People who can use docker containers : here is the automated build for the daemon (node). I will help the network too. The trimmed image based on ubuntu 16.04 takes only 136MB. Running a node at this time need at least 2.2Go free on hard drive to store the blockchain but it will grow. For example, monero blockchain use today 33Go
Seems i ask this with
Windozxpert 
Did you have any tutorials for CentOS OS? or this will be same cuz both linux based?
Did you know how many bandwidth used by node ? Should i connect node to other nodes or to "IRD network". How this works ?
