One of the nicest things about docker is reproducibility and containerisation. It is possible to run multiple applications which requires different environment on the same computer and make them live happily altogether. Although Raspberry Pi has ARMv7 instructions set, we still can run docker on it - we just need different images. One would be surprised there are some official images available on docker hub.
The configuration can be very simple - literally two commands in terminal, thanks to widely available devops tools such as docker-machine and ansible. Having this setup there won't be need to login to the RPi and perform any manual configuration per service anymore. Instead, services can be configured and deployed right from your computer.
If you don't have your Rasbperry configured yet refer to previous article for the initial setup.
