Deployment

On a Linux Server

Download the latest beetle binary.

$ curl -sL https://github.com/Clivern/Beetle/releases/download/vx.x.x/beetle_x.x.x_OS.tar.gz | tar xz

Create your config file as explained on development part and run beetle with systemd or anything else you prefer.

$ ./beetle serve -c /custom/path/config.prod.yml

Development

Beetle uses Go Modules to manage dependencies. First Create a prod config file.

$ git clone https://github.com/Clivern/Beetle.git
$ cp config.dist.yml config.prod.yml

Then add your default configs. You probably wondering how the following configs even work! let's pick one and explain.

The item mode: ${BEETLE_APP_MODE:-dev} means that the mode is dev unless environment variable BEETLE_APP_MODE is defined. so you can always override the value by defining the environment variable export BEETLE_APP_MODE=prod. and same for others

# App configs
app:
    # Env mode (dev or prod)
    mode: ${BEETLE_APP_MODE:-dev}
    # HTTP port
    port: ${BEETLE_API_PORT:-8080}
