Kubernetes Networking | Kubernetes Container Networking | Kubernetes Pods and Containers | Kubernetes Container Communication | Kubernetes Container Port ► Subscribe To Me On Youtube: https://bit.ly/2z5rvTV In this video I cover one part of the broader Kubernetes Networking topic, which is container communication inside pods. Considering Pods mostly contain only 1 main container, I start by answering the question of why having a Pod as an abstraction over container is such an important concept in Kubernetes. I show how container port mapping is a problem with hundreds of containers, specifically how to allocate ports without getting conflicts. How this compares to Pods and how Pods solve this port allocation problem. In addition, I show you in which cases you would need to run multiple containers in one pod and how these containers communicate with each other inside this pod. ❌ Correction for 6:15 in the video: Vagrant is NOT a container runtime alternative. K8s lists some of the alternatives here ► https://kubernetes.io/docs/setup/production-environment/container-runtimes/. ▬▬▬▬▬▬ Complete Kubernetes Networking Course 🎬: I'm making a complete course about Kubernetes Networking, covering rest of the topics, like ► how pods communicate with each other on the same node and across hundreds of servers? ► how does the outside world communicate with K8s cluster? ► how K8s cluster plugs into the underlying infrastructure network? ► Docker Container Networking ▬▬▬▬▬▬ T I M E S T A M P S 0:00 - Intro 0:46 - Pod - fundamental concept 1:05 - Problem with Container Port Mapping WITHOUT Pod 4:15 - Solution - Pod abstraction 6:28 - When do we need multiple containers in a pod?
