Cilium has some terms with special meanings. These should all be covered throughout the documentation but for convenience we have also listed some of them below with short descriptions. If you need more information, please ask us on Slack. Feel free to extend this document with words you expected to see here.

A Cilium endpoint is one or more application containers which can be addressed by an individual IP address.
The identity of an endpoint is derived based on the labels associated with the pod or container.
Cilium labels are similar to regular container names / labels, the exception being that they can be key / value pairs.
A Cilium policy consists of a list of rules. The security policy can be specified in The Kubernetes NetworkPolicy format or The Cilium policy language.
