Kubernetes namespaces create isolated environments by providing a virtual subdivision of the cluster, allowing resources to be grouped and managed separately. When you create a namespace, it generates a unique scope for resource names under its umbrella. This ensures that resources belonging to differen...
Kube-controller-manager is a control plane process that runs on the master node of a Kubernetes cluster. It is responsible for running various controllers that handle routine tasks in the cluster, such as node management, endpoints, and namespace management. It is also responsible for running the...
What is a StatefulSet in Kubernetes? A StatefulSet is a controller that helps you deploy and scale groups of Kubernetes pods. When using Kubernetes, most of the time you don’t care how your pods are scheduled, but sometimes you care that pods are deployed in order, that they have a pers...
Clients can communicate with the Kubernetes system thanks to the exposed Kubernetes API. 3. Etcd The state of the Kubernetes cluster, including the desired state of the applications and the cluster’s configuration, is stored in etcd, a distributed key-value store. 4. Controller Manager The cont...
A Kubernetes service is a logical abstraction for a deployed group of pods in a cluster (which all perform the same function).
Kubernetes ensures that an application has sufficient resources, operates reliably, and maintainshigh availabilitythroughout its lifecycle. The location of the application within the cluster is not a primary concern. DaemonSets address Kubernetes' scheduling limitations by guaranteeing the deployment of a ...
Kubernetes is a tool for elegant container orchestration of complex business requirements, such as highly available microservices, and is one of the enabling technologies of the 12-factor application. Initially developed by Google, Kubernetes is currently managed by the Cloud Native Computing Foundation....
Deploying a stateful data service such as RabbitMQ to Kubernetes without using the Kubernetes Operator is a bit like assembling a jigsaw puzzle. There are multiple pieces involved: A Kubernetes namespace A stateful set for RabbitMQ cluter nodes Ensuring durable storage is used by node data directo...

Critical asset protection is extended to support additional use cases for containers.Users can now create custom rules that mark assets managed by Kubernetes (workloads, containers, etc.) as critical based on the asset Kubernetes namespace and/or the asset Kubernetes label....
