Open Stack

Cloud-init is also available on RHEL systems too. We're using it extensively
to contextualise VMs on Scientific Linux.

 

We've even tried a windows version but this is not as functional.

Hi Srikanth,

 

File Injection is not available through Horizon.

 

Atul is describing a different feature that can be used to achieve similar
results. The contents of "User-Data" will be accessible to the instance via
"http://169.254.169.254/latest/user-data" - Ubuntu ships with a tool called
cloud-init that makes use of this data if available. 

 

Eg One of the simple use cases for cloud-init is, if the data starts with
"#!", it will assume it's a shell script and download + execute it. This
can, in a roundabout way, be used to achieve similar results to the file
injection feature.


Thanks,
Kiall

Hi,

I am able to create an instance with the following command (along with File
Injection):

 

#> nova boot --file /root/inject.txt=/root/inject.txt --flavor=1
--image=4671e99b-1c01-42e8-94d6-2405a59bab57 testserver1

 

Now, what I need is to do the same from the Horizon. I will select a file to
inject from Horizon and Launch the Instance, it should inject that file.

 

Regards,

Srikanth.

Hi,

The test step followed for user-data as follows.

1. Got image from
http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-i386-
disk1.img

2. Booted it from Horizon and passed the script in the file

#!/bin/sh
mkdir /home/ubuntu/testdir

3. Logged in to the machine with

ssh -i <mykey.pub> ubuntu at IP

And i can see the directory created.


File injection via Horizon uses cloud-init and i have tested it on Ubuntu
12.04 i have no idea about other distributions.

You can file more about cloud-init here :-
https://help.ubuntu.com/community/CloudInit

And thanks, i will add this in the doc somewhere. :)

Hope it helps.

Hi,

I have some doubts regarding File Injection.
Can File Injection can be done through Horizon, while creating an Instance?
While creating an Instance from Horizon, a field called 'User Data' [text
area] is there. Is that field is related to File Injection? Can anyone tell
me, the values we need to give for 'User Data'?

Yes.


Cheers!!
