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.

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!

Dan Shechter
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!

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?

About the materials

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.
https://docs.docker.com/engine/security/security/

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.
