Securing Containers, First Steps in Docker and Kubernetes

53 minutes

Bret goes through his top recommendations for securing container images, Docker containers and Kubernetes pods.

This is a tip-packed show where Bret lists much of what's documented in his courses, starting with the first steps you should take, and the bare security necessities that everyone should be doing. Then he covers more advanced security activities you should consider once the basics are covered.

Streamed live on YouTube on July 7, 2022.
