Hi Alessio, thanks for your help.
Basically, the task is to write implement in the runtime an adapter that will
allow Knative images, that are basically simply http servers, to satisfy the
contract of the OpenWhisk actions.
There is already an implementation in Javascript here:
https://github.com/apache/openwhisk-runtime-nodejs/blob/master/core/nodejsActionBase/platform/knative.js
The contract is split in /init and /run behaviour
I already did the work for the init part although I have to change it to work
in the same way the Javascript implementation works. I will take care of it.
I would ask you to implement support of the /run part. Basically it means:
- accepting an http request in the root path
- create a single line json that encodes the values that an action expects, as
described here:
https://github.com/apache/openwhisk/blob/master/docs/actions-new.md (look for
activation)
- feed the json to the underlying action executor that is already running after
the initalization
- collect the answer and decode it in order to provide the expected http
answer. For a web action it must implement the web action contract as described
here:
https://github.com/apache/openwhisk/blob/master/docs/webactions.md
otherwise just return an action.
The javascript knative.js code should provide a good guidance on the details.
For anything else just ask, either here or on slack.
Go the same implementation here:

Hi I am a colleague of Michele and I would like to help you complete the
Knative support for actionloop, any indication will be appreciated, thanks,
