Is is possible to inject files into a vm instance through heat. I am looking for a heat equivalent of "--file" command of nova boot.

Hi tried this but failed with No content found in the "files" section for get_file

2014-10-23 15:57:35.216 40973 TRACE heat.engine.parser File "/usr/lib/python2.7/site-packages/heat/engine/", line 373, in validate 2014-10-23 15:57:35.216 40973 TRACE heat.engine.parser result = res.validate()

do i need a specific file format? or specific path?

According to the documentation for OS::Nova::Server, you can use the personality property:

personality : Map

A map of files to create/overwrite on the server upon boot. Keys are file names and values are the file contents.

This is exactly equivalent to the nova cli --files option.

You can also create files via a cloud-init user-data script passed in using the user_data property.

Hi, I tried personality: Map, but what exactly is happening is, it is just copying the name of the file in the temp file.

for ex : personality: {"/etc/passwd": /root/passwd}

it will just copy the text "/root/passwd" into file "openstack/content/0000". it's not copying the content of original file

Please tell me, if I am doing anything wrong or what is the correct to way to execute it.

If you are launching with the heat cli then you can use the get_file function to include the contents of a local file when you create the stack, so you can try:

personality: {"/etc/passwd": {get_file: "/root/passwd"}}
