Once a LUKS volume is bound using clevis luks bind, it can be unlocked using any of the above unlockers without using a password.
$ sudo clevis luks unlock -d /dev/sda
For more information, see clevis-luks-unlock(1).
$ sudo dracut -f
Once Clevis is integrated into your initramfs, a simple reboot should unlock your root volume. Note, however, that early boot integration only works for the root volume. Non-root volumes should use the late boot unlocker.
Dracut will bring up your network using DHCP by default. If you need to specify additional network parameters, such as static IP configuration, please consult the dracut documentation.
$ sudo systemctl enable clevis-luks-askpass.path
After a reboot, Clevis will attempt to unlock all devices listed in /etc/crypttab that have clevis bindings when systemd prompts for their passwords.
