And regarding actionloop specifically: when I looked at it last year, it seemed that the generic actionloop container would just need a flag (such as an environment variable) to enable debugging, which wskdebug could set automatically if it sees an actionloop based kind. Then each specific actionloop language container would use this to run the language runtime inside the container with debugging enabled and open a debug port, which would also be passed through as env var.
Environment variables are good for this, as this makes it impossible to change them in a real production Openwhisk environment (as only the openwhisk invoker can set these, and they would only have an effect on start of the container/app). While wskdebug can easily set these as well.

I guess this isn't really a scenario that wskdebug is built for, because in this case you have full control over what happens in that local openwhisk and debug ports of action containers can be visible in your host. IIUC this might be what you are doing already - not sure I fully grasped that however. wskdebug is generally meant for debugging when you are using a remote Openwhisk (say IBM Cloud or Adobe I/O Runtime) and you have no other choice. Many/most action developers will not themselves be able to spin up a local openwhisk, and sometimes you really need to debug in the real environment, not a local copy. But ignoring that, I wonder what exactly is failing when you run wskdebug inside a container? In theory it should be feasible. Might be something that can be fixed.

My setup is: Standalone OpenWhisk running in a docker container, because the debugger (and the IDE) runs in another docker container. I need this setup because I want to provide a very simple installation, a wskide command that will setup the development environment. If I run the debugger from the standalone openwhisk works. But I have problems to add also the IDE that requires also node. So the prerequisites to run the whole thing would be a java of a given version, a node of the right version and docker. So I decided to go for a full dockerized solution. I have a launcher, written in go, that starts standalone openwhisk running in a docker container, and another container with the debugger and the editor (theia). In this setup, wskdebug does not work. It tries to do something with docker and does not work. I was unable to understand what is wrong, I tried to read the code but I do not follow it. For this reason I simply put an action in debug mode (using the runtime) and then I connected from the ide. It is more straightforward. There are still some issues to sync. But everything is open for discussion, I am more than happy if I can re-use wskdebug. -- Michele Sciabarra mich...@sciabarra.com ----- Original message ----- From: Alexander Klimetschek <aklim...@adobe.com.INVALID> To: "dev@openwhisk.apache.org" <dev@openwhisk.apache.org> Subject: Re: Preview of a OpenWhisk IDE & Debugger... and an help request Date: Tuesday, February 04, 2020 5:02 PM Hi Michele, please note that wskdebug [1] is a debugger for any kind. Nodejs has the best out of the box support since that’s what we are exclusively using right now. Other languages can already be supported using the right command line arguments (ports, docker command etc), which is how Java worked. Given this new __OW_DEBUG_PORT env variable, it can be set with wskdebug using —dockerArgs. Contributions are welcome to make this more automatic based on the kind/image version of the action :-) FYI, On the contribution front, I will work on the legal documents this or next week.

I guess the difference is that you are doing this using the standard nodejs runtime while I am doing the same using the goproxy. I am sure it is also similar to the adobe/wskdebug that I tried to use, and works but it specific to the node and java runtimes, without actionloop. My goal is to get the debugger for the "other" languages, most notabily typescript python and go. Let's discuss on the call to see how we can align efforts. -- Michele Sciabarra mich...@sciabarra.com ----- Original message ----- From: Dominic Kim <style9...@gmail.com> To: dev@openwhisk.apache.org Subject: Re: Preview of a OpenWhisk IDE & Debugger... and an help request Date: Monday, February 03, 2020 10:52 AM Thank you for the details. It seems what you are tying now is similar with our approach and can be aligned with ours too as it is generic like you said. We enabled the debugging of Nodejs runtime with chrome DevTools protocol https://chromedevtools.github.io/devtools-protocol/. Our UI communicates with the real remote OW deployment. We implemented one proxy server to correlate a debugging session with a corresponding action container. Since each action container is not exposed to public, we also have a bridge component on each invoker machine for location transparency. If I understood correctly, each container will connect to the IDE in a reverse way in your version and similarly it connects to the proxy via bridge in our version. SoI think two versions can coexist, if we make the interface extensible. Maybe I can share more details at this interchange call.
