apptainer key pull

Download a public key from a key server

Synopsis

The ‘key pull’ command allows you to retrieve public key material from a remote key server, and add it to your keyring. Note that Apptainer consults your keyring when running commands such as ‘apptainer verify’, and thus adding a key to your keyring implies a level of trust. Because of this, it is recommended that you verify the fingerprint of the key with its owner prior to running this command.
