Be ready for the Dockerized future with the number ONE Docker + Kubernetes mega-course on Udemy. Welcome to the most complete and up-to-date course for learning and using containers end-to-end, from development and testing, to server deployments and production. Taught by an award-winning Docker Captain and DevOps consultant.
Just starting out with Docker? Perfect. This course starts out assuming you’re new to containers.
Or: Using Docker now and need to deal with real-world problems? I’m here for you! See my production topics around Swarm, Kubernetes, secrets, logging, rolling upgrades, and more.
BONUS: This course comes with Slack Chat, Discord Chat server, and live monthly YouTube Q&As with me!
“I’ve followed another course on (Udemy). This one is a million times more in depth.” “…when it comes to all the docker stuff, this is the course you’re gonna want to take” – Student Udemy Review
Why should you learn from me? Why trust me to teach you the best ways to use Docker? (Hi, I’m Bret, please allow me to talk about myself for a sec):
-
I’m A Practitioner. Welcome to the real world: I’ve got 20 years of sysadmin and developer experience, over 30 certifications, and have been using Docker and the container ecosystem for my consulting clients and my own companies since Docker’s early days. Learn from someone who’s run hundreds of containers across dozens of projects and organizations.
-
I’m An Educator. Learn from someone who knows how to make a syllabus: I want to help you. People say I’m good at it. For the last few years, I’ve trained thousands of people on using Docker in workshops, conferences, and meetups. See me teach at events like DockerCon, O’Reilly Velocity, GOTO Conf, and Linux Open Source Summit. I hope you’ll decide to learn with me, and join the fantastic online Docker community.
-
I Lead Communities. Also, I’m a Docker Captain, meaning that Docker Inc. thinks I know a thing or two about Docker and that I do well in sharing it with others. In the real-world: I help run two local meetups in our fabulous tech community in Norfolk/Virginia Beach USA. I help online: usually in Slack, Discord, and Twitter, where I learn from and help others.
“Because of the Docker Mastery course, I landed my first DevOps job. Thank you Captain!” – Student Ronald Alonzo
“There are a lot of Docker courses on Udemy — but ignore those, Bret is the single most qualified person to teach you.” – Kevin Griffin, Microsoft MVP
Giving Back: a portion of my profit on this course will be donated to supporting open source and protecting our freedoms online! This course is only made possible by the amazing people creating open source. I’m standing on the shoulders of (open source) giants! Donations will be split between my favorite charities including the Electronic Frontier Foundation and Free Software Foundation. Look them up. They’re awesome!
This is a living course and will be updated as Docker and Kubernetes features change.
This course is designed to be fast at getting you started but also get you deep into the “why” of things. Simply the fastest and best way to learn the latest container skills. Look at the scope of topics in the Session and see the breadth of skills you will learn.
Also included are Slack and Discord servers with 50k+ students for getting help with this course and continuing your Docker and DevOps learning with help from myself and other students.
“Bret’s course is a level above all of those resources, and if you’re struggling to get a handle on Docker, this is the resource you need to invest in.” – Austin Tindle, Course Student
