ops/backup.sh snapshots LDAP (slapcat), Redis (BGSAVE, dynamic RDB path lookup), and ./config for standalone deployments, with retention. A background service polls GitHub releases every 24h and surfaces an admin-only banner in the UI when a newer version is published.

# Theta42 SSO Manager with OpenLDAP - All-in-One Dockerfile
|
|
# App + OpenLDAP in a single container, for development/testing or a
|
|
# self-contained single-node deployment. For production, run a dedicated
|
|
# LDAP server and configure the app via app_* env vars / mounted secrets.js.
|
|
|
|
# ── Git commit hash (build-time only) ────────────────────────────────────────
|
|
# The final image intentionally has no git binary and no .git directory (kept
|
|
# lean, per .dockerignore), so `git rev-parse` always fails at runtime and
|
|
# build_info.js silently fell back to "unknown". Resolve it here instead,
|
|
# where .git IS available (build context), and bake just the short hash into
|
|
# a file — this stage itself is discarded, only /commit.txt survives via the
|
|
# COPY --from below. Reuses the main base image (already pulled for the real
|
|
# build below) rather than a separate one, so this adds no extra image pull.
|
|
#
|
|
# GIT_COMMIT lets a caller override the resolved hash instead of computing it
|
|
# from .git in this build context. Needed when this repo is built as a git
|
|
# submodule (e.g. from theta-env): a submodule's .git is a pointer FILE, not
|
|
# a directory — the real object database lives in the superproject's
|
|
# .git/modules/, outside this repo's own directory and therefore outside
|
|
# Docker's build context entirely, so `git rev-parse` can never resolve it
|
|
# from in here no matter what. theta-env's setup.sh passes --build-arg
|
|
# GIT_COMMIT=$(git -C sso-manager-node rev-parse --short HEAD), computed on
|
|
# the host where the submodule resolves correctly.

# openldap-back-mdb : the mdb backend (slapd.conf uses `database mdb`)

|

# openldap-overlay-refint : referential integrity on group members
|
|
# openldap-passwd-sha2 : pw-sha2 module ({SSHA512} user password hashing)
|
|
# Note: Alpine does NOT ship a ppolicy.schema file — on OpenLDAP 2.6 the ppolicy
|
|
# schema is built into ppolicy.so and registered when the module loads, so
|
|
# docker-entrypoint.sh loads it via `moduleload ppolicy` (no schema include).
