In the OCI image spec file deletions are handled with special whiteout files... See: https://github.com/opencontainers/image-spec/blob/master/lay...

OpenFaaS is looking to be one of the most interesting FaaS frameworks. I like that it on the whole doesn't try force you into anything, its mainly just "Hi you know containers... great so you also know FaaS" It's good to see something that adds just the right amount of "Framework" to be useful, but not enough to feel bloated, or get in the way of just making stuff...

Ultimately "serverless" is always going to involve a computer of some sort somewhere, most likely a server ...

Functions as a Service is a much better description of the pattern... As an Ops person we often get a lot of requests for I need this (small) thing to happen when x... in the past we might have managed this with severs (probably called misc-{1..n}) running simple scripts as cron jobs...

I see "serverless" as a much better way to manage this sort of stuff ... and FaaS is especially good for this since anything that can go inside a container can be a function, so all the little bits of bash and perl and ruby and whatever script stuff just get chucked at this thing and just work...

I agree, I found this post really inspiring to go out and spend a few pounds on getting some equipment to try some of these things out... I might well be far more interested in some of the other applications, but this post is a cool idea of what can easily be done...
