I’m trying to debug a

meltano --log-level=debug install

from inside a docker build process. I have successfully install version 3.1.0 prior to this step but the only relevant log that comes out of it is:

[info     ] Logged pip install output to /opt/dagster/app/meltano/.meltano/logs/pip/extractors/tap-salesforce/pip.log
Extractor 'tap-salesforce' could not be installed: Failed to install plugin 'tap-salesforce'.

I can’t access that

pip.log

from inside a docker build process, so how do I debug?

I have this in https://github.com/meltano/meltano/issues/8170 tbh I've just gone back to an older version of meltano to debug the pip issue 😢

hmmm. that’s unfortunate, cuz I need a solution sooner than that’ll get fixed … 😢

Go back to an old version of meltano (2.18 works)

I can’t use an older version because I need the UI removal that happened in 3.0.0

You can hop into the docker container and run the instlal yourself (then cat the pip dir)

ah, good point, don’t know why I didn’t think of that facepalm

I completely understand

that makes me feel better lolsob

Do you guys think it'd be a good idea to document how to use volumes to save Meltano's logs to the host filesystem when running in docker?

It wouldn’t hurt, but in my case it wouldn’t have helped because this wasn’t running in a container per se. It was occurring during the docker build process.

Hi @josh_lloyd. I'm having this same issue. How did you resolve it?

I did just what visch suggested. I built the image all the way up until the step before installing and then I ran and exec’d into the container and ran the install from inside the container. Figured it out from there (though I don’t remember exactly what the issue was anymore).
