cadre: configure apps
High-performance, minimal remote configuration service that's extremely simple to set up and use.
Configuration is backed by S3, updated from a human-readable web interface and
persisted to a file on disk. Multiple environments are supported and accessible
from a JSON web API. Plus, cadre is really easy to set up: just run a single
binary that contains the entire application, passing in an S3 bucket name.
The web server is written in Rust and can easily support over 80,000 HTTP/2 requests per second running on a consumer MacBook Pro, tested using vegeta. It's also horizontally scalable.
Template Syntax
Template values have keys that are prefixed with the * character. These values
are resolved at request-time.
aws:<NAME>: A JSON secret stored in AWS Secrets Manager. For performance, secrets are cached by the server for up to a minute.
All resolution of fields within templates is recursive. Additionally, you can optionally specify a default template, which is merged with the selected template whenever a configuration is requested.
Deployment
Run the cargo install cadre and use the cadre command. We also offer a
Docker image at ghcr.io/modal-labs/cadre, which is automatically built from
the Dockerfile in this repository on each release.
To perform a new release, check that you have write access to this GitHub
repository and the cadre crate on crates.io, then just run a single command:
cargo release.
