Need to understand how to run the agent in docker container

[sameerpjoshi]

Hi,

I got the docker container working with rfswarm-agent. Its also able to connect to the manager running on a public VM.

However , I see that its not able to run the tests. Not able to understand the reason. I think since the agent is able to be seen in agent list on manager side, its able to access the network port 8138 of manager.
`FROM python:3.11.0a7-bullseye

Please let me know what am I missing here.

Hi @sameerpjoshi,

Honestly i've not tried this yet myself (it is on the todo list) but it should work, and I heard from one of the other rfswarm users that they had it working, but I don't remember who.

You have the agent showing up in the manager, this is good, means the agent is running and communicating with the manager. so this means that the rfswarm components are all working.

I see from the screen shot that that 2 robots are assigned but none are running, hopefully that means the agent attempted to run the robot, remember it can take up to 10 seconds after the robot is assigned to the agent before the agent will attempt to start the first robot.

First thing to check, if you scroll to the right in the agents screen you will see a list of robot framework libraries that the agent recognised as being installed (the agent asks pip for this list) so first thing to check is that the libraries you need for your test are all there?

Next check the results directory, (depending on your scenario settings you may need to stop the test first), rfswarm agent will return the logs from robot framework back to the manager, if your not sure where the results directory is, check settings for the scenario and rfswarm.
In the results directory you should find a directory called logs, in this will be 1 directory per robot that attempted to run, open one of these directories and you should find the robot framework log.html file and .log which is the command line output from robot framework, if the robot failed to run, reviewing these files and you should get a clue as to why.

i'll check back here regularly to see how you got on.

Dave.

Thanks Dave for the reply. I really appreciate for the directions you gave. I checked the results directory on rfswarm manager and found this error in the log:
[ ERROR ] Parsing 'http:/xx.xx.xx.xx:8138' failed: File or directory to execute does not exist.
It seems that one "/" is missing somewhere. I am not sure where this error is coming from.
Had there been an issue in the agent reading the IP of the server, then the agent would have not connected to the server IP.
I tried escaping the "/" characters in "CMD" part of Dockerfile, still I see the same error in the log directory present on the rfswarm-manager.

This part of the error "File or directory to execute does not exist." is what doesn't make sense, I can't find anywhere that might be used in a file or directory, can you share the full log file? also which file did you find this error?
