helixml / dagger

Step-by-Step Guide

Prerequisites

Ensure the following tools are installed on your production server:

  • Go (version compatible with the project)
  • Git

Step 1: Clone the Repository

Clone the helixml/dagger repository to your local machine or production environment.

git clone https://github.com/helixml/dagger.git
cd dagger

Step 2: Build the Project

Navigate to the project root and build the Go application. The Golang Module name is main, which will influence the output of the build process.

go build -o dagger main.go

This command compiles the code and outputs an executable binary named dagger.

Step 3: Configure Environment Variables

Before deploying, configure any necessary environment variables required by your application. This can often include database connection strings, API keys, and other configuration settings.

You can set environment variables directly in your shell or by creating a .env file (if supported).

export DATABASE_URL="your_database_url"
export API_KEY="your_api_key"

Step 4: Prepare the Production Environment

Ensure that your production environment is secured, up-to-date, and properly configured to run the Go application. This may involve setting up necessary dependencies, firewalls, and accessing logging and monitoring services.

Step 5: Start the Application

Run the application in the background or as a service. 

nohup ./dagger &

The nohup command allows the process to continue running after the terminal has been closed. Ensure to handle proper logging either through stdout or by using tools like systemd or a logging service.

Step 6: Monitor and Maintain the Application

Once deployed, continuously monitor the application for any issues. Handle logs using an appropriate logging system. Ensure that health checks are configured, either through a load balancer or standalone monitoring tools.

# Example of checking logs
tail -f /var/log/your_application.log

Step 7: Update the Application

For any updates, pull the latest changes from the repository:

git pull origin main

Rebuild the application:

go build -o dagger main.go

Then restart the application to reflect the changes.

pkill -f dagger  # Terminate the existing instance
nohup ./dagger &  # Start the updated instance
