Question

I m probably having the most simple problem, but I m still a bit at my wits end. Basically my problems are related to this command:

euca-run-instances -k mykey emi-104915A8

As you know, when starting up instance in Eucalyptus, either through API (as I actually am) or with the command above, the key pair has to be created. If I have understood right, eucalyptus injects the public key of that key pair to the instance. Now there s a method in API (using typica, btw) for creating such a key pair, but I believe when using that it s not possible to get the private key, which I would be needing, since I d like to do some administrative stuff from external application.

So is it possible to get private keys through eucalyptus api? Or have you managed to find a good solution for injecting externally generated key pairs to instances? I m between just making my own images and either fooling around with custom-user parameters, or just making some general key pair and putting that straight to image.

I m just fooling around with Eucalyptus, and trying to get a hand of it, since I think it s best to get to know this cloud concept by trying to implement something on top of it :)

Answer 1

There is not much that can be done in this matter using Typica. I recommend creating the keypair by ssh-ing into the Cloud Controller and creating the keypair by euca-create-keypair command (all this through JAVA). You will get the private key as the output of the command. Save it into a file and carry on.

All the best !!!
