Large Docker images slow deployments, waste storage, and increase vulnerabilities. Multi-Stage Builds optimize images by splitting the process into stages, keeping only essentials in the final lightweight image, improving speed, security, and maintainability.

🚨𝐖𝐡𝐚𝐭 𝐀𝐫𝐞 𝐌𝐮𝐥𝐭𝐢-𝐒𝐭𝐚𝐠𝐞 𝐁𝐮𝐢𝐥𝐝𝐬?
Multi-Stage Builds let you use multiple FROM instructions in a single Dockerfile, each representing a different stage. This allows you to compile or build your application in one stage and copy only the necessary output into the final, lightweight image.

✅𝐃𝐫𝐚𝐬𝐭𝐢𝐜𝐚𝐥𝐥𝐲 𝐑𝐞𝐝𝐮𝐜𝐞 𝐈𝐦𝐚𝐠𝐞 𝐒𝐢𝐳𝐞: By excluding unnecessary build dependencies, multi-stage builds keep only the essentials in your final image, shrinking its size by up to 50% or more.

✅𝐄𝐧𝐡𝐚𝐧𝐜𝐞𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲: A smaller image has fewer layers and dependencies, reducing the attack surface and the risk of vulnerabilities.

✅𝐅𝐚𝐬𝐭𝐞𝐫 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭𝐬: Smaller images mean quicker downloads and deployments, speeding up your CI/CD pipelines.

✅𝐒𝐢𝐦𝐩𝐥𝐢𝐟𝐢𝐞𝐝 𝐌𝐚𝐢𝐧𝐭𝐞𝐧𝐚𝐧𝐜𝐞: With separate stages for building and production, your Docker file becomes cleaner and easier to manage.
