Be ready for the Dockerized future, where nearly all software is developed and deployed in containers. Welcome to the most complete and up-to-date course for learning and using Docker end-to-end, from development and testing, to deployment and production. Taught by a 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, secrets, logging, rolling upgrades, and more.
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 and Twitter, where I learn from and help others.

Some of the many cool things you'll do in this course:

Edit web code on your machine while it's served up in a container
Lock down your apps in private networks that only expose necessary ports
Create a 3-node Swarm cluster in the cloud
Use Virtual IP's for built-in load balancing in your cluster
Optimize your Dockerfiles for faster building and tiny deploys
Build/Publish your own custom application images
Create your own image registry
Use Swarm Secrets to encrypt your environment configs, even on disk
Deploy container updates in a rolling always-up design
Create the config utopia of a single set of YAML files for local dev, CI testing, and prod cluster deploys
And so much more...

After taking this course, you'll be able to:

Use Docker in your daily developer and/or sysadmin roles
Make Dockerfiles and Compose files
Build multi-node Swarm clusters and deploying H/A containers
Build a workflow of using Docker in dev, then test/CI, then production with yaml
Protect your keys, TLS certificates, and passwords with encrypted secrets
Keep your Dockerfiles and images small, efficient, and fast
Develop locally while your code runs in a container
Protect important persistent data in volumes and bind mounts
Lead your team into the future with the latest Docker container skills!
