Using Docker

These instructions will get you a copy of the Docker project up and running on your local machine for development and testing purposes.

• Only pre-requisite is having docker and docker-compose installed
• Execute sh docker.sh in this directory (if you do not have permissions on the docker.sh, do chmod +x docker.sh)
• Server will start running at localhost:8000
• Ctrl+C to stop

Troubleshooting Docker

• Incompatible docker version
  • ERROR: Version in "./docker-compose.yaml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the services key, or omit the version key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
  • Fix: Update your docker toolkit
• Insufficient permissions
  • ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running? If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
  • Fix: Run it with sudo - sudo sh docker.sh

Note:- Docker project would start instances of Postgres, Redis and Django web app within the container as is shown below:-
