SUSE Openstack Cloud - sleshammer - pre/post scripts - pxe trigger
Posted on Wed 24 February 2016 in openstack • 1 min read
Enable root login for the sleshammer image
(it is used by the suse cloud as a hardware discovery image)
The sleshammer image will mount "/updates" over nfs from the admin node and execute the control.sh. This script will check if there are some pre/post-hooks and will possibly execute them.
root@admin:/updates # cat /updates/discovered-pre/set-root-passwd.hook
#!/bin/bash
echo "root" | passwd --stdin root
echo
echo
echo "ROOT LOGIN IS NOW ENABLED!"
echo
echo
sleep 10
Make sure that the hook set as executable!
SUSE Openstack Cloud supports only pre and post scripts. discovered is the state - discovery or hardware-installed should also work.
BTW: You can also create custom control.sh-script (and also hooks) for a node!
mkdir /updates/d52-54-00-9e-a6-90.cloud.default.net/
cp /updates/control.sh /updates/d52-54-00-9e-a6-90.cloud.default.net/
