Advice on building Docker images on Windows

Since the stable release of “Docker for Windows” in July 2016, you can work quite well with Docker on Windows. And its mostly the same workflows and user-experience as on Linux/MacOS.

However there are some things that could be improved (like sharing folders/drives between Host and Containers) and also some more not-so-obvious quirks.

standard_init_linux.go:175: exec user process caused "no such file or directory

Read on after the jump whats causing this and how to fix it and prevent it from happening again.

Using Dreamfactory 2.x as REST API with Docker

For a new project I’m working on as Systems and Platform Architect, we were looking for an comparably easy and fast to implement, yet scalable and reliable way to build a RESTful API for various services we need to expose to mobile device users via iOS/Android Apps aswell as internal services.

Fortunately there exists a great tool/framework which does alot of work for you nearly automagically. Its called Dreamfactory

Read on after the jump how Dreamfactory works and how we integrated it as BaaS into our docker-based PaaS.
