Hi Michele,

There is a PR we've submitted on Lean OpenWhisk (
There is also a blog here:

Would you like to look at it and see if it will be good enough for what 
you want to achieve.
The idea is to have OW (an actual one based on the Controller and Invoker 
upstream), but with a very small memory footprint.

Subject:        MiniWhisk: what you think?

Hello,  in the process of developing some examples for the goproxy, I 
realized I want a tool to make easier developing go actions locally. While 
it is generally acceptable to deploy your actions straight to the IBM 
Cloud for example when you code in Javascript (or Python) it is less 
desiderable for Go because compilation time in the cloud is not so fast as 
it is when compiled locally, and you have the additional time of uploading 
a binary that is generally bigger than javascript actions.

SO I ended up with this idea of the "miniwhisk". I am posting here to see 
if  it is acceptable or... there are better solutions.

My idea of the miniwhisk is a "single action " executor. It should work 
more or less this way:

$ miniwhisk /path/of/action  -runtime openwhisk/actionloop-go-v1.10:master 
 -watch *.go -build make -action demo

This command will launch the runtime 
"openwhisk/actionloop-go-v1.10:master"  using docker run, then will watch 
the files specified with "-w". When a file changes, it will execute the 
build command (-build) and then execute and "init" of the action runtime, 
post the action to the runtime as an init.

Additional (and most importantly) it starts a webserver that will listen 
to /path/of/action for GET and POST and will then translate requests in 
appropriate /run posts for the runtime.

Basically it is a tool to develop an action in go locally simulating what 
would happen when run in the real OpenWhisk.

How does sound the idea? Is it worth the effort?
