- Run as non-root.
- Use a read-only root filesystem.

What if Kubernetes was so easy to install and manage to be foolproof?

In this KubeFM, Mat argues that GKE is the only Kubernetes managed service that offers a beginner-friendly and thought-through experience in running a Kubernetes cluster.

Follow Mat's journey to AKS, GKE and EJS and learn:

- How GKE autopilot can help you optimize costs and reduce underutilized node resources.
- How the GKE container-optimized OS prevents and eliminates an entire set of security misconfigurations in node management.
- How GCP's application of machine learning on the IAM permissions can help you gradually refine security permissions as applications are deployed.

In this tutorial, you will use the open-source tool Zarf to deploy a Podinfo with Flux application to a Kubernetes cluster.

Then, you will test the same deployment but air-gapped.

This project provides an OCI hook to generate seccomp profiles by tracing the syscalls made by the container.

The generated profile would allow all the syscalls made and deny every other syscall.

The best way to learn something is to break it or to build it yourself.

And that's precisely what Luca did to understand how Linux containers (and Docker) work: he built his own, Barco.

In this episode of KubeFM, you will learn:

- Why Linux containers "don't exist" but are the product of several Linux features you can put together and configure properly to get what we know as containers.
- How Kernel features such as cgroups and namespaces isolate a process.
- How you can use seccomp and capabilities to secure the container.
- How to make the right syscall from C to build your own container engine.
