In order to launch a new EC2 instance, customers need to specify a lot of options, and it can be a slow and overwhelming task. It requires users to have an initial network stack (VPC-Id/Subnet-Id/Security-Groups), remote login, and many more. Often times, we require EC2 instance for adhoc testing for a short period of time without requiring complex networking infrastructure in place. AWS Simple EC2 CLI aims to solve this issue and make it easier for users to launch, connect and terminate EC2 instances with a single command
- Launch an instance using single command
- Connect to an instance using single command
- Terminate an instance using single command
- Interactive mode that help users to decide parameters to use
- Config file for more convenient launch
To execute the CLI, you will need AWS credentials configured. Take a look at the AWS CLI configuration documentation for details on the various ways to configure credentials. Alternatively, you can try out the AWS Simple EC2 CLI by populating following environment variables:
export AWS_ACCESS_KEY_ID="..."
export AWS_SECRET_ACCESS_KEY="..."
# Set default Region (optional)
export AWS_REGION="us-east-1"
brew tap aws/tap
brew install aws-simple-ec2-cli
