Your trainer

Bret Fisher

Hey I'm Bret. Thanks for learning about me. I'm a freelance DevOps and Docker consultant, trainer, speaker, and Open Source volunteer working from Virginia Beach, USA. I've helped over 150,000 people learn Docker and DevOps tools and techniques.

I've been a cloud and datacenter ops/sysadmin for more than 20 years. For years I've been exclusive to containers and I help teams Dockerize their apps and systems, and improve their speed of deployment, resiliency, metrics, and awareness. All that DevOps-y stuff.

I'm also a Docker Captain and Code for America Brigade Captain. I run monthly meetups, speak at conferences, and love helping others. I'm obsessed with containerizing any app I see, and I'll likely talk your ear off about it next time we meet.
