Great config file.
Thanks buddy

@phuysmans, thanks man 🐱‍👤

test: redis-cli ping if you want to be a bit neater :)

condition parameter is no longer supported by docker v3.0 and above

@wajdijurry
Thanks for the information

Thanks a lot, wish found it yesterday

@wajdijurry Not true, condition is supported by the compose specification:

Yo, do you see the version 👆 (2.1)
Think before you write plz

Think before you write plz

Please don't be mean. It doesn't do anyone any good and only spreads a bad mood.
We're all in the same boat.

@danmutblix Actually this does work with the docker-compose 2.1 format:

$ docker-compose config
services:
  nginx:
    depends_on:
      postgres:
        condition: service_healthy
    image: nginx:1.20
  postgres:
    environment:
      POSTGRES_PASSWORD: test
    healthcheck:
      test: pg_isready
    image: postgres:13
version: '2.1'

$ docker-compose up -d
Building with native build. Learn about native build in Compose here: https://docs.docker.com/go/compose-native-build/
Creating network "ok_default" with the default driver
Creating ok_postgres_1 ... done
Creating ok_nginx_1    ... done
$ 

condition was removed for the 3.x compose format but reintroduced with the compose specification. So, it worked in 2.1+ and it works now.

Yes, I'm sorry 😔

We're literally working with docker health checks, it's too easy to get frustrated with this stuff
