, and obsolete scripts mounts. In

remove the API, HTTPD, CA, and TLS mount expectations, leaving only mounts
provided by the generated log container.

Eliminate kolla_start/kolla_set_configs and the config.json staging pattern for the placement service. Configs are now mounted directly to final paths via SubPath volume mounts, removing the need for root privilege escalation at container startup. Second operator in the remove-kolla effort, following keystone-operator. Key changes: - Delete placement-api-config.json / placement-dbsync-config.json - Mount configs via SubPath to /etc/placement/, /etc/httpd/, /etc/my.cnf - Add emptyDir volumes for writable paths (/run/httpd, /tmp, /var/log/httpd) using lib-common volume.WritableDirVolume() and volume.WritableDirVolumeMount() helpers with named constants (RunHttpdVolumeName, TmpVolumeName, VarLogHttpdVolumeName); the pre-existing /var/log/placement "logs" emptyDir (used by the oslo.log tailing sidecar) is unrelated to kolla and unchanged - Standardize config-data Secret DefaultMode to 0440 (was 0640), matching the lib-common configSecretMode convention - Replace kolla_start with /usr/sbin/httpd -DFOREGROUND (api container) and placement-manage db sync (db-sync job) - Remove KOLLA_CONFIG_STRATEGY and KOLLA_BOOTSTRAP env vars - Use pod.RestrictiveSecurityContext and RestrictivePodSecurityContext from lib-common on all 3 containers (-log, -api, -db-sync), setting ReadOnlyRootFilesystem, dropping ALL capabilities, and enabling seccomp RuntimeDefault - Set AutomountServiceAccountToken=false on both workloads - Import PlacementUID from lib-common modules/serviceuser - Override TLS CertMount/KeyMount to /etc/pki/tls/ for Apache - Migrate placement's SCC from anyuid to nonroot-v2 -- additive change in this multi-controller operator: nova and cyborg keep their own anyuid markers/rbacRules untouched, config/rbac/role.yaml gains a new nonroot-v2 rule alongside the existing anyuid one - httpd.conf: User/Group placement, PidFile /run/httpd/httpd.pid, re-enable Include conf.d/*.conf (previously disabled due to a syntax error that no longer applies once kolla's generated ssl.conf is what's actually loaded), vhost ErrorLog to stderr - policy.yaml mounted conditionally on DefaultConfigOverwrite, matching prior (narrow) kolla behavior -- no scope expansion - Adopt lib-common volume helpers (volume.WritableDirVolume, volume.WritableDirVolumeMount) for all emptyDir volumes and mounts, using constants for run-httpd, var-log-httpd, and tmp names/paths - Update functional and kuttl tests Jira: OSPRH-33504 Jira: OSPRH-33503 Depends-On: openstack-k8s-operators/lib-common#728 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Martin Schuppert <mschuppert@redhat.com>
