Learn how to set up a Kubernetes sidecar deployment using CircleCI.| CircleCI
Editors: Agustina Barbetta, Aakanksha Bhende, Udi Hofesh, Ryota Sawada, Sneha Yadav Similar to previous releases, the release of Kubernetes v1.33 introduces new stable, beta, and alpha features. The consistent delivery of high-quality releases underscores the strength of our development cycle and the vibrant support from our community. This release consists of 64 enhancements. Of those enhancements, 18 have graduated to Stable, 20 are entering Beta, 24 have entered Alpha, and 2 are deprecated...| Kubernetes
As cloud-native architectures continue to evolve, Kubernetes has become the go-to platform for deploying complex, distributed systems. One of the most powerful yet nuanced design patterns in this ecosystem is the sidecar pattern—a technique that allows developers to extend application functionality without diving deep into source code. The origins of the sidecar pattern Think of a sidecar like a trusty companion motorcycle attachment. Historically, IT infrastructures have always used auxili...| Kubernetes
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
Kubernetes volumes provide a way for containers in a pod to access and share data via the filesystem. There are different kinds of volume that you can use for different purposes, such as: populating a configuration file based on a ConfigMap or a Secret providing some temporary scratch space for a pod sharing a filesystem between two different containers in the same pod sharing a filesystem between two different pods (even if those Pods run on different nodes) durably storing data so that it s...| Kubernetes

This page provides an overview of init containers: specialized containers that run before app containers in a Pod. Init containers can contain utilities or setup scripts not present in an app image. You can specify init containers in the Pod specification alongside the containers array (which describes app containers). In Kubernetes, a sidecar container is a container that starts before the main application container and continues to run. This document is about init containers: containers tha...| Kubernetes
Production-Grade Container Orchestration| Kubernetes
This page describes the lifecycle of a Pod. Pods follow a defined lifecycle, starting in the Pending phase, moving through Running if at least one of its primary containers starts OK, and then through either the Succeeded or Failed phases depending on whether any container in the Pod terminated in failure. Like individual application containers, Pods are considered to be relatively ephemeral (rather than durable) entities. Pods are created, assigned a unique ID (UID), and scheduled to run on ...| Kubernetes
This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components. See feature stages for an explanation of the stages for a feature. Overview Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component. Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that comp...| Kubernetes
