Hi Juan, Okay.. Thanks for your update. Also i found some sample cloud init scripts from here https://github.com/number5/cloud-init/tree/master/doc/examples and i tried the following scripts - type: foo/wark filename: bar content: | This is my payload hello - this is also payload - | multi line payload here - type: text/upstart-job filename: my-upstart.conf content: | Test file contents And run the start vm using the above script using cloud init and api, Could you please tell me where i can find the result of the above script ? I think the above script will create a file like my-upstart.conf -- Regards Shanil On Thu, Sep 4, 2014 at 1:56 PM, Juan Hernandez <jhernand@redhat.com> wrote:

Hi Juan,
Is there anyways to specify the custom script from a file in the xml ? ie, i have a script in a file called script.sh and i would like to include this script in the xml with the api call. Is there any methods for this ?
You can deploy files using cloud-init, and the run them using the custom script. Something like this:
<action> ... <initialization> <cloud-init> <files> <file name="/root/myscript.sh"/> <content><![CDATA[#!/bin/sh the content of your script]]></content> </file> </files> </cloud-init> <custom_script><![CDATA[runcmd: - sh /root/myscript.sh ]]></custom_script> </initialization> </action>
But I'm not a cloud-init expert, and I didn't test this, so I don't really know if the custom_script will run before or after the files are deployed. It makes more sense to run the scripts after deploying the files, but you will have to test it yourself.
The content of the files and the scripts has to be embedded in the XML document that you send to the RESTAPI server, there is no way to send an XML document and a separate file. Building this kind of XML document shouldn't be complicated if you use the CDATA syntax like in the example above.
Another thing that you may consider, if you have to run a complicated script or set of scripts, is to have them pre-installed in the template that you use to create the VM, then you just need to run them.

The custom script should go inside the "custom_script" element inside the "initialization" element:
<action> ... <initialization> <cloud_init>...</cloud_init> <custom_script>your custom script</custom_script> </initialization> </action>
