Not only a hype
Although you are sure to get new followers on social networks when using the docker hashtag (yes, we tried) it’s not only a hype. At least containers, not especially docker only.

But docker is the most used and most famous container solution at the moment. Big companies like spotify use docker in production at the moment and the number of adopters keeps growing.
I first used docker when it was in beta and liked the idea from beginning. At that time I hadn’t the chance to use it in production. I try to implement it as a vagrant replacement. Because of performance, no hypervisor overhead and so on. There had been a lot of bugs at that time. So after while I stopped using it, cannot exactly name a reason. Too much work and less time I guess 😉 It was in the winter I was moving I think.
Now docker seams pretty stable and has built a huge environment around it. swarm, compose, machine, just to name a few. As I am in charge of IT at a tech startup I thought about taking a look at docker, first for development, maybe later for production. Until now we have built a vagrant machine with ansible for every project we had. It works the most time, but as everywhere there are some issues at which docker could help. Also we are going the way to service based architecture, where docker also could work great. I’ll give it a try. And here on my blog and on my youtube-channel, I’ll keep you up to date.
