'SSLError(SSLZeroReturnError during "docker compose build" (pip3 install -r requirements.txt)

[dciftci]

Hi Team,

I am currently stucked and having this error when I do execite docker compose build. I have a proxy settings and for testing purposes; I am successfully execute pip3 install -r requirements.txt in /iris-web/source - I installed all the dependencies.

But when I do execute build command, got this SSL/TLS error. I am trying to provision this VM under corporate proxy. Could you pleaes assist me about this issues? What should i do?

PS: I tried to create pip.conf and add our proxy there but did not fix it.

Are your proxy environment variables set? Additionally- may need to add your proxy certificate chain (if they rewrite SSL) to your certifi.pem file!

I guess the problem is related to specific python / pip proxy settings. I was able to fix it by bypassing the proxy settings and able to execute docker compose built successfully. But still no idea how to fix proxy things for pip/pthon step.

I'm closing this issue since the containers are now shipped prebuilt.
