Description
This PR adds a
/health
endpoint alongside the metrics server, to allow it to be used as a readiness and liveness probe when deploying in Kubernetes environments. Currently, even though there exists a health endpoint, it is behind mTLS, which prevents it from being used as a readiness / liveness probe.Additionally, this PR addresses some clippy lints stabilized in Rust 1.87. This change affects the
src/app/tls.rs
file alone.I've also included some CI improvements in this PR.
I've tested it locally by calling the health endpoint at
http://localhost:6128/health
.
