Is the mount for `.composer/auth.json` wrong?

[bennythejudge]

In this line in the docker-compose.yml file,

should:

     - ~/.composer/auth.json:/root/.composer/auth.json

be

     - ~/.composer:/root/.composer

and ~/.composer on the host contain a auth.json file (content according to this page?

When I tried my theory, the apache container would not start. Could you please explain this? This is clearly not an issue other than my lack of understanding/knowledge.

If you run composer as www-data user inside apache container, you need to link your auth file on your host to the www-data home folder

./yourhostauthjson.json:/var/www/.composer/auth.json

It kept having errors so I just commented out the file from the docker composer config.

ERROR: for apache  Cannot start service apache: error while creating mount source path '/host_mnt/c/Users/megab/.composer/auth.json': mkdir /host_mnt/c/Users/megab/.composer: permission denied
ERROR: Encountered errors while bringing up the project.

The permission denied thing, I needed to goto advanced security on the folder I was trying to use as a volume and give the docker-user group write access. (Windows Docker).

But then I still needed a login to run composer update in the end I changed it to use ./ rather than ~/ and made an auth.json with the login for my Magento2 keys. Phew~

Hello everybody, the mount can be configured in many different ways (or removed completely), it really depends on how you want to use it.

I wanted to mount only the auth.json but you could mount the whole .composer directory, for the root user or the www-data user, it really depends on how you want to use it.
