Production image for the frontend dist. Stage 1 (build): node:22-alpine, `npm ci --ignore-scripts` from the committed lockfile, `npm run build`. Output lands in /app/dist. Stage 2 (runtime): docker.io/nginxinc/nginx-unprivileged:alpine. - Upstream-maintained variant that runs as the nginx user (uid 101) out of the box. /var/cache/nginx and /var/run/nginx are pre-owned, no chown gymnastics needed in our layer. Vanilla nginx:alpine fails at startup as non-root because client_temp mkdir is denied. - Listens on 8080 (non-privileged port, matches the unprivileged variant convention). - nginx.conf serves /usr/share/nginx/html with SPA `try_files` fallback for client-side routing, long-cache headers on /assets/ (Vite hashed bundles), a plaintext /healthz endpoint for Caddy / Prometheus blackbox, and server_tokens off. .dockerignore excludes node_modules, dist, .vite, coverage, playwright-report, .env*, .git, editor dirs. Keeps .env.example. Smoke local validated with `podman build -t mimic-frontend:smoke .` and `podman run -p 127.0.0.1:18080:8080`: /healthz -> 200 "ok" / -> 200 index.html (508 B) /spa/x -> 200 (SPA fallback) /assets -> Cache-Control: max-age=31536000, public, immutable
Mimic
Internal BAS (Breach & Attack Simulation) platform for the Red Team. Replays TTPs from engagement journals or an internal ATT&CK library against client infrastructure through VPN/relay, in white-glove coordination with the SOC.
Output: a coverage report mapped to MITRE ATT&CK — measurable, reproducible, archived.
Status
ready-with-prereqs — spec frozen on 2026-05-19, 23 review patches integrated.
Code start blocked on:
- PR1 — Mythic API documentation + pinned version (lead RT)
- PR2 — Internal C2 interface spec + journal export example (internal C2 team)
- PR3 — RT graphic charter for the PDF report (lead RT)
While PR1/PR2/PR3 are open, sprint 0 focuses on the unblocked skeleton.
Spec
The authoritative spec lives in the RT-SecondBrain vault:
Projects/Mimic — Spec.md. Do not duplicate it here.
In-repo documentation:
CHANGELOG.md— chronological log of features, decisions, rollbacks.tasks/spec-decisions.md— implementation arbitrations on top of the spec.tasks/todo.md— current sprint backlog.
Stack (frozen)
- Backend Python 3.12 / Flask / Flask-SocketIO / SQLAlchemy 2 / Pydantic 2 / Alembic / WeasyPrint / pytest + testcontainers / ruff / mypy strict
- Frontend TypeScript / React 18+ / Vite / Tailwind 4 / TanStack Query 5 / Recharts / Playwright
- Storage Postgres (prod) / SQLite (pure-logic unit tests) / testcontainers Postgres (audit log, RBAC, write-only role — incl. unit tests of Postgres-specific behavior, per H38)
- Deploy Docker images + Ansible deployment playbook (per D-010). Reverse proxy (Caddy + TLS + IP allowlist) handled by existing RT infrastructure, out of Mimic scope (D-007).
