Documentation for docker deployment seems outdated

[georgr]

Description

When following the documentation "Deployment with Docker" under http://docs.etf-validator.net/v2.0/index.html the docker-compose up -d command fails:

docker-compose up -d
Pulling etfwebapp (iide/etf-webapp:)...
ERROR: The image for the service you're trying to recreate has been removed. If you continue, volume data could be lost. Consider backing up your data before continuing.

Continue with the new image? [yN]y
Pulling etfwebapp (iide/etf-webapp:)...
ERROR: pull access denied for iide/etf-webapp, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

It seems the iide/etf-webapp repository on docker hub does not exist anymore.

Expected behavior: Running etf webapp in docker container

Actual behavior: Docker container does not start
