This commit completes Phase 0 of Approach C: the CCP template/env/static
files now produce output structurally byte-identical to canonical
docker-compose.prod.yml + .env.example. Verified by rendering against
marcelle, linda, and pia and diffing against their actual files — all
three show only the 30-line CCP-tenant header comment differing,
zero service/env-var structural differences.
Changes:
- templates/docker-compose.yml.hbs: reverted {{imageTag}} substitutions
back to ${IMAGE_TAG:-latest} so the compose template is now byte-
equivalent to docker-compose.prod.yml (modulo header). CCP controls
per-instance image tag selection via the rendered .env's IMAGE_TAG,
which compose-up picks up at runtime. This single-source-of-truth
via env-substitution matches install.sh tenants exactly.
- templates/env.hbs: rewritten as a near-mirror of .env.example. Adds
27 missing keys (IMAGE_TAG, GITEA_REGISTRY, COMPOSE_PROFILES,
ENABLE_CCP_AGENT, GITEA_ADMIN_*, ENABLE_HLS_TRANSCODE, TZ, etc.)
plus 15 CCP-specific extras (embed ports, dev-mode helpers, etc.).
All 145 compose-template env-var references are now covered.
- templates/nginx/nginx.conf: synced from canonical. Includes recent
security additions: redacted access-log format for token/secret
query params, rate-limit zones (api_global, api_auth, upload),
conditional HSTS via X-Forwarded-Proto map.
- api/scripts/render-for-instance.ts (new): one-off CLI that loads
an Instance row, decrypts secrets if present (or uses empty object
for isRegistered=true tenants), and calls renderAllTemplates() to
a scratch dir. Used in Phase 0.4 to verify the template-vs-prod
contract per tenant.
Usage:
docker compose exec ccp-api npx tsx scripts/render-for-instance.ts \
--slug changemakerlite
Phase 0 acceptance gate met:
- marcelle (release v2.10.2 install): 30-line diff, header-only
- linda (release v2.9.14 install): 30-line diff, header-only
- pia (release v2.9.10 install): 30-line diff, header-only
- env.hbs key coverage: 0 missing vs marcelle's .env
Next phases unblocked:
- Phase 1: add Instance.imageTag column (Prisma migration)
- Phase 2: pre-flight diff endpoint
- Phase 3: startReleaseUpgrade runner
- Phase 4: routes + schemas
- Phase 5: CCP UI "Upgrade to Release" button
- Phase 6: E2E test on marcelle (v2.10.2 -> v2.10.3)
