If backup target type is Ceph-based S3 with SSL:
If your backup target is ceph S3 with SSL and SSL certificates are self-signed or authorized by private CA, you must provide CA chain certificate to validate the SSL requests. You need to rename your CA chain cert file to s3-cert.pem and copy it into directory - nbos-cfg-scripts/redhat-director-scripts/redhat-director-scripts/ <RHOSP_RELEASE___Directory/puppet/nbos/files
cp s3-cert.pem /home/stack/nbos-cfg-scripts/ redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/puppet/nbos/files/
