How do you enforce Container Security in production deployments?

Explanation & Concept

Key container security practices: 1. Never run containers as root (`USER nonroot`). 2. Set filesystems to read-only (`--read-only`). 3. Drop all Linux capabilities except what is needed (`--cap-drop=ALL`). 4. Scan images for vulnerabilities using tools like Trivy or Snyk.

Code Example

bash

# Run secure container with dropped capabilities and read-only root
docker run -d \
  --read-only \
  --cap-drop=ALL \
  --cap-add=NET_BIND_SERVICE \
  --security-opt=no-new-privileges:true \
  my-app

How It Works & Key Takeaways

Dropping Linux capabilities prevents attackers who breach the container process from escalating privileges or manipulating the host kernel.
