I am looking to access data on the CERN EOS system from within Pods on a baremetal Kubernetes cluster.
Is there any documentation on best practices for authentication to allow a pod to read and write data to the EOS system? I have attempted to use a keytab mounted as a secret but have been unsuccessful so far. Manual authentication using stdin is possible, showing that it is not a networking issue, but clearly such a manual method is not feasible for automated processes.
The error seen is shown below:
kinit: Keytab contains no suitable keys for host/<podhostname> while getting initial credentials
Any guidance or experience with similar issues would be greatly appreciated.
