Redesign docker environment

Issue Description

docker-compose.yml is outdated, leading to broken installation of the project.

As discussed with @systimotic in Gitter room, I’ll build relevant development environment for the project.

Tasks to do:

• Rename docker-compose.yml to sample.docker-compose.yml and add docker-compose.yml to .gitignore - this way developers will be able to copy sample file and create their own docker-compose.yml files, giving them flexibility to make changes as they need.

Define docker-compose services:

• database service - mongo
• web server - node
• mail system - mailhog

Installation process:

• Follow the project installation steps and make sure it leads to working instance of the project inside Docker environment.
• Document everything under project’s installation section.

Perfect. Thanks a lot for taking this up.

Hi @raisedadead,

Thanks for the info.

I don’t expect any code changes for this issue, here is what I will need to change:

1. Rename docker-compose.yml to sample.docker-compose.yml;
2. Add docker-compose.yml to .gitignore;
3. Add a small sub-section in CONTRIBUTING.md describing docker installation steps.

There is no need to publish images to the registry because I don’t expect that we will need any custom built images, just having sample.docker-compose.yml in our repo should be enough.
