Andy Kurth updated VCL-1000:
----------------------------
Description:
There are cases where it would be useful to be able to have scripts executed on
the management at various stages of reservations. For example, a script could
be executed to configure an external firewall or provision storage when a
computer is reserved. Whatever was configured specifically for the reservation
could be reverted when the reservation ends by another script.
We already have this functionality for scripts that get executed on the
computer ([VCL-564|https://issues.apache.org/jira/browse/VCL-564]).
The script would need access to information about the reservation. Since it
resides and is executed on the management node, the script could call mysql to
query the database. This isn't the safest way of handling things.
Another option could be to create a text file on the management node prior to
executing the script(s). The script could parse the text file to extract the
information it requires.
