Deploying an Erlang App on Flux Network with Deploy With Git

This is a minimal Erlang/OTP HTTP app ready to deploy on Flux Network using Deploy With Git.

How Flux Detects This App

Flux identifies Erlang projects by rebar.config. It then:

1. Reads the Erlang/OTP version from .tool-versions
2. Installs Rebar3 and resolves dependencies
3. Builds a production relx release with rebar3 as prod release
4. Starts the generated release in the foreground

The supervised server binds to 0.0.0.0 and reads the port from PORT. This sample has no third-party dependencies.

Deploy

Or configure it manually:

1. Go to orbit.app.runonflux.io.
2. Select this repository, the master branch, and project path erlang.
3. Select the free plan and set the application port to 8080.
4. Review and register the app.

The app will be available at a URL like https://YOUR-APP-NAME.app.runonflux.com.

Configuration

Variable	Description	Default
PORT	Port used by the HTTP server	8080
OTP_VERSION	Overrides the Erlang/OTP version in .tool-versions	28.4
REBAR3_VERSION	Overrides Orbit's Rebar3 version	Orbit default
BUILD_COMMAND	Overrides the automatic Rebar3 release build	—
RUN_COMMAND	Overrides relx release startup	—

Set the Flux application port to the same value as PORT.

Run Locally

rebar3 shell

Open http://localhost:8080. The health endpoint is http://localhost:8080/health.
