[galaxy-dev] Cloudman and parameterized launching

[Brad Chapman]

Scott;
The user passes in the AWS access and secret keys in the user-data
box. This page has all the details about the YAML format CloudMan
expects (in step 2 of the detailed steps):

http://wiki.g2.bx.psu.edu/Admin/Cloud

You can pick the passed in user-data up from any instance with
this url:

http://169.254.169.254/latest/user-data

and parsing it. CloudMan uses a script (in Python) that runs at boot:

https://github.com/chapmanb/cloudbiolinux/blob/master/installed_files/ec2autorun.py#L35

with a little upstart script in /etc/init/cloudman.conf:

https://github.com/chapmanb/cloudbiolinux/blob/master/cloudbio/cloudman.py#L8

Once you've got it in your script you can parse and use it as you need.
Hope this helps,
Brad
