Three changes, across both workloads (Synapse StatefulSet and delegation
nginx Deployment).
1. values.schema.json (#68): additionalProperties: false on every
chart-owned object level, including the whole matrix.delegation block
with its own contexts, probes and resources.
2. Ingress gate (#93): the Ingress template is wrapped in
{{- if .Values.ingress.enabled }} and the key is added to values.yaml
with default true, so behaviour is unchanged.
The domain checkpoint found a second reader: the delegation nginx
serves ingress.domain in its /.well-known/matrix/{server,client}
endpoints, and read it without a guard. Gating alone would therefore
have published '{"m.server": ":443"}' and base_url "https://" - a
federation-breaking answer that renders and starts cleanly. Both reads
are now required(), so that case fails loudly. Only clusterIssuer
actually becomes unnecessary when the Ingress is off.
3. Null-safety for hardening, probes and resources (#99) for both
workloads. The rebuilt probes keep each workload's own endpoint:
Synapse /health, delegation /.well-known/matrix/server - the endpoint
that workload exists to serve - including its shorter 3s timeout. The
delegation pod context keeps having no fsGroup, because it mounts no
volume that needs one.
The nginx checksum/config annotation from #82 is untouched.
storage stays deliberately not null-safe: an erased block yields an
invalid PVC, which is the loud class #99 excludes.
Rendering is byte-identical to 6.0.0, both with the CI values (which
enable delegation) and with the production bundle values.
- Values-driven securityContext for the Synapse pod/container with hardened
defaults: runAsNonRoot as uid/gid 1000 (matching the image's previous gosu
drop target), readOnlyRootFilesystem, allowPrivilegeEscalation false, all
capabilities dropped; /tmp mounted as emptyDir. The now-ineffective UID/GID
env vars are removed (the securityContext controls the user).
- Naming scheme: delegation Deployment renamed to ...-delegation-nginx-deployment,
ConfigMap to ...-delegation-nginx-configmap (references and service selector
updated).
- matrix.configSecretRef moved to secrets.configSecretRef (repo standard).
- Probes for Synapse and the delegation nginx are values-configurable;
defaults are the previous hardcoded settings.
- Flexible ingress standard: ingress.className (default nginx) and
ingress.annotations merged with the cert-manager annotation.
- Additive matrix.env block rendered through tpl (value/secretKeyRef/
configMapKeyRef forms).
- CI fixtures: secret ref moved, seed job image synced to appVersion.
- Chart 4.2.1+upv1.159.0 -> 5.0.0+upv1.159.0 (major; app version unchanged).
