+# Ako pustit Docker na macOS
+
+## Co pustam
+
+- `docker-compose -f deployment/local-mac/compose.yaml up --build --force-recreate`
+  - da sa prihodit aj `--detach` ked chceme pustit v backgrounde (bez neho vidime server logy priamo v terminali)
+
+Treba mat samozrejme Docker a docker-compose atd.
+
+## Urobene zmeny oproti compose-test
+
+Ked som chcel pustit Docker na macu, musel som urobil nasledujuce zmeny (poradilo ChatGPT):
+
+### `compose.yml`
+
+- zmenil som aj meno suboru (lebo nebuildime "test" environment a.k.a test.strom.sk)
+- vymena `network_mode: host` za `ports: - '3000:3000'` - network_mode vraj na macu nefunguje
+- pridanie `- NEXT_PUBLIC_BE_HOSTNAME=host.docker.internal` - aby sa to vedelo pripojit na lokalny BE - Docker pouziva takyto hostname pre host machine localhost
+- zmenil som porty na 3000/8000 ako standardne pouzivame pre development
+- `dockerfile` a `context` cesty podla file struktury novych suborov
+
+### `Dockerfile`
+
+- host v `ENTRYPOINT`e na `"0.0.0.0"`
+  - od ChatGPT: You're trying to start the application with `yarn start -H localhost`. This command might not be correctly binding to all network interfaces. Usually, you'd use `-H 0.0.0.0` to ensure the app listens on all interfaces, including those available within a Docker container. (a naozaj to pomohlo, inak mi stranku browser nenacital)
+- pridany `ARG NEXT_PUBLIC_BE_HOSTNAME` pre nacitanie env varu z compose
+
+### BE `settings.py`
+
+- `ALLOWED_HOSTS = ['host.docker.internal']` - BE krical, ze treba :shrug:
