Postgres + Redis + API — to'g'ri yig'ilgan

qiyin

Ko'p narsa bir joyda:

db va cache uchun healthcheck (pg_isready, redis-cli ping).
api ikkalasini ham sog'lom bo'lgunicha kutsin.
db va cache yopiq; faqat api 8080 da.
Uchalasi data tarmog'ida.
db → pgdata, cache → redisdata volume.
Hammasi restart: unless-stopped.

…

  api:
    image: python:3.12-alpine
    ports:
      - "8080:8000"
