How to pull docker image from private docker repository in docker-compose.yml?

Question

How can I add the docker hub credentials in docker-compose.yml and pull the private image?

I want to pull 2 images from 2 different private repositories?

Answer 1

To push to or pull from private registry, you just need to add the registry’s location to the repository name. It will look like my.registry.address:port/repositoryname

On a fresh build it looks as follows

docker push localhost.localdomain:5000/ubuntu
Username (): user
Password:
Email (): user@pass.com

Then you can use docker login multiple times before running docker-compose, one for each registry, and they will stack.

Answer 2

You need to use docker login before invoking docker-compose:

https://docs.docker.com/engine/reference/commandline/login/

You would do something like this

services:
  s1:
    image: repo.foo.com/s1

  s2:
    image: repo.bar.com/s2

You would login once and Docker would remember your credentials:

docker login -u user1 -p pass1 https://repo.foo.com
docker login -u user2 -p pass2 https://repo.bar.com

and then you would run docker-compose as many times as you need.
