Tired of wrestling with server provisioning? Sumo!

Want to launch and manage persistent utility servers on EC2? ec2-run-instances got you down? Try this:

$ sumo create mybox
Created server mybox
$ sumo list
mybox          i-8a3d05e2  m1.small   ami-1515f67c
$ sumo launch mybox
---> Launch server mybox...   done (1.9s)
---> Acquire hostname...      ec2-75-101-254-61.compute-1.amazonaws.com (34.0s)
---> Wait for ssh...          done (3.1s)

Logging you in via ssh.  Type 'exit' or Ctrl-D to return to your local system.

root@domU-12-31-39-04-31-37:~#

Dependencies:

$ sudo gem install thor aws right_aws

Then create ~/.sumo/config.yml containing:

---
access_id: <your amazon access key id>
access_secret: <your amazon secret access key>

You’ll need Bacon and Mocha if you want to run the specs, and Jewler if you want to create gems.

Create a named persistent server:

$ sumo create mybox
Created server mybox

See config vars on the server record:

$ sumo info mybox
mybox:
   availability_zone:"us-east-1d"
   ami32:"ami-1515f67c"
   user:"ubuntu"
   key_name:"sumo"
   ami64:"ami-ab15f6c2"
   user_data:""
   security_group:"sumo"
   instance_size:"m1.small"

Set config vars before launch:

$ sumo set mybox --instance-size c1.medium

Create a static IP address and/or volumes:

$ sumo attach_ip mybox
$ sumo attach_volume mbox 50 /dev/sdh1

Launch an instance of the server:

$ sumo launch mybox
---> Launch server mybox...

You may want to spin down the server if it’s not in use:

$ sumo stop mybox

…and bring it up again later:

$ sumo start mybox

Sumo creates its own keypair named sumo, which is stored in ~/.ssh/keypair.pem. Amazon doesn’t let you upload your own ssh public key, which is lame, so this is the best option for making the launch-and-connect process a single step.

It will also create an Amazon security group called sumo, so that it can lower the firewall for services you configure via cookbook roles.
