wyoj-system/docker-compose.yml

# WyOJ -- one-command deployment.
#
#   docker compose up -d --build          # fresh install (creates ./uoj_data)
#   ./judger/register-judger.sh           # register the judger in judger_info
#   docker compose -f docker-compose.yml -f docker-compose.seed.yml up -d
#                                         # ... and seed the bundled production dump
#   docker compose logs -f uoj-web        # apache + install output
#   docker compose logs -f uoj-judger     # judge_client output
#   docker exec -it uoj-web bash          # shell inside the web container
#
# Layout:
#   ./db/     uoj-db image: MySQL 5.7 + the current schema (app_uoj233.sql)
#   ./web/    uoj-web image: apache + php 7.4 + the WyOJ sources (+ judger tree)
#   ./judger/ uoj-judger image: python judge_client + the C++ sandbox
#   ./uoj_data/  runtime state (mysql datadir, /var/uoj_data, app/storage)
#
# `version` is kept so this still parses with the legacy python docker-compose;
# service readiness is handled by install.sh's own wait loop, not by
# depends_on conditions, for the same reason.
#
# SECURITY: the three secrets below are placeholders that are published in this
# repository.  Change JUDGER_PASSWORD / JUDGER_SOCKET_PASSWORD / the database
# password together (and re-run ./judger/register-judger.sh) before putting this
# anywhere public.
