Amazon Web Services Demo
What I attempted to create here was a small tool that could spin up EC2 instances, list the instances that are active, and terminate them. I had a good deal of trouble getting the AWS SDK set up on the command line, but was able to get things working well in Eclipse using the Eclipse AWS SDK plugin.
To make the program something others could demo I turned it into a jar file. The jar file has a few different requirements though.
The first requirement is to set up group settings as follows:
On the aws dashboard under Network & Security select "Security Groups", click "Create Security Group" set Security Group Name to "bitcrusher" under the inbound tab select "Custom TCP Rule" under type, select "TCP" under Protocol, enter "22" in the port range, and set source to "My IP" then click "Create".
The second requirement is that credentials are set up as follows:
If the .aws directory is nonexistant: cd mkdir .aws cd .aws touch credentials nano credentials
Put in configuration information as: [default] aws_access_key_id = your access key id aws_secret_access_key = your access key
Usage is as follows: java -jar DemoRunner.jar Options: -l list instances, -g generate key, -i new instance, -t terminate instances
On first use generate a key, then use the same key name to create an instance. Follow instructions to connect. Then when finished terminate instances.
All of these instructions assume that you are on a linux based machine.
My main intention was to produce a tool to quickly spin up an EC2 instance with all of the information to ssh to that instance and then terminate the instance.
