sudo ironic-rootwrap /etc/ironic/rootwrap.conf iscsiadm -m discovery -t st -p <IP> hangs forever

[Waldemar Znoinski]

sudo ironic-rootwrap /etc/ironic/rootwrap.conf iscsiadm -m discovery -t st -p
in ironic_conductor container hangs forever.

strace on the process revealed it's waiting for input from the controlling terminal (/dev/tty).
It happens to wait for a password when running sudo commands.

To fix it sudoers file is required for ironic user, like so:
(ironic-conductor)[ironic@silpixa00385229 /]$ cat /etc/sudoers.d/ironic
ironic ALL=(ALL) NOPASSWD:ALL
