This is a quick and dirty tool to load test any given service/URL. You can spawn EC2 instances (in multiple regions) at will and hit any URL repeatedly from them and obtain the resulting output on your console.
Why did I create this? Mostly because I couldn't get beeswithmachineguns up and running quickly, so I thought why not create one. It's always great to have alternatives!
Though I created this to simulate real world traffic for my apps, but this can be used to execute any commands on remote EC2 instances by just changing the command in config file.
You can either run the ruby script directly (after installing dependencies), or use the dockerized version instead.
- Clone the repository locally
- Add all key pair .pem files (for different regions) to the config directory. In case you don't know what I am talking about, try and figure it out here
- Create an AMI for each region (spawn an EC2 instance with Linux and install apache bench, SSM agent and any other tool you need on it. Then generate an image from it). You'll need it in config file
- Create a role which enables SSM (Amazon EC2 Systems Manager) to access your EC2 instances. If you are unable to figure this out, troubleshoot here. You will need to specify this role in config file
- Add details to config.yml
docker build -t loadtest .docker run -t loadtest- docker ps
- Use the container id from previous command to log in to docker shell:
docker exec -it <contaner id> bash ruby load_test.rb
- Clone the repository locally
- Add all key pair .pem files (for different regions) to the .ssh directory in you home directory (~/.ssh/)
- Create an AMI for each region (spawn an EC2 instance with Linux and install apache bench, SSM agent and any other tool you need on it. Then generate an image from it). You'll need it in config file
- Create a role which enables SSM (Amazon EC2 Systems Manager) to access your EC2 instances. If you are unable to figure this out, troubleshoot here. You will need to specify this role in config file
- Add details to config.yml
gem install aws-sdkruby load_test.rb

Be careful with extra spaces and tabs while editing the yml file.

You can add more regions to the yml if you want to, in the same format. Additionally you can run any command on the EC2 instance by changing it in the config file. You can execute multiple commands using the && separator as well.
The details for all the other config values have been provided above.
Use this as you want in an ethical manner. I hope that you are not going to use this for a DDOS attack by creating huge amounts of traffic for a website which is not yours.
Additionally please verify that all your EC2 instances have been successfuly terminated after the script finishes running. I don't want to be cursed for your AWS bill due to some unhandled exception in the code ;)
Do What the Fuck You Want to License! Just that I do not accept any liability arising from it.
