Overview

Docker is a platform that enables developers to build, share, and run containerized applications, simplifying the setup process and enhancing application security.

Pros

Simplifies application deployment by packaging applications and dependencies into containers.
Enhances security with hardened images that have near-zero CVEs.
Supports minimal and distroless images, reducing the attack surface significantly.
Offers extended lifecycle support for enterprise users, ensuring long-term security.
Facilitates consistent application behavior across different environments.

Cons

Can have a steep learning curve for those new to containerization.
Resource overhead can be higher compared to running applications directly on the host OS.
Complexity increases with orchestration tools like Kubernetes for managing multiple containers.
Networking and storage configurations can be challenging for beginners.
Requires a compatible host system to run Docker containers.
