• Batch : DO8WD-E

Note : Due to the application's lack of support for the latest Node.js version, I've chosen to utilize Node.js 14

• Using a Dockerfile, the application was built on a Node.js base image, and the artifacts were then copied to an Nginx image for web access.
• A Docker-compose file has been created to manage and run the built application.

• Bash script was created to automate the build and run processes using Dockerfile and Docker-compose files.

• Branch named 'dev' was created in Github repository using Git.

  git branch dev

• The application code has been pushed to the 'dev' branch.

• A .gitignore file has been created to avoid pushing unnecessary files.
• A .dockerignore file has been created to avoid pushing unnecessary files while dockerizing.

• Repository named 'dev' and 'prod' was created in docker hub with public and private access, respectively.

• Docker Hub with image
