@stefano honestly, I don't think that article is a lot about docker but more about a lack of good practice that is possible since someone started to throw docker over the fence.
The author provides solutions for each of the mentioned problems which sound like the breakdown between Dev and Ops is still waiting to take place. It looks like most of it could be solved by a wholesome "okay guys, let me help you out here and put my knowledge into your software projects".
@sheogorath Exactly. The general problem, in my opinion, is the (false) feeling of being able to do without system administrators, thinking that Docker (and related solutions) are the solution. Collaboration between the parties always remains the basis for a good result.
