Docker has revolutionized the world of software development by enabling containerization and efficient application deployment. However, running Docker containers as the default root user inside the container can pose significant security risks. To enhance the security of Dockerized applications, it’s essential to adopt best practices, including running containers as non-root users. In this blog, we’ll explore the benefits of running Docker containers as non-root users and provide a step-by-step guide on how to achieve it.

The Importance of Running Containers as Non-Root Users

Running Docker containers as the root user inside the container can lead to potential security vulnerabilities. If an attacker gains access to the container, they would have elevated privileges within the container and possibly the host system, posing severe security risks.

By running containers as non-root users, we can:

1. Reduce the attack surface: Limiting privileges mitigates the impact of potential security breaches.
2. Improve container isolation: Each container becomes more isolated, ensuring that a compromise in one container doesn’t affect others.
3. Follow security best practices: Running containers as non-root users aligns with the…
