Connecting to the Eucalyptus Community Cloud with typica

Eucalyptus recently announced a public “cloud” sandbox known as Eucalyptus Community Cloud. It is a place where you can kick the tires to some degree and since they support a subset of the Amazon EC2 API, you can generally point EC2 tools at the ECC. This post will deal with using typica to interact with the ECC from within your Java software.

First thing to do is follow the ECC link above and create an account. If you already have an account to get into the Eucalyptus forums, you can login and apply for an ECC account. Once you get a confirmation e-mail and confirm the account, you’ll be able to login and get your access id and secret key. To do that, visit the ECC, login and select “show keys”, which reveal the QueryID (access id) and Secret Key. While you’re hear, you should also download credentials. This gives you a zip that contains something we’ll need later.


Jec2 ec2 = new Jec2(props.getProperty("aws.accessId"), props.getProperty("aws.secretKey"), true, "ecc.eucalyptus.com", 8773);
ec2.setResourcePrefix("/services/Eucalyptus");

Let me explain this code. The first line creates a new Jec2 object, that is configured to talk to the ECC. The “props” variable came from reading a property file containing the access id and secret key. The next parameter specifies SSL. Then, you pass the hostname for the ECC and the port it uses. After that, it would be business as usual. The EC2 sample code demonstrates some normal operations, and the API docs give a more complete picture.

When running the code, there’s a special option you’ll need as compared to using typica to talk to AWS. Since Eucalyptus clouds are generally installed with self signed SSL certs, you’ll need to specify a file that came with that credentials download in your java options. If you don’t do this, you’ll likely see a “SSLPeerUnverifiedException: peer not authenticated” error.


$ java ... -Djavax.net.ssl.trustStore=<path to files from credentials zip>/jssecacerts ... TestJec2
