Jytte

jytte is a small http based application written in go with for demo and testing purposes.

Usage

The application will listen for requests on three endpoints:

/health will response with a http response 200 when the application is running

/metrics serves OpenMetrics (Prometheus) endpoint based on OpenTelemetry handler

/echo/ a simple echo server sending any incomming input back to the requestor

/entropy/ a server emulating having multiple dependencies on other services

Besides this the application exposes the Go pprof allowing runtime profiling and more. This is served on the default path of /debug/pprof.

Development

The project aims at following the best practices as described in project-layout.

Run the application locally simply use go run like so:

go run cmd/jytte/main.go

or from Bazel:

bazel run //cmd/jytte:jytte

Building local container image run:

bazel run --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64 //cmd/jytte:docker_image

Update Bazel dependencies generated from go.mod:

bazel run //:gazelle -- update-repos -from_file=go.mod -to_macro=deps.bzl%go_dependencies

Update the Bazel build files:

bazel run //:gazelle
