What is the alternative to condition form of depends_on in docker-compose Version 3? Ask Question

docker-compose 2.1 offers the nice feature to specify a condition with depends_on. The current docker-compose documentation states:

Version 3 no longer supports the condition form of depends_on.

Unfortunately the documentation does not explain, why the condition form was removed and is lacking any specific recommondation on how to implement that behaviour using V3 upwards.

From 1.27.0, 2.x and 3.x are merged with COMPOSE_SPEC schema.

version is now optional. So, you can just remove it and specify a condition as before:

services:
  web:
    build: .
    depends_on:
      redis:
        condition: service_healthy
  redis:
    image: redis
    healthcheck:
      test: ["CMD", "redis-cli", "ping"]
      interval: 1s
      timeout: 3s
      retries: 30
