Cilium for Kubernetes 

Course & Training

Intensive Introduction to Kubernetes Network Security and Management with Cilium as CNI-Plugin.

This course provides a comprehensive introduction to Network Security and Management with Cilium on Kubernetes clusters. You will understand the basic principles of Cilium and CNI, get to know the Cilium architecture and concepts, and set up various network resources.

In-House Course:

We are happy to conduct tailored courses for your team - on-site, remotely or in our course rooms.

Content:


Together with the trainer, you will work on the following topics:

- Overview of CNI and Cilium
- Kubernetes Network Refresh
- Introduction to Cilium Architecture
- Cilium Setup and first Network Resources
- Cilium Network Policies
- Cilium based Ingress and Load Balancing
- Add and use Cilium Endpoints
- Service Mesh and mTLS with Cilium
- Cluster Connectivity
- Monitoring and Debugging
- Best Practices for Cilium Deployment
- Overview Cilium related Enterprise Products

You will not only get to know these concepts, but also implement them in practice.


Disclaimer: The actual course content may vary from the above, depending on the trainer, implementation, duration and constellation of participants.

Whether we call it training, course, workshop or seminar, we want to pick up participants at their point and equip them with the necessary practical knowledge so that they can apply the technology directly after the training and deepen it independently.

Goal:

After this course, you will be able to introduce Cilium as a CNI plugin in Kubernetes and effectively manage the associated network resources.


Form:

The course is well structured and consists of theoretical explanations and practical exercises. You will be accompanied by an experienced trainer who can answer questions related to Cilium and Kubernetes network security.


Target Audience:

This course is aimed at individuals who are already working with Kubernetes and wish to use Cilium for a broad range of networking topics in their clusters.


Requirements:

Basic understanding in the use of the command line.
Basic knowledge in Kubernetes.


Preparation:

Every participant will receive a questionnaire and a preparation checklist after registration. We provide a comprehensive laboratory environment for each participant, so that all participants can directly implement their own experiments and even complex scenarios.

More about Cilium



Cilium is an open-source software for networking, security, and observability that leverages eBPF technology. It provides traditional container networking interfaces (CNI), Kubernetes ingress and service implementations, as well as transparent encryption and service mesh functionality.




History


Cilium was developed in 2015 by Thomas Graf , who previously worked on the Linux kernel networking stack at Red Hat. The project emerged from the vision of using eBPF technology for cloud-native networking and security. The first version was released in 2017 and introduced the concept of identity-based security.


Development was significantly driven by the founding of Isovalent by Graf and Dan Wendlandt. A major milestone was the integration with Kubernetes and the introduction of Hubble for network observability. Support from companies like Google and acceptance into the CNCF as an incubating project in 2021 marked further important steps.


Today, Cilium is the default CNI for many major Kubernetes platforms, including Google GKE, Amazon EKS, and Rancher RKE. It has revolutionized how container networking is implemented through the use of eBPF. The introduction of service mesh functionality, Cluster Mesh for multi-cluster connectivity, and integration with projects like Envoy have made Cilium a comprehensive networking and security solution.
