Injecting certificate authorities to medusa container

I’m trying to configure medusa to use S3 compatible storage but am running into problems as we have self-issued certificates.
Does anyone know if it is possible to inject own ca files to etc/ssl/certs in the medusa container via k8ssandra operator?

The error message coming in the medusa container is:

Error([(‘SSL routines’, ‘tls_process_server_certificate’, ‘certificate verify failed’)],)

The hope was that something along these lines would work

volumes:
       - name: volume-ca-bundle
         configMap:
           name: config-trusted-cabundle
volumeMounts:
         - name: volume-ca-bundle
           mountPath: /etc/ssl/certs/ca-certificates.crt
           subPath: ca-certificates.crt
