The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-

This can happen, and you should be prepared for it as well. This is also the article in this series to mention. In this series of tutorials we'll show you what you need to track, why you're tracking them, and what you need to do to deal with possible root causes.
We'll show you each indicator, how to track it, and what you can do to take action. We will use different tools to collect and analyze this data.

This poses a problem, if some of the pod's collections (called backends) are other pods of the cluster (called frontends), how do these frontends find and always know which backe

What is PodPods are the smallest deployable units that can be used to create and manage kubernetes calculations. A pod represents a process that runs in a cluster.Pods are like pea pods, which consist of one or more containers (such as Docker containers) that share container storage, network, and container run configuration items. The containers in the pod are always dispatched at the same time and have a common operating environment. You can think of
