- seed god_admin + nest into app_super_admin; auto-provision site groups (S_super_admin, S_hosts_*/S_apps_* aggregates, S_everyone) on site create + self-heal on Directory load - map service resources to the app kind (site_local_app_<slug>_*); nest per-resource groups into site aggregates (physical inheritance lattice) - enforce the group naming convention server-side on POST /groups; surface god_admin + site groups on the site resource modal - fix in-app /docs/<slug> 500s (Dockerfile never copied docs/); serve doc images at /docs/images - fix Directory status dots (neutral grey when agent endpoint unreachable); align Profile/API cards full-width - group resolver: keep the site slug verbatim (site_local not re-slugified) - bump to 1.26.0

# 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 from source ─────────────────────────────────────────────────────
|
|
# We build slapd from OpenLDAP master rather than installing Alpine's packages,
|
|
# for exactly one feature: the `nestgroup` overlay (ITS#10161, Howard Chu,
|
|
# 2024-03-21), which evaluates nested groups server-side. Nothing in any 2.6.x
|
|
# release can do this -- verified: 2.6.13 ships 26 overlay modules and
|
|
# nestgroup is not among them -- and the alternative is resolving nesting
|
|
# separately in every consumer (this app, SSSD on each host, jump-host, proxy),
|
|
# where any consumer that forgets silently under-grants access.
|
|
#
|
|
# Consequence to know about: master ships LMDB 1.0.0, whose on-disk format the
|
|
# 0.9.x used by 2.6.x cannot read, and vice versa
|
|
# ("MDB_INVALID: File is not an LMDB file"). Moving an existing directory onto
|
|
# this image is a slapcat/slapadd migration, not a restart. See DEPLOYMENT.md.
