Docker has been on my list to learn for ~4 years Docker doesn't do anything shell scripts and zip files couldn't accomplish. The only thing Docker does is distinguish a class of human oriented activities, such that everyone is talking about the same goals, and explaining ideas about the same conceptual objects, at the same time, across all platforms (Windows, Linux, Apple, BSD, AWS, VMware, Vbox), disciplines and job roles. The DBA, the front-end JS developer, the sysadmin, the API developer, the SRE, the product team, the project managers, the tier one support and CRM call center, all of them are talking about the thing that standardizes virtual servers. It's not that docker is particularly useful or special, but more to the point, different people are talking about doing the same thing the same way, and hopefully in 50 lines or less, because pressing the power button on a working computer, and plugging in the network cable needs to be made that simple, so that people can stop tripping over themselves about that least important of pizza topping conversations.
