In xCAT 2.8 we are adding a mypostscript.tmpl, so that you can add any database attributes you want to be exported for the postscripts during the install or when you run updatenode. You can see the design here along with other performance enhancements. https://sourceforge.net/apps/mediawiki/xcat/index.php?title=Updatenode_Performance_Enhancements Lissa K.

For a long time it bugged me that postscripts don’t go through the same macro processing, until a colleague pointed out that it should be possible for postscripts to use curl to pull any attributes they need during the install. Very nice xCAT feature!! Here’s one possible postscript that could be called by other postscripts to load a node’s attributes into the current shell environment: /install/postscripts/getnodeattr: ATTRF=/var/log/xcat/attr.$NODE mkdir –p $(dirname $ATTRF) if [ ! -f $ATTRF ] ; then curl -k https://$MASTER/xcatws/nodes/$NODE?userName=wsuser&password=wspd > $ATTRF.xml || exit 8 fi # Convert # <tr><td>addkcmdline</td><td>sshd</td></tr> # to # export ATTR_addkcmdline="sshd" # sed -e '/^<[/]*table/d' \ -e "s/<tr><td>/export ATTR_/" \ -e 's;</td><td>;=";' \ -e 's;</td></tr>;";' < ${ATTRF}.xml > $ATTRF # load into the environment . $ATTRF || exit 7 To use this, one would call: “. /xcatpost/getnodeattr” from within a postscript. The wsuser user and policy must, of course, be set up first. Question 1. Is there any reason not to use curl and the REST API from postscripts during an install? Does this duplicate existing xCAT functionality? Question 2. It’s difficult to protect the “wsuser” password coded into /install/postscripts/getnodeattr. The file can’t be made read-only root, for example, because httpd needs to be able to read it. Is there a way to limit “wsuser” to GET calls?
