Getting started

To build the application locally, ensure you have the Rust compiler and Cargo package manager installed. Once installed, clone the repository and build the application using Cargo:

git clone https://github.com/homebrew-ec-foss/bal.rs
cd bal.rs
cargo build

For a production-ready build, you can use:

cargo build --release

How to Use

The Application

After building, the main executable will be located in /target/debug or /target/release based on the build command used. Navigate to the directory and type

Balrs help start

in the terminal to get a list of available commands.

Alternatively, from the root directory of Bal.rs, you can use:

cargo run help start

for the same result.

The Config file

The config.yaml file allows you to customize the Load Balancer settings:

• Load Balancer address: The URL of the Load Balancer(Default: http://localhost:8000)
• Algorithm: The load balancing algorithm to be used by Balrs(Default: round robin)
• Servers: List of server URLs to which Balrs can send requests
• Weights: List of weights of respective servers, used by weighted load balancing algorithms
• Max connections: List of the maximum number of connections each server is allowed to handle
• Timeout: Maximum time allowed for a server to respond before it is marked as dead
• Health check interval: Time interval at which server health checks are performed
