ZDDC

Two charts under helm/, both compile zddc-server from source via an
init container — no container image registry, no pre-built binary.
The init container clones the repo at a configured git ref, runs
`go build`, and writes the binary into a shared emptyDir; the main
container is alpine + the freshly built static binary.
helm/zddc-server-prod/ Production-shaped:
- gitRef pinned to a stable tag in
values.yaml.example (zddc-server-v0.0.7).
- imagePullPolicy IfNotPresent.
- Slower probe cadence (30s liveness, 10s
readiness).
- ZDDC_LOG_LEVEL=info.
- replicaCount: 1 (operators raise as needed
when backed by a shared filesystem).
helm/zddc-server-dev/ Dev/soak-shaped:
- gitRef defaults to "main" (rebuilt every pod
restart). build-time annotation forces
recreate on every helm upgrade.
- imagePullPolicy Always on the build image
so the latest golang:1.24-alpine is pulled.
- Faster probe cadence (10s liveness, 5s
readiness) — fail-fast in dev.
- ZDDC_LOG_LEVEL=debug. NOTE: debug logs every
request's full header map (includes auth
tokens / cookies) — this chart is for
private dev namespaces only.
- Strategy: Recreate (single replica racing
on different SHAs would be a mess).
Both charts:
- Wire the ZDDC_* env-var contract (ZDDC_ROOT, ZDDC_ADDR,
ZDDC_TLS_CERT=none, ZDDC_INSECURE_DIRECT=1, ZDDC_EMAIL_HEADER,
ZDDC_CORS_ORIGIN, ZDDC_LOG_LEVEL, ZDDC_INDEX_PATH).
- Mount a caller-supplied PVC at ZDDC_ROOT (chart does not create the
PVC; operators provision storage themselves).
- Optional Ingress (ingress.enabled: true). TLS is expected to be
terminated upstream of the pod; the pod listens on plain HTTP.
- No secrets in values.yaml.example. ACL email lists go in .zddc files
inside the data volume; image-pull and TLS secrets are referenced by
name only.
helm/README.md documents the design rationale (why build from source
instead of using a registry image), a quick-start example, and the
explicit list of what the charts do and don't do.
Note: `helm lint` cannot be run in this dev environment (helm isn't
installed). YAML syntax of Chart.yaml and values.yaml.example
verified via `python3 -c "yaml.safe_load(...)"`. Operators should
run `helm lint` and `helm template` before installing.
