Git on eolab: CA-certificates for custom git-servers

When using openEO Platform via JupyterLab and you want to track your code via git and your institution has a personal git server you might run into the issue that the server’s CA-certificate is not available on the virtual machine running the JupyterLab.
The error printed when trying to clone a repository will be:

server certificate verification failed. CAfile: none CRLfile: none

You need to download and add the certificate to your git repository to be able to access your institutional server.
You can do this via:
→ open a terminal with the JupyterLab launcher
→ Replace ‘myinstitution’ in the following code and run it:

openssl s_client -showcerts -servername -connect </dev/null 2>/dev/null | sed -n -e '/BEGIN\ CERTIFICATE/,/END\ CERTIFICATE/ p' > git-myinstitution-com.pem

→ add the certificate for a single user (also replace ‘myinstitution’):

git config --global http."".sslCAInfo ~/git-myinstitution-com.pem

→ This adds the following lines to ~/.gitconfig:

[http ""]
        sslCAInfo = /home/user/git-myinstitution-com.pem

Done! You can use git with the CA-cert of your institution from the openEO JupyterLab.
Please avoid other workarounds such as disabeling the ssl verification in the git config.
