rootnode-academy/platform/docker-compose.dev.yml

# Phase 2B full-stack local dev/test — Postgres + egress-proxy + Provisioner + the lightweight
# Platform API + the Gateway, all on one machine (the documented Phase 1/2A/2B dev exception;
# production is the two-VM Proxmox split, see docs/LAB_ARCHITECTURE.md §1).
#
# `api` (platform/api) replaces Phase 2A's "identity" service — that was a full, --privileged
# Lab image booting an unused k3s cluster just to serve roster/curriculum/progress APIs. This
# is a plain Node process: no k3s, no --privileged, no terminal runtime. It owns
# students/cohorts/enrollments/curriculum/progress/scenario_attempts in Postgres and is the
# only service that talks to the Provisioner (student launch/reset AND instructor/admin
# actions) — see docs/PHASE2B_ADMIN_AND_PLATFORM_DATA.md.
#
# gateway, provisioner, and api's egress-adjacent needs aside, `api` does NOT need
# network_mode: host — it never touches Docker networking or firewall rules itself, it only
# calls the Provisioner's HTTP API and Postgres. gateway and provisioner keep network_mode:
# host because they need to reach ephemeral per-student Lab containers by internal IP /
# manage firewall rules on the host network namespace.
