Containerized Sanlock Daemon

Containerized Sanlock Daemon can be used to build a container image that runs sanlock.

The image repository: sanlock-daemon.

Prerequisite

Sanlock can clear the process within a specified time. Otherwise, the watchdog device is required to reset the host. If you do not have a hardware watchdog, you can enable softdog in the following ways.

cat >> /etc/rc.local <<EOF
#!/bin/bash
/usr/sbin/modprobe softdog
EOF

chmod +x /etc/rc.local

modprobe softdog
