Lambda Function

This HTTP interface accepts 2 query parameters domain and concurrency. Returns Vec<Benchmark> serialized JSON.

Deplyoment can be automatically deployed to several regions with the included Terraform files. See Deploying.

Example Usage

Install cargo-lambda for a local Lambda runner.

# See other installation methods if you don't want to do it this way
pip3 install cargo-lambda

# Start a local runner
cargo lambda watch

Now you can query the local running instance:

~$ curl -X POST "localhost:9000/lambda-url/bootstrap/?domain=xgho.st&concurrency=3" | jq

Deploying

# Install cross for easier builds
cargo install cross

# Make a build targeting x86_64-unknown-linux-gnu
cross build --target x86_64-unknown-linux-gnu --release

# Create payload to upload
zip -r9 -j bootstrap.zip ./target/x86_64-unknown-linux-gnu/release/bootstrap

# Run terraform
terraform init
terraform apply

Test one of the endpoints like so:

$ curl -X POST "https://elex62ivj52ttxthgacylfksey0jkjkl.lambda-url.us-east-1.on.aws?domain=xgho.st&concurrency=3"
