Re: [Starcluster] EC2 AMI creation

Hi Justin and everyone,

Just tried running, and created a .starclustercfg that I think should be ok, but I get an error message:

mjp_at_mcp:~$ ./
/usr/local/lib/python2.6/dist-packages/pycrypto-2.0.1-py2.6-linux-x86_64.egg/Crypto/Hash/ DeprecationWarning: the sha module is deprecated; use the hashlib module instead
/usr/local/lib/python2.6/dist-packages/pycrypto-2.0.1-py2.6-linux-x86_64.egg/Crypto/Hash/ DeprecationWarning: the md5 module is deprecated; use hashlib instead
Traceback (most recent call last):
  File "./", line 162, in <module>
  File "./", line 55, in main
    EC2_PRIVATE_KEY = self.env_variables['EC2_PRIVATE_KEY']

In my .starclustercfg file, I've put the following line about my keyfile:

KEYNAME = mh-aws
KEY_LOCATION = /home/mjp/mh-aws.pem

Where mh-aws is the name of the keypair as it appears in my AWS console and /home/mjp/mh-aws.pem is the corresponding RSA private key. I thought the problem might have been the control-M characters in the PEM file, but I nuked those and still get the error. Any pointers?

I also applied for a research grant, which I just received, so I'm planning to start moving ahead with use. I have a question that is perhaps less starcluster-related: how do I modify the existing AMI and save it? And then how would I make star cluster launch that instance going forward?
