Examples

eakl@hostname:~/ec2-starter $ ./setup_instance --defaults
The instance will be configured with the following options:

Name.............: eakl
Region...........: eu-west-1
Instance Type....: t2.micro
Image Id.........: ami-405f7226

Volume Name......:
Device Name......:
Volume Size......: 0
Volume Type......:
Delete Volume....:

User Data........:

Do you want to continue? (y/n [n])

or

eakl@hostname:~/ec2-starter $ ./setup_instance --user-data ./startup_data.txt
The instance will be configured with the following options:

Name.............: eakl
Region...........: eu-west-1
Instance Type....: t2.micro
Image Id.........: ami-405f7226

Volume Name......:
Device Name......:
Volume Size......: 0
Volume Type......:
Delete Volume....:

User Data........: ./startup_data.txt

Do you want to continue? (y/n [n])

The script generates two files. A delete script and a config file.

Output

Delete script.........: delete-vpc-<name>-<vpc_id>
Config file...........: .aws

The config file (.aws) contains all the information of your VPC and instance configuration. The delete script will delete your VPC, your config file and itself.

create_instance

This script will read your config file, start your instance and create an instance script:

eakl@hostname:~/ec2-starter $ ./create_instance
This instance will be created:

Name.............: eakl
Region...........: eu-west-1
Instance Type....: t2.micro
Image Id.........: ami-405f7226

Volume Name......:
Device Name......:
Volume Size......: 0
Volume Type......:
Delete Volume....:

User Data........: ./startup_data.txt

Do you want to continue? (y/n [n])

Output

Instance script...: instance

instance

eakl@hostname:~/ec2-starter $ ./instance
usage: instance <command>

commands:
   help                            Get help
   show                            Show instance information
   connect                         Connect to the instance
   upload    <local>   <remote>    Upload from local source to remote destination
   download  <remote>  <local>     Download from remote source to local destination
   start                           Start the instance
   stop                            Stop the instance
   reboot                          Reboot the instance
   delete                          Delete the instance

The delete option will terminate the instance (automatically deleted) and delete the instance script itself. Note that you must preferably call ./instance delete BEFORE ./delete-vpc-<name>-<vpc_id>.

manage_keypair

eakl@hostname:~/ec2-starter $ ./manage_keypair
usage: manage_keypair <command>

commands:
   --show                  Show Key Pairs
   --delete <key_name>     Delete <key_name>

This script uses my own environment variable $CONFIG pointing to my config folder where an aws folder keeps my AWS keypairs.
