You can build out functions in any programming language and then deploy them to your existing Docker Swarm. In this post we'll look at an experimental CLI for making that even easier Below is a quick example of how easy this is to do.

To deploy a function onto an OpenFaaS stack, you firstly must write the function itself. This is really easy and you can do it in any language which runs inside continue...
