# Session 0023: Toolkit Bootstrap Starting Point

**Date:** 2026-02-23
**Status:** Completed
**Origin:** MDF Webseiten session 0045

---

## Work Done

- [x] Created `project.yaml` descriptors for all 5 projects (mdf, seriousletter, ringsaday, kioskpilot, ops-dashboard)
- [x] Updated `ops-dashboard` docker-compose.yaml: network `coolify` → `proxy`
- [x] Added Alpine pre-pull with retry (4 attempts, 15s delays) to `rebuild.py` — note: this was a pre-redesign patch, superseded by Phase 5 rewrite in session 0046
- [x] Added image verification after build to `rebuild.py`
- [x] Identified Phase 3+4 toolkit work as next immediate task (was interrupted this session)

## Context / Background

This session was primarily about removing Coolify and migrating all projects to standalone Docker Compose. The OPS-relevant outcome is:

- All 5 `project.yaml` descriptors now exist and are the source of truth for the toolkit
- The `proxy` Docker network replaces the old `coolify` network — all Traefik-exposed containers connect to it
- The toolkit build (Phase 3+4) was planned but interrupted mid-session — completed in session 0046
- The plan was documented at: `Notes/swarm/plan.md` (since cleaned up)

## Key Decisions / Learnings

- `container_prefix` in `project.yaml` uses `{env}` placeholder (e.g. `"{env}-mdf"`) — the toolkit must expand this at runtime
- SeriousLetter uses `"{env}-seriousletter"` as prefix (not `sl`)
- ops-dashboard gets its own `project.yaml` like all other projects

## Files Changed

- `/opt/data/mdf/project.yaml` — created
- `/opt/data/seriousletter/project.yaml` — created
- `/opt/data/ringsaday/project.yaml` — created
- `/opt/data/kioskpilot/project.yaml` — created
- `/opt/data/ops-dashboard/project.yaml` — created
- `/opt/data/ops-dashboard/docker-compose.yml` — network coolify→proxy
- `app/routers/rebuild.py` — Alpine retry + image verify (pre-redesign, superseded)
