Giving Bash a REST with OpenFaaS

[alexellis]

What would you like to let us know?

I'd like to see a blog post on writing functions with bash called: Giving Bash a REST with OpenFaaS

Context

Many DevOps/sysadmin users are comfortable with bash and CLI tools. Bash can make simple tasks and existing tools easy to use such as terraform and various cloud CLIs.

One of the challenges is visibility - showing people that this can be done.

The other is authentication - if you attach a cloud access token to a bash function, and anyone can provision a VM - that's a terrible idea. So how do you authenticate?

Thirdly, how do you take clean output from a bash function and filter that out so it can be used with another process or function?

The blog post should cover these topics and give examples using the openfaas bash template.
