Learn how to deploy an Oracle Database 23ai (23.8.0.25) on your MacBook with Kubernetes using podman and minikube| Ron Ekins' - Oracle Technology, DevOps and Kubernetes Blog
A HorizontalPodAutoscaler (HPA for short) automatically updates a workload resource (such as a Deployment or StatefulSet), with the aim of automatically scaling the workload to match demand. Horizontal scaling means that the response to increased load is to deploy more Pods. This is different from vertical scaling, which for Kubernetes would mean assigning more resources (for example: memory or CPU) to the Pods that are already running for the workload.| 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
The difference between stateful and stateless applications is that stateful applications save past and present information while stateless applications don’t.| www.redhat.com
If you plan to run stateful applications in your Kubernetes cluster, you quickly run into the question of where to store this state. A database is often the best solution, though writing to disk is sometimes the only — or at least easier, option.| Stonegarden
A container image represents binary data that encapsulates an application and all its software dependencies. Container images are executable software bundles that can run standalone and that make very well defined assumptions about their runtime environment. You typically create a container image of your application and push it to a registry before referring to it in a Pod. This page provides an outline of the container image concept. Note:If you are looking for the container images for a Kub...| Kubernetes

Node-pressure eviction is the process by which the kubelet proactively terminates pods to reclaim resources on nodes. FEATURE STATE: Kubernetes v1.31 [beta] (enabled by default: true) Note:The split image filesystem feature, which enables support for the containerfs filesystem, adds several new eviction signals, thresholds and metrics. To use containerfs, the Kubernetes release v1.32 requires the KubeletSeparateDiskGC feature gate to be enabled. Currently, only CRI-O (v1.29 or higher) offers ...| Kubernetes

The store-gateway is the Cortex service responsible to query series from blocks. The store-gateway is required when running the Cortex blocks storage. The store-gateway is semi-stateful. How it works The store-gateway needs to have an almost up-to-date view over the storage bucket, in order to discover blocks belonging to their shard. The store-gateway can keep the bucket view updated in to two different ways: Periodically scanning the bucket (default) Periodically downloading the bucket inde...| Cortex
Production-Grade Container Orchestration| Kubernetes
Dealing with storage is a core challenge when running complex applications on Kubernetes. While many applications operate just fine using a cloud database or blob storage, some applications have performance or design requirements requiring local storage. Note: For performance benchmarks see [Benchmarking AWS CSI Drivers](<{{ relref “/post/kubernetes/benchmarking-aws-csi-drivers” }}). When this is the case, developers and cluster operators rely on Container Storage Interface (CSI) implemen...| sookocheff.com
Our latest report examines more than 2.4 billion containers run by tens of thousands of Datadog customers to understand the state of the container ecosystem.| Datadog
This page describes running Kubernetes across multiple zones. Background Kubernetes is designed so that a single Kubernetes cluster can run across multiple failure zones, typically where these zones fit within a logical grouping called a region. Major cloud providers define a region as a set of failure zones (also called availability zones) that provide a consistent set of features: within a region, each zone offers the same APIs and services.| Kubernetes
This page shows how to run a replicated stateful application using a StatefulSet. This application is a replicated MySQL database. The example topology has a single primary server and multiple replicas, using asynchronous row-based replication. Note:This is not a production configuration. MySQL settings remain on insecure defaults to keep the focus on general patterns for running stateful applications in Kubernetes. Before you begin You need to have a Kubernetes cluster, and the kubectl comma...| Kubernetes
Kubernetes reserves all labels, annotations and taints in the kubernetes.io and k8s.io namespaces. This document serves both as a reference to the values and as a coordination point for assigning values. Labels, annotations and taints used on API objects apf.kubernetes.io/autoupdate-spec Type: Annotation Example: apf.kubernetes.io/autoupdate-spec: "true" Used on: FlowSchema and PriorityLevelConfiguration Objects If this annotation is set to true on a FlowSchema or PriorityLevelConfiguration, ...| Kubernetes
You can visualize and manage Kubernetes objects with more tools than kubectl and the dashboard. A common set of labels allows tools to work interoperably, describing objects in a common manner that all tools can understand. In addition to supporting tooling, the recommended labels describe applications in a way that can be queried. The metadata is organized around the concept of an application. Kubernetes is not a platform as a service (PaaS) and doesn't have or enforce a formal notion of an ...| Kubernetes
With contributions from Adriana Villela (Lightstep from ServiceNow). For the OpenTelemetry (OTel) End User Working Group’s fourth End User Q&A session of 2023, we spoke with Jacob Aronoff, Staff Software Engineer at Lightstep from ServiceNow and an OpenTelemetry Operator Maintainer. Read on if you are interested in learning how a vendor is using OTel in-house! This series of interviews is a monthly casual discussion with a team that’s using OpenTelemetry in production.

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
