  Although you're done with the workshop, there's still a lot more to learn about containers.
  Here are a few other areas to look at next.
  Container orchestration
  Running containers in production is tough. You don't want to log into a machine and simply run a
  docker run
  docker compose up
  . Why not? Well, what happens if the containers die? How do you
  scale across several machines? Container orchestration solves this problem. Tools like Kubernetes,
  Swarm, Nomad, and ECS all help solve this problem, all in slightly different ways.
  The general idea is that you have managers who receive the expected state. This state might be
  "I want to run two instances of my web app and expose port 80." The managers then look at all of the
  machines in the cluster and delegate work to worker nodes. The managers watch for changes (such as
  a container quitting) and then work to make the actual state reflect the expected state.
  Cloud Native Computing Foundation projects
  The CNCF is a vendor-neutral home for various open-source projects, including Kubernetes, Prometheus,
  Envoy, Linkerd, NATS, and more. You can view the
  graduated and incubated projects here
  and the entire
  CNCF Landscape here
  . There are a lot of projects to help
  solve problems around monitoring, logging, security, image registries, messaging, and more.
  Getting started video workshop
  Docker recommends watching the video workshop from DockerCon 2022. Watch the entire video or use the following links to open the video at a particular section.
  Docker overview and installation
  Pull, run, and explore containers
  Build a container image
  Containerize an app
  Connect a DB and set up a bind mount
  Deploy a container to the cloud
  Creating a container from scratch
  If you'd like to see how containers are built from scratch, Liz Rice from Aqua Security has a fantastic talk in which she creates a container from scratch in Go. While the talk does not go into networking, using images for the filesystem, and other advanced topics, it gives a deep dive into how things are working.
