Requirments:

There is a docker repository just created for this purpose.

You dont have to buy RaspberryPi, you can add this to a virtual machine and install a docker on that.

I like portainer. It makes docker much easier to work with. But you still need to understand some basic docker commands to get it going.

Just watch this course to get basic understanding of docker.


Docker for Beginners


What is portainer?

Portainer is a lightweight management UI that allows you to easily manage your different Docker environments. Portainer provides an easy and simple solution for managing Docker containers and Swarm services through a web interface.



Portainer is easier to deal if you dont like Terminal based docker.



You just stop/starts with widget buttons on a webpage. Much easier


Follow this link to install Portainer on linux machine.
