Pods are the smallest deployable units of computing that you can create and manage in Kubernetes. A Pod (as in a pod of whales or pea pod) is a group of one or more containers, with shared storage and network resources, and a specification for how to run the containers. A Pod's contents are always co-located and co-scheduled, and run in a shared context. A Pod models an application-specific "logical host": it contains one or more application containers which are relatively tightly coupled.| Kubernetes
Make your HTTP (or HTTPS) network service available using a protocol-aware configuration mechanism, that understands web concepts like URIs, hostnames, paths, and more. The Ingress concept lets you map traffic to different backends based on rules you define via the Kubernetes API.| Kubernetes
The Kubernetes model for connecting containers Now that you have a continuously running, replicated application you can expose it on a network. Kubernetes assumes that pods can communicate with other pods, regardless of which host they land on. Kubernetes gives every pod its own cluster-private IP address, so you do not need to explicitly create links between pods or map container ports to host ports. This means that containers within a Pod can all reach each other's ports on localhost, and a...| Kubernetes
Kubernetes (version 1.3 through to the latest 1.31, and likely onwards) lets you use Container Network Interface (CNI) plugins for cluster networking. You must use a CNI plugin that is compatible with your cluster and that suits your needs. Different plugins are available (both open- and closed- source) in the wider Kubernetes ecosystem. A CNI plugin is required to implement the Kubernetes network model. You must use a CNI plugin that is compatible with the v0.| Kubernetes

Using kubeadm, you can create a minimum viable Kubernetes cluster that conforms to best practices. In fact, you can use kubeadm to set up a cluster that will pass the Kubernetes Conformance tests. kubeadm also supports other cluster lifecycle functions, such as bootstrap tokens and cluster upgrades. The kubeadm tool is good if you need: A simple way for you to try out Kubernetes, possibly for the first time. A way for existing users to automate setting up a cluster and test their application.| Kubernetes
Virtual networking has been one of the hottest areas of research and development in recent years. Kubernetes alone has, at the time of writing, 20 different networking plugins, some of which can be combined to build even more plugins. However, if we dig a bit deeper, most of these plugins and solutions are built out of two very simple constructs: a virtual switch - anything from a linux bridge through VPP and IOVisor to OVS ACL/NAT - most commonly implemented as iptables, with anything from n...| networkop
In this post, we discuss the risks of the AWS Instance Metadata service in AWS Elastic Kubernetes Service (EKS) clusters. In particular, we demonstrate that compromising a pod in the cluster can have disastrous consequences on resources in the AWS account if access to the Instance Metadata service is not explicitly blocked. Introduction For the purposes of this post, we’ll use an EKS cluster running Kubernetes v1.17.9 and created with eksctl. We could also have created the cluster using Ter...| Christophe Tafani-Dereeper
I want to avoid using the expensive Google Network Load Balancer and instead do the load balancing in-cluster using akrobateo, which acts as a LoadBalancer controller.| maelvls.dev
In my previous post, I described how migrating to Kubernetes involves transitioning an organization’s infrastructure from a legacy service platform (LeSP) to a Kubernetes service platform (KuSP). In this post, I want to go into more details on why this migration is hard and what you can do to reduce the pain associated with this transition.| Benjamin Yolken
Note: Dockershim has been removed from the Kubernetes project as of release 1.24. Read the Dockershim Removal FAQ for further details. You need to install a container runtime into each node in the cluster so that Pods can run there. This page outlines what is involved and describes related tasks for setting up nodes. Kubernetes 1.33 requires that you use a runtime that conforms with the Container Runtime Interface (CRI).| Kubernetes
A DaemonSet defines Pods that provide node-local facilities. These might be fundamental to the operation of your cluster, such as a networking helper tool, or be part of an add-on.| Kubernetes
