Combining Cert-tool and cert issuer

I am looking to create a flask web app for creating and Issuing Certificate on Ethereum Testnet.

The problem is Cert-tools (creating Certificate) is outside Docker.
Cert-Issuer is inside Docker Container.

How should I combine the two? Any suggestions

I tried to bringing the Cert-Issuer module outside docker , But not able to run it.
I created a venv and ran python experimental --blockchain=ethereum
I am getting installation error for cytoolz

ERROR: Failed building wheel for pyethash
Running clean for pyethash
Building wheel for cytoolz ( … error
ERROR: Command errored out with exit status 1
cytoolz/dicttoolz.c:19:10: fatal error: Python.h: No such file or directory
19 | #include “Python.h”
| ^~~~~~~~~~
compilation terminated.

See complete error_log .

So should I try to resolve this error (if yes how) or move the cert-tools to Docker?
