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}
    # App URL
    domain: ${BEETLE_APP_DOMAIN:-http://127.0.0.1:8080}
    # TLS configs
    tls:
        status: ${BEETLE_API_TLS_STATUS:-off}
        pemPath: ${BEETLE_API_TLS_PEMPATH:-cert/server.pem}
        keyPath: ${BEETLE_API_TLS_KEYPATH:-cert/server.key}

    # Message Broker Configs
    broker:
        # Broker driver (native)
        driver: ${BEETLE_BROKER_DRIVER:-native}
        # Native driver configs
        native:
            # Queue max capacity
            capacity: ${BEETLE_BROKER_NATIVE_CAPACITY:-5000}
            # Number of concurrent workers
            workers: ${BEETLE_BROKER_NATIVE_WORKERS:-4}

    # API Configs
    api:
        key: ${BEETLE_API_KEY:- }

    # Runtime, Requests/Response and Beetle Metrics
    metrics:
        prometheus:
            # Route for the metrics endpoint
            endpoint: ${BEETLE_METRICS_PROM_ENDPOINT:-/metrics}

    # Application Database
    database:
        # Database driver (sqlite3, mysql)
        driver: ${BEETLE_DATABASE_DRIVER:-sqlite3}
        # Database Host
        host: ${BEETLE_DATABASE_MYSQL_HOST:-localhost}
        # Database Port
        port: ${BEETLE_DATABASE_MYSQL_PORT:-3306}
        # Database Name
        name: ${BEETLE_DATABASE_MYSQL_DATABASE:-beetle.db}
        # Database Username
        username: ${BEETLE_DATABASE_MYSQL_USERNAME:-root}
        # Database Password
        password: ${BEETLE_DATABASE_MYSQL_PASSWORD:-root}

    # Kubernetes Clusters
    clusters:
        -
            name: ${BEETLE_KUBE_CLUSTER_01_NAME:-production}
            inCluster: ${BEETLE_KUBE_CLUSTER_01_IN_CLUSTER:-false}
            kubeconfig: ${BEETLE_KUBE_CLUSTER_01_CONFIG_FILE:-/app/configs/production-cluster-kubeconfig.yaml}
        -
            name: ${BEETLE_KUBE_CLUSTER_02_NAME:-staging}
            inCluster: ${BEETLE_KUBE_CLUSTER_02_IN_CLUSTER:-false}
            kubeconfig: ${BEETLE_KUBE_CLUSTER_02_CONFIG_FILE:-/app/configs/staging-cluster-kubeconfig.yaml}

    # HTTP Webhook
    webhook:
        url: ${BEETLE_WEBHOOK_URL:- }
        retry: ${BEETLE_WEBHOOK_RETRY:-3}
        apiKey: ${BEETLE_WEBHOOK_API_KEY:- }

# Log configs
log:
    # Log level, it can be debug, info, warn, error, panic, fatal
    level: ${BEETLE_LOG_LEVEL:-info}
    # output can be stdout or abs path to log file /var/logs/beetle.log
    output: ${BEETLE_LOG_OUTPUT:-stdout}
    # Format can be json
    format: ${BEETLE_LOG_FORMAT:-json}

And then run the application.

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

// OR

$ make run

// OR

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