Introduction

  • Briefly introduce the importance of CI/CD in modern application development.
  • Highlight the benefits of deploying Node.js Docker applications using aws command line and GitHub Actions.
  • Outline the steps that will be covered in the blog.

Prerequisites

  • aws account.
  • GitHub repository with your Node.js application.
  • Basic knowledge of Docker and GitHub Actions.

Enter fullscreen mode Exit fullscreen mode

2. Clone the repository 

git clone "git_url"
cd "repo_name"
Enter fullscreen mode Exit fullscreen mode

Create Dockerfile for Node.js Application

1. Inside the project directory, create a Dockerfile 

# Use Node.js base image
FROM node:16-alpine

# Set working directory
WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy application code
COPY . .

# Expose the application port (e.g., 3000)
EXPOSE 3000

# Start the application
CMD ["npm", "start"]
Enter fullscreen mode Exit fullscreen mode

Build and Run Docker Container

1. Build the Docker image 

docker-compose build (if you have docker-compose.yml)

docker run -d -p 3000:3000 --name node_structure node:20 tail -f /dev/null  
(if you do not have docker-compose.yml)

Also, docker-compose is (being) depricated in favor to the compose plugin.
Commands should be "docker compose..." not "docker-compose" with the plugin.

Otherwise, useful information for anyone who needs to add docker and git on a fresh linux install.

Why don't you install Compose from the packages as well? (apt install docker-compose-plugin)
