In this initial step, we'll walk you through the process of installing the Nginx web server, which will serve as the cornerstone for our applications. Additionally, we'll cover configuring firewall rules to ensure that your server remains secure and accessible.
We need to create a custom Nginx configuration file (conf) for setting up a load balancer. This configuration file will be used to distribute incoming traffic to multiple backend servers, improving the availability and scalability of our application.
Task Details
Objective: Create a custom Nginx configuration file for a load balancer.
Requirements:
The Nginx configuration should define a load balancing strategy (e.g., round-robin, least connections).
It should specify the backend servers' addresses and ports to which traffic will be routed.
Proper error handling and logging should be configured in the Nginx conf file.
Security best practices should be followed in the configuration.
Expected Configuration:
Define the load balancer block with appropriate directives (e.g., upstream, server).
Specify the load balancing algorithm (e.g., round-robin, least_conn).
Configure error handling, logging, and security settings as needed.
Testing:
Test the Nginx configuration to ensure it works as expected.
Verify that traffic is distributed evenly among backend servers.
Documentation:
Document the purpose and usage of the custom Nginx load balancer configuration.
Provide any necessary comments within the configuration file.

Issue: Optimize Dockerfile for Next.js Application
Description
Context
Our Next.js application is currently being deployed using a Docker container. We want to optimize the Dockerfile for the application to create a smaller image, reduce build time, and improve caching efficiency.
Goals
Create an optimized Dockerfile for the Next.js application.
Minimize the size of the Docker image.
Leverage Docker build caching to speed up the build process.
Ensure the Docker image is secure and follows best practices.
Tasks
Optimize Dependencies
Review and update the package.json and package-lock.json files to minimize unnecessary dependencies.
Ensure that only production dependencies are installed in the Docker image.
Use a Slim Base Image
Update the base image to use a lightweight Node.js image (e.g., node:14-alpine).
Multi-Stage Build
Implement a multi-stage Docker build to separate the build environment from the production image. This helps reduce the image size.
Caching
Organize COPY commands to maximize Docker build caching. Copy only the necessary files and folders that have changed.
Security
Review the Dockerfile for any security vulnerabilities and apply best practices for securing the image.
Documentation
Update or create documentation on how to build and run the optimized Docker image.
Acceptance Criteria
The optimized Dockerfile successfully builds a smaller and efficient Docker image.
The image starts the Next.js application without errors.
Docker build caching is utilized effectively to reduce build times.
The Docker image follows security best practices.
Documentation is updated or created to guide users on building and running the optimized image.
Additional Information
Next.js Version: [Specify the Next.js version being used, if known]
Issue Title: Create Jenkinsfile for Docker Image Push to Docker Hub
Issue Overview
We need to set up a Jenkins pipeline for building and pushing Docker images to Docker Hub. This Jenkinsfile will automate the process of building the Docker image from our repository and pushing it to a Docker Hub repository.
Task Details
Objective: Create a Jenkinsfile for Docker image automation.
Requirements:
The Jenkinsfile should be designed to build the Docker image from our project's repository.
The pipeline should push the Docker image to a specific repository on Docker Hub.
Proper error handling and notifications should be implemented in the pipeline.
Securely handle Docker Hub credentials within the Jenkins pipeline.
Expected Workflow:
The pipeline should trigger automatically when changes are pushed to the repository.
It should use a Dockerfile present in the repository to build the image.
The image should be tagged and pushed to the specified Docker Hub repository.
Credentials:
Docker Hub credentials should be securely stored and retrieved in the pipeline.
Ensure that credentials are managed following best practices and securely stored in Jenkins.
Testing:
The Jenkinsfile should be tested to ensure it successfully builds and pushes the Docker image.
Documentation:
Provide documentation or comments within the Jenkinsfile to explain its purpose and usage.
Optional Enhancements:
Consider adding additional stages for testing or deploying the Docker image, depending on project requirements.
Create documentation for the Jenkinsfile used to push Docker images.
Explain the purpose and steps involved in the Jenkinsfile.
Steps to Complete
Create a Markdown (.md) file inside the appropriate directory.
Document the Jenkinsfile for pushing Docker images.
Provide clear explanations for each step in the Jenkinsfile.
Jenkinsfile Overview
The Jenkinsfile in our project is responsible for building and pushing Docker images to our Docker registry.
Look into the appropriate directory for the files.
