I am trying to generate certificates using cert tools. while running below command I am facing issue. Please help me on this

create-certificate-template -c conf.ini

Error
govind@govind-VirtualBox:~/cert-tools$ create-certificate-template -c conf.ini
create-certificate-template: command not found
govind@govind-VirtualBox:~/cert-tools$

Did you run through the install instructions? create-certificate-template should be a valid command once you do. I find that creating a virtual env helps, not sure if you’re using one here.

Thanks aronnimg. NOw i am no more getting the issue. but different error now related to python. Is this anything to do with python version?

(venv) govind@govind-VirtualBox:~/blockchain/cert-tools$ create-certificate-template -c conf.ini

How did you solve it? I keep getting this:

During handling of the above exception, another exception occurred:

Hey!

I find that python and virtual environements can be a pain in the butt sometimes.
Docker can help you quite a lot here. I’ve created a docker image where all the configuration of Blockcerts, python and the dependencies are ready to go for cert-tools and cert-issuer.

You can pull the image:

docker pull florentdufour/cert-bundle

The link on Docker hub.

Take the time to understand how things work together,
Florent.
