[BUG] docker compose config does not provide validation logic for complete project when individual compose file has profiles mentioned it

[shantanoo-desai]

Description

validation of a compose file(s) provides invalid output when performing docker compose config on the complete project as well as on individual files. This bug makes it not possible whether the docker compose files / project is actually valid or not.

Steps To Reproduce

Following is the test structure:

bug-dc-profiles
.
├── compose.yml
├── docker-compose.test1.yml
└── docker-compose.test.yml

Contents with profiles specified

profile names are only for testing purpose and bear no real utility in this example

docker-compose.test.yml

services:
  test_cntr:
    image: alpine:latest
    command: "echo test"
    profiles: 
      - test-prof

docker-compose.test1.yml

services:
  test-cntr-2:
    image: ubuntu:latest
    command: "echo test1"
    profiles:
      - test-debug-prof

compose.yml (entrypoint file)

include:
  - path: ./docker-compose.test.yml
  - path: ./docker-compose.test1.yml

Testing with profiles

> docker compose config
name: bug-dc-profiles
services: {}

testing it with individual files:

> docker compose -f docker-compose.test.yml config
name: bug-dc-profiles
services: {}

> docker compose -f docker-compose.test1.yml config
name: bug-dc-profiles
services: {}

Content without profiles

removing profiles from either one of the file provides a configuration validation but with only the contents of the file where those profiles were removed.

docker-compose.test1.yml

services:
  test-cntr-2:
    image: ubuntu:latest
    command: "echo test1"

docker-compose.test.yml remains the same as before

Testing without profiles

> docker compose config
name: bug-dc-profiles
services:
  test-cntr-2:
    command:
      - echo
      - test1
    image: ubuntu:latest
    networks:
      default: null
networks:
  default:
    name: bug-dc-profiles_default

as seen here only the test-cntr-2 is validated.

removing profiles from all the files gives the accurate output:

> docker compose config # removed all profiles from files
name: bug-dc-profiles
services:
  test-cntr-2:
    command:
      - echo
      - test1
    image: ubuntu:latest
    networks:
      default: null
  test_cntr:
    command:
      - echo
      - test
    image: alpine:latest
    networks:
      default: null
networks:
  default:
    name: bug-dc-profiles_default

Anything else?

• docker compose config --profiles lists out the profiles, but docker compose config --services does not provide anything.

• Only when the profiles are removed does docker compose config --services lists the values of the services.

• only was to resolve this solution is docker compose --profile test-debug-prof config provides the configuration of the specific file.

[ndeloof]

config command goal is not to provide validation of a whole compose file, but to compute and show the actual model that will be used by other compose commands. Disabled profiles then are excluded, as one could expect.
You can for all profiles to be enabled by running docker compose --profile="*" config
