# Dockerfile.tenant — combined platform (Go) + canvas (Next.js) image.
#
# Serves both the API (Go on :8080) and the UI (Node.js on :3000) in a
# single container. Go reverse-proxies unknown routes to canvas.
#
# Templates + plugins are NOT cloned at build time. They are pre-cloned
# in the trusted CI context (or operator host) by
# `scripts/clone-manifest.sh` into `.tenant-bundle-deps/` and COPYed in.
# The reason: post-2026-05-06, every workspace-template-* repo on Gitea
# (codex, crewai, deepagents, gemini-cli, langgraph) plus all 7
# org-template-* repos are private, so the Docker build can't `git clone`
# from inside the build context — there's no auth path that doesn't leak
# the Gitea token into an image layer. Pre-cloning keeps the token in
# the CI environment only; the resulting image carries the cloned trees
# with `.git` already stripped (see clone-manifest.sh).
#
# Build context: repo root, with `.tenant-bundle-deps/` populated by:
#
#     MOLECULE_GITEA_TOKEN=<persona-PAT> scripts/clone-manifest.sh \
#       manifest.json \
#       .tenant-bundle-deps/workspace-configs-templates \
#       .tenant-bundle-deps/org-templates \
#       .tenant-bundle-deps/plugins
#
# In CI this happens in publish-workspace-server-image.yml's "Pre-clone
# manifest deps" step (uses AUTO_SYNC_TOKEN = devops-engineer persona).
# For a manual operator-host build, source the same token from
# /etc/molecule-bootstrap/agent-secrets.env first.

# fails closed — which is the correct fail-direction (#2395 root fix).
