The HPE Cray EX system signs RPMs to provide an extra level of security. Use the following procedure to import a key from either My HPE Software Center or a Kubernetes Secret, and then use that key to validate the RPM package signatures on each node type.
The RPMs will vary on compute, application, worker, master, and storage nodes. Check each node type to ensure the RPMs are correctly signed.
Retrieve the signing key required to validate the RPMs.
Use either the My HPE Software Center or Kubernetes Secret method to find the signing key.
My HPE Software Center:
Download the signing key.
ncn-mw# curl LINK_TO_KEY_IN_My_HPE_Software_Center
Kubernetes Secret:
Find the key and write it to a file.
ncn-mw# kubectl -n services get secrets hpe-signing-key -o jsonpath='{.data.gpg-pubkey}' | base64 -d | tee hpe-signing-key.asc
