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.

Master Kubernetes with Learnk8s' Advanced Kubernetes workshops!

What should you expect?

- Learn how to architect and design clusters from the ground up (in the cloud or on-prem).
- Explore the Kubernetes internal component and how the system is designed with resiliency in mind.
- Deep-dive into the networking components and observe the packets flowing into the cluster.
- Hands-on labs to test the theory with real-world scenarios!
- And more.

The next course starts on the 19th of Feb (in Amsterdam, NL): https://learnk8s.io/amsterdam-advanced-february-2024

We also run in-person courses and corporate training: https://learnk8s.io/corporate-training

Containerized apps frequently require access to services running within and outside the cluster.

In this article, you'll explore how Cilium can be used alongside the security groups for EKS pods when running in chaining mode.

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.

Traditionally, EKS pods inherit the node's IAM role, contradicting least privilege principles by sharing one IAM role across multiple pods on the same node.

You can now use the EKS Pod Identity Agent to enable specific role assumption for pods.

Get ready for a 3-part, free educational program on building Kubernetes platforms with Learnk8s and Loft labs!

Each session comes with a webinar, code samples and a step-by-step article:

- Unit 1: Architecting Kubernetes clusters: single shared cluster or to each their own.
- Unit 2: Kubernetes namespaces offer no isolation, and how you can work around it
- Unit 3: Building a self-serve Kubernetes platform from scratch

You can register here (it's free): https://www.vcluster.com/building-a-multi-tenant-kubernetes-platform/

In this article, the author argues that Kubernetes needs a Long Term Release (LTS) plan in addition to keeping the current release cycle of one every 15 weeks.

Mat also cites the newly formed LTS workgroup as something to look forward to.
