I have setup own git host which is just an nginx server with self-signed https which hosts a file system with git repositories. The repo is prepared as follows

cd /tmp/test-git
git clone --bare --shared https://github.com/redhat-rhods-qe/ods-ci-notebooks-main.git
cd ods-ci-notebooks-main.git
git update-server-info

Then, in Elyra I try to clone such a git repo but I'm getting an error (see the screenshot).

The url is definitely available, the cert is also available at etc/pki/tls/custom-certs/ca-bundle.crt

Workaround

Set the following env variable

GIT_SSL_CAINFO=/etc/pki/tls/custom-certs/ca-bundle.crt

Dev

1. Update the env var in Notebook-controller with GIT_SSL_CAINFO, so it adds it to all workbenchs

   2. Verify, by creating a workbench, and check if the env var is included.
