Description

Panic on improper compose override.

Steps To Reproduce

Create file docker-compose.yml:

include:
  - path:
    - ./base.yml
    - ./base-compose-override.yml

Create file base.yml:

networks:
  foo-network:
    ipam:
      config:
        - subnet: 172.16.0.0/24
          gateway: 172.16.0.254
          aux_addresses:
            foo1: 172.16.0.1
            foo2: 172.16.0.2
            foo3: 172.16.0.3
            foo4: 172.16.0.4

Create file base-compose-override.yml:

networks:
  foo-network:
    ipam:
      config:
        aux_addresses:
          foo1: !reset null
          foo2: !reset null
          foo3: !reset null

Run docker compose config and observe panic:

$ docker compose config
panic: interface conversion: interface {} is map[string]interface {}, not []interface {}

Your base-compose-override.yml file is invalid. ipam.config must be an array. This also prevents use of !reset here to remove elements in the existing list. You'll have to fully override the config definition
