I'm new to creating my own docker images. I've been following along with this guide. I've successfully built my by using docker-compose build in the root directory.

However, I encounter the same issue every time I try to run: docker-compose up

I get the following error:

Pulling postgresql (postgresql:latest)...
ERROR: pull access denied for postgresql, repository does not exist or may require 'docker login'

I've setup a docker account. I can run a postgresql image using the documentation.

I'm at a loss as to what to do. I'm thinking I should modify my Dockerfile for my project or the docker-compose.yml file, but I'm unsure.

Also, when I build my app, I get the following at the beginning:

postgresql uses an image, skipping

My docker-compose.yml file looks like:

web:
 build: .
 command: rails s -e production
 ports:
 - 3000 
 links:
 - postgresql
 - postgresql:postgresql.cloud66.local
 environment:
 - RAILS_ENV=production
 - RACK_ENV=production
 postgresql:
 image: postgresql

You may be running an outdated version of docker-compose.0

Also, your YAML seems to have an indentation error:

web:
 build: .
 links:
 - postgresql
 postgresql:
 image: postgresql

This should be:

web:
 build: .
 links:
 - postgresql
postgresql:
 image: postgresql

Maybe it was just a copy & paste error, because the error message implies it was parsed correctly.
