This CLI tool can be used to load test a REST API endpoint.

First, you'll need to build the tool locally or pull the Docker image:

make build or docker pull nrfiacco/loadtest

Then, you can run the tool via:

./bin/loadtest [flags] [target]

or

docker run -v ./out:/app/out loadtest [flags] [target]

Note: you'll need to mount a local directory as a volume in the Docker container, and specify all paths relative to that container in your flags:

docker run -v ./out:/app/out loadtest --output_file out/output.csv https:test-url.com
