cilium
Cilium is open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka.
A new Linux kernel technology called eBPF is at the foundation of Cilium. It supports dynamic insertion of eBPF bytecode into the Linux kernel at various integration points such as: network IO, application sockets, and tracepoints to implement security, networking and visibility logic. eBPF is highly efficient and flexible.
Prerequisites
- Kubernetes:
>= 1.16.0-0 - Helm:
>= 3.0
Getting Started
Try Cilium on any Kubernetes distribution in under 15 minutes:
| Minikube | Self-Managed K8s | Amazon EKS | Google GKE | Microsoft AKS |
|---|---|---|---|---|
 |
 |
 |
 |
 |
Or, for a quick install with the default configuration:
$ helm repo add cilium https://helm.cilium.io/
$ helm install cilium cilium/cilium --namespace=kube-system
After Cilium is installed, you can explore the features that Cilium has to offer from the Getting Started Guides page.
Source Code
Getting Help
The best way to get help if you get stuck is to ask a question on the Cilium Slack channel. With Cilium contributors across the globe, there is almost always someone available to help.
