In this video, learn about a new Cilium 1.15 feature - MD5-based authentication of BGP sessions!

In this video, learn about a new Cilium 1.15 feature - gRPC routing using Cilium Gateway API!

BGP support was initially introduced in Cilium 1.10 and subsequent improvements have been made since, such as the recent introduction of IPv6 support in Cilium 1.12 and Service IP Advertisements in Cilium 1.13. In Cilium 1.14, we introduced more BGP features, including: – BGP Timers Customization – eBGP Multihop – BGP Graceful Restart In Cilium 1.15, the following features are being added: – BGP Peering Security with MD5 – BGP Communities Support In this lab, the user will learn about both these new features and how they can simplify their network connectivity operations.

Learn how to connect your Kubernetes Clusters with your on-premises network using BGP. As Kubernetes becomes more pervasive in on-premise environments, users increasingly have both traditional applications and Cloud Native applications in their environments. In order to connect them together and allow outside access, a mechanism to integrate Kubernetes and the existing network infrastructure running BGP is needed. Cilium offers native support for BGP, exposing Kubernetes to the outside and all the while simplifying users’ deployments.

In this blog post, learn how you can use Cilium Gateway API to rewrite, redirect and mirror HTTP requests in Kubernetes!

Cilium and Azure Arc- solving the cluster manageability conundrum

In this short lab, you will learn about Gateway API, a new Kubernetes standard on how to route traffic into a Kubernetes cluster. The Gateway API is the next generation of the Ingress API. Gateway API addresses some the Ingress limitations by providing an extensible, role-based and generic model to configure advanced L7 traffic routing capabilities into a Kubernetes cluster. In this lab, you will learn how you can use the Cilium Gateway API functionality to route HTTP and HTTPS traffic into your Kubernetes-hosted application, including load balancing / traffic splitting and TLS passthrough or termination.

Correlate process-to-network data. Learn how Tetragon’s lightweight eBPF sensor captures K8s telemetry down to the binary, tying process to network data with no application changes. Decode DNS, TLS, HTTP, UDP, TCP , and more while matching to process ancestry information, all with Kubernetes identity-aware metadata (labels, pod names, etc). Read the solution brief and get under the hood with Tetragon.

Learn how to deploy Cilium to Red Hat OpenShift Clusters!

In Cilium 1.13, we introduced support for LoadBalancer IP Address Management (LB-IPAM) and the ability to allocate IP addresses to Kubernetes Services of the type LoadBalancer. Cloud providers natively provide this feature for managed Kubernetes Services and therefore this feature is more one for self-managed Kubernetes deployments or home labs. LB-IPAM works seamlessly with Cilium BGP: the IP addresses allocated by Cilium can be advertised to BGP peers to integrate your cluster with the rest of your network. For users who do not want to use BGP or that just want to make these IP addresses accessible over the local network, we are introducing a new feature called L2 Announcements in Cilium 1.14. When you deploy a L2 Announcement Policy, Cilium will start responding to ARP requests from local clients for ExternalIPs and/or LoadBalancer IPs. Typically, this would have required a tool like MetalLB but Cilium now natively supports this functionality. Try it in this new lab!

Ever since its inception, Cilium has supported Kubernetes Network Policies to enforce traffic control to and from pods at L3/L4. But Cilium Network Policies even go even further: by leveraging eBPF, it can provide greater visibility into packets and enforce traffic policies at L7 and can filter traffic based on criteria such as FQDN, protocol (such as kafka, grpc), etc… Creating and manipulating these Network Policies is done declaratively using YAML manifests. What if we could apply the Kubernetes Network Policy operating model to our hosts? Wouldn’t it be nice to have a consistent security model across not just our pods, but also the hosts running the pods? Let’s look at how the Cilium Host Firewall can achieve this. In this lab, we will install SSH on the nodes of a Kind cluster, then create Cluster-wide Network Policies to regulate how the nodes can be accessed using SSH. The Control Plane node will be used as a bastion to access the other nodes in the cluster.

With the rise of Kubernetes adoption, an increasing number of clusters is deployed for various needs, and it is becoming common for companies to have clusters running on multiple cloud providers, as well as on-premise. Kubernetes Federation has for a few years brought the promise of connecting these clusters into multi-zone layers, but latency issues are more often than not preventing such architectures. Cilium Cluster Mesh allows you to connect the networks of multiple clusters in such as way that pods in each cluster can discover and access services in all other clusters of the mesh, provided all the clusters run Cilium as their CNI. This allows to effectively join multiple clusters into a large unified network, regardless of the Kubernetes distribution each of them is running. In this lab, we will see how to set up Cilium Cluster Mesh, and the benefits from such an architecture.

Cilium, Azure Linux and Azure Kubernetes Service come together.

Achieving zero-trust network connectivity via Kubernetes Network Policy is complex as modern applications have many service dependencies (downstream APIs, databases, authentication services, etc.). With the “default deny” model, a missed dependency leads to a broken application. Moreover, the YAML syntax of Network Policy is often difficult for newcomers to understand. This makes writing policies and understanding their expected behavior (once deployed) challenging. Enter Isovalent Enterprise for Cilium: it provides tooling to simplify and automate the creation of Network Policy based on labels and DNS-aware data from Cilium Hubble. APIs enable integration into CI/CD workflows while visualizations help teams understand the expected behavior of a given policy. Collectively, these capabilities dramatically reduce the barrier to entry to creating Network Policies and the ongoing overhead of maintaining them as applications evolve. In this hands-on demo we will walk through some of those challenges and their solutions.

What is kube-proxy and why are platform teams moving from iptables to eBPF?

Kubernetes is built on the premise that a Pod should belong to a single network. While this approach may work for the majority of use cases, enterprise and telco often require a more sophisticated and flexible networking model. There are many use cases where a Pod may require attachments to multiple networks with different properties via different interfaces. With Cilium Multi-Networking, you can connect your Pod to multiple networks, without having to compromise on security and observability. Start this interactive hands-on lab to experience the benefits of Cilium Multi-Networking.
