Override docker not working

I change ports in file 'docker-compose.override.yml' and run docker (docker-compose up). Docker isn't seeing my changes (ports) in override.

Content override:

version: '2'

services:
    nginx:
        ports:
            - 87:80

Why docker isn't changing the port?

Had the same issue and found the solution, this comes from the way docker merges files and nodes, in your case it probably appended the ports to an already existing ports node coming from your base docker-compose.yml file.

What you can do in this case is to override the node value :

services:
  nginx:
    ports: !override
      - 87:80

NB: not sure if it works on all docker compose versions, but you never know if it might help someone in the future ^^

Well, your description of the problem is quite small and pure. Actually, there are two ways of achieving thing you probably want to achieve.

So, by the first you can have several docker-compose.yml files.

docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d

On the other hand, you can use extends option.

Rememeber, that some options in docker-compose.yml can be concatanated, as the following quote says.

For the multi-value options ports, expose, external_links, dns, dns_search, and tmpfs, Compose concatenates both sets of values:

The filename 'docker-composer.override.yml' is incorrect, you need to use 'docker-compose.override.yml'.
