Hello Dagster, I'm running 
dagit
, 
daemon
and one 
user-code
each in a Docker container. I use the default RunLauncher and Executor. Where exactly does the job and op computing takes place, in what container are the Python processes created • When I launch a job via Dagit? • When a job is requested by sensor or schedule?

I don't have the answer to your question, but I have a suggestion.. You can just create a dummy job like sleep(10000) and check the processes of your containers to find your answer.
In fact, you can also just create a file as part of your job so that you don't even have to check the processes. Something like 
Path("/find_me").touch()
should do the trick.

Indeed I can do that, that's a very good point 🙏

Hi Antoine - in both cases they’ll execute in your user code container

Hello @daniel, Thanks, very clear ! But the sensor and schedule code that request the run will run in the 
daemon
, right?
d
Dagit and the daemon will never run your code actually - that happens in the user code container too

Ok, so any credentials through env vars (like AWS) should only be in 
user-code
And 
dagit
and 
daemon
don't use the Dagster repository (the code), only the gRPC connection to 
user-code
.
Does it mean that a job with a config with a 
SourceString
pointing to an env var that I launch through 
dagit
will use the env var in the 
user-code
and not from 
dagit
?
d
that's right

Ok, thanks a ton 🙏
