Full Stack Deployment Using Docker Github Actions

Introduction:Deploying a Node.js application involves several crucial steps to ensure efficient and scalable performance. In this project, we aim to containerize a Node.js application and deploy it on an Amazon EC2 instance. The process begins by obtaining the Docker image source code from a Git repository. This source code is then built into a Docker image and pushed to the Docker Hub for centralized storage and accessibility. Once the Docker image is available on Docker Hub, we proceed to pull it from the repository and run it as a container on an Amazon EC2 instance. This approach leverages the power of Docker for containerization and the scalability of AWS EC2, ensuring a streamlined and reliable deployment process.

AWS Account: Make sure you have an AWS account. EC2 Instance: Create an EC2 instance and ensure you have SSH access. Docker: Install Docker on your local machine and the EC2 instance. GitHub Repository: Have a Node.js application hosted on GitHub.

Well- Have you ever been annoyed by rebuilding your code, reuploading the files to your server, restarting your app, and maybe even rebuilding the Docker image? That's the exact problem CD ("Continuous Deployment") tries to solve. With a proper CD pipeline set up, you don't have to worry about any of these things anymore. You can have a tool like GitHub Actions (or any other CI/CD tool) automatically build your code when you, for instance, push to a certain branch or create a new release. As developers, we often need to deploy applications to server environments. In this guide, I'll show you how to automate Docker container deployments using GitHub Actions, Docker Hub, and a simple cron job.

Whether you're new to Docker or looking to streamline your deployment process, this tutorial will walk you through both manual and automated approaches. Before building an Docker image, we setup a simple web server in main.py with two endpoints using FastAPI. This is just for demo purposes you can use whatever you like. First, let's create a minimal web server using FastAPI. Docker Stack Deployment Action is a versatile tool designed for effortless docker-compose and Docker Swarm deployments within GitHub Actions workflows. Below is a concise example demonstrating the utilization of this action:

Below is a comprehensive list of all supported inputs. Certain inputs are sensitive and should be stored as secrets. Specify the Remote Docker host like 203.0.113.0. Specify the Remote Docker SSH port if it's not the default (22), e.g., (2222). Explore the end-to-end process of setting up a continuous deployment workflow using Docker Hub and GitHub Actions—two powerful tools that, when combined, enable seamless automation from code commit to deployment. Continuous deployment (CD) is a pillar of modern software engineering.

By automating the journey from code commit to production, CD ensures faster delivery, reduced human error, and a streamlined development workflow. It empowers teams to ship small, reliable updates frequently, respond swiftly to feedback, and maintain a high standard of software quality. Beyond just speed, CD fosters a culture of accountability, collaboration, and continuous improvement. Developers gain confidence through immediate validation, businesses gain agility in meeting market demands, and users enjoy faster access to new features and fixes. When paired with continuous integration (CI) and continuous delivery, CD completes the trio that forms the backbone of DevOps and agile practices. It encourages test-driven development, infrastructure as code, and a mindset focused on automation and innovation.

Adopting CD isn’t just a technical shift—it’s a cultural evolution that brings your teams closer to building software that truly delivers. This guide will show you how to set up an automatic deployment pipeline using GitHub Actions. This pipeline will connect to a target server via SSH, update the Docker image, and restart the Docker containers. Automatic deployment ensures that your applications are always running the latest code with minimal manual intervention. Before you begin, ensure you have the following: To allow the GitHub Action runner to connect to your server, you need to create an SSH key pair.

Run the following command to generate an SSH key pair: Copy the generated public key to the remote server. Replace user and remote_server with your actual username and server address.
