docker compose v2 cannot override service healthcheck test

[martinsvoboda]

Description

I would like to override service healthcheck test. Works fine on v1, but docker compose v2 do not override test value. It to append new value to previous one.

Steps to reproduce the issue:

$ cat docker-compose.yml
version: '3.8'
services:
  nginx:
    image: nginx:1.21.4
    healthcheck:
      test: curl --fail -I http://localhost/ || exit 1

$ cat docker-compose.dev.yml
version: '3.8'
services:
  nginx:
    image: nginx:1.21.4
    healthcheck:
      test: exit 0

Describe the results you received:

V2 rather append healthcheck-test than override.

$ docker compose -f docker-compose.yml  -f docker-compose.dev.yml config
services:
  nginx:
    healthcheck:
      test:
      - CMD-SHELL
      - curl --fail -I http://localhost/ || exit 1
      - CMD-SHELL
      - exit 0
    image: nginx:1.21.4
    networks:
      default: null
networks:
  default:
    name: compose-test_default

Describe the results you expected:

V1 override the healthcheck-test

$ docker-compose -f docker-compose.yml  -f docker-compose.dev.yml config
services:
  nginx:
    healthcheck:
      test: exit 0
    image: nginx:1.21.4
version: '3.8'

I got the same problem with docker version Docker version 20.10.17, build 100c701
Healthcheck's can't be overwritten with the override file.

[tboddyspargo]

Thanks for reporting this! I'm just noting my shared experience of issues merging healthcheck config with v2. In my case, I only wanted to override the interval key, but leave the actual test key that was defined in the primary compose config. In this situation, it's possible to get an error claiming that container for service "xxxxxxxxxxxx" has no healthcheck configured on a linux machine using compose version 2.14.2.

I tried to reproduce the reproduction scenario with latest release and get the expected behavior

$ docker compose -f compose.yml -f compose-dev.yml config
services:
  nginx:
    healthcheck:
      test:
      - CMD-SHELL
      - exit 0
    image: nginx:1.21.4
    networks:
      default: null
networks:
  default:
    name: truc_default

I guess this is a duplicate for #9756, fixed by compose-spec/compose-go#321

@tboddyspargo if you can provide a concrete example to reproduce the side issue you describe, please open a new issue so we can investigate
