This webinar will introduce you to Docker - why everyone's talking about it, what makes it so useful, and how developers and operators use it to improve their workflows. Attendees of this webinar will receive not only a high-level overview of Docker concepts and terminology, but a few practical examples that empower them to use Docker for their own projects immediately.


This webinar is part of Containers and Docker roadmap and accessible with standard subscription

Content Overview

The webinar covers these topics:

  • What are Linux containers?
  • What is Docker and how does it relate to Linux containers and orchestration systems like Kubernettes?
  • What are Docker Engine, Docker Compose and Docker Swarm?
  • Docker use of Linux namespaces
  • Overlay file systems and Docker volumes
  • Creating application stacks with Docker Compose
  • Container clusters using Docker Swarm
  • Deploying cluster application stacks with Docker Stack

The hands-on examples include:

  • Basic Docker CLI commands
  • Starting, stopping, killing and troubleshooting Docker containers
  • Running services in Docker containers
  • Building Docker images
  • Using Docker volumes
  • Using Docker Compose on a single Docker host
  • Simple Docker Swarm tasks
  • Using Docker Stack to create application stacks in Docker Swarm cluster

About the webinar

I think that few real world examples of how Docker is being used in production, could have been great. But all in all, very good into!

To the point - there are take-aways even if you are already familiar with the technology
Ernest Altbart
It was okay, but not up to the usual ipspace standards.

Thanks for another outstanding session. I did not know "docker system prune" existed. I am really looking forward the next session when you will cover docker networking.
perfect balance of depth. Thank you!
Fredrick Lowery
Very good grounding into Docker. I already have been looking at some future personal work in this area. The super-basic labs are great.

I have a few comments:

(1) Maybe this was covered and I missed it, but I would emphasize how every docker change makes a new image.

(2) Docker *seems* like a great use case for IPv6 (versus kludgy IPv4 NAT rules). If you agree, perhaps create a lab example?

I haven't any experience in Docker before and then two hours was a bit too short for me but was very interesting. I will watch the video again at my own pace now :-).
Very nice presentation. Thank you!

I'm still learning about Docker, but thus far I can provide the following.

Security: Make sure to cover how Docker containers share the kernel of the host in a secure and resource containing manner using kernel namespaces and control groups.

Networking: I know that Docker networking is still in development, but demonstrations of how containers communicate within a host or among hosts using a Docker-based overlay isn't especially helpful. It is required, but not what I'm really looking for. I need to know how to really tie containers to the outside world, how to provide L4-L7 services, and how to do it at scale for real world production environments. The demonstration was great for a lab environment, but I need to see how to make this work in the real world; including multi-tenancy.
