Yay, the first Docker post I can understand. I just installed and used Docker today to get a simple web server running out of a VPS (which is also a first for me as I always used managed services like Heroku).

However, some aspects of Docker leave me with concerns that it may not be the tool for me. I tried installing the official node image and it downloaded hundreds of megabytes of other images (probably over a GB). Not that much of a problem on my VPS but absolutely unusable anywhere else in my corner of the world.

Looks like I'll have to create my own images and use my own private local registry to make use of Docker outside of my VPS.
