docker-compose Postgres health-check

docker-compose.yml

version: "3"
services:
  postgress:
  ....
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 10s
      timeout: 5s
      retries: 5
  app:
    ...
    depends_on:
      postgres:
        condition: service_healthy

Thanks!

Gives me this error:

ERROR: The Compose file './docker-compose.yml' is invalid because:
services.app.depends_on contains an invalid type, it should be an array

Seems like this approach is no longer valid. Since docker-compose changed it's behavior with depends_on in latest updates.

Version 3 no longer supports the `condition` form of `depends_on`.

more about this you can find here: -> https://docs.docker.com/compose/compose-file/#depends_on

There is a new approach with wait-for-it.sh script.

More about it here: https://docs.docker.com/compose/startup-order/

Thank you zhunik very much!!! :)
For other people who want to know more about the command, please visit postgres documentation

Thanks! Worth noting is that pg_isready with just user specified will check against the db called the same as the username.

thanks!
