- Added Dockerfile to containerize the Next.js application with Node 20.12.0 Alpine.
- Configured Dockerfile to set up the environment, install dependencies, generate Prisma client, and build the application.
- Added .dockerignore to exclude unnecessary files like node_modules, .next, .git, and environment files during the Docker build process.
