Add deep -dive containers section: docker and kubernetes

[seifrajhi]

Hello,
-We can add a deep-dive section about containerization, Docker, and Kubernetes:

• Detailed explanation of containerization and its benefits

• Overview of Docker: what it is, how it works, and its key features

• Hands-on demonstration of Docker commands and operations

• Kubernetes: what it is, how it fits in with Docker and containerization, and its architecture

• Kubernetes features such as:

• Deployment

• Scaling

• Load balancing

• Self-healing

• Discussion on security considerations and best practices for using Docker and Kubernetes in production.

• Explanation of Service Mesh and its purpose in a microservice architecture.

• Hands-on demonstration of setting up a Service Mesh on a Kubernetes cluster.

• Hands-on demonstration of backing up a Kubernetes cluster using tools such as Velero, Heptio Ark,

• Hands-on demonstration of using Karpenter to auto-scale your Kubernetes workloads, including setting up and configuring auto-scaling rules.

Thanks for the input here and raising the issue, the majority of what you have covered here is already in the 2022 edition and we have things like service mesh being covered later in the 2023 edition. We also covered storing and protecting data in 2022, but we could add detail regarding Velero.

Security has also been a big theme of the 2023 edition but appreciate that is a wider scope than just Kubernetes security, as in securing the platform. noted.

I like your idea around Karpenter though, this is on my list personally to learn more about in 2023.
