When a Kubernetes pod is in a Pending state, it means that the pod has been accepted by the cluster, but it cannot be scheduled to run on any node. Several reasons could cause this, ranging from insufficient resources to…
To list all the containers running in a Kubernetes cluster, you would typically start by listing all Pods, as containers are encapsulated within Pods in Kubernetes. Each Pod can run one or more containers. Here’s how you can list all…
Kubernetes, or K8s, stands as a pivotal force in the contemporary landscape of container orchestration, offering a robust platform for deploying, scaling, and managing containerized applications. A critical aspect of Kubernetes’ functionality revolves around resource management, particularly in terms of…
Identifying the busiest pod in a Kubernetes cluster, in terms of resource usage (CPU and memory), involves a few steps. There isn’t a direct kubectl command that gives you this information outright, but you can use a combination of commands…
In Kubernetes, when configuring a Service to expose your applications, you’ll encounter three key port concepts: port, targetPort, and NodePort. Understanding the distinctions and relationships between these ports is crucial for effectively managing access to your applications running within Pods.…
In Kubernetes, when defining a Service to expose your application, the concept of targetPort plays a crucial role in routing incoming traffic to the correct destination within your Pods. What is targetPort? How does targetPort work? Example Usage Consider a…
Minikube is a tool that simplifies the process of running Kubernetes locally, making it easier for developers to develop and test Kubernetes applications. One of the key concepts in Minikube is the use of “drivers” to set up and manage…
In a Kubernetes environment, understanding the different types of IP addresses and how they are used is crucial for managing communication within and outside the cluster. understanding different types of IP addresses in Kubernetes To illustrate these concepts, let’s consider…
Kubernetes, the orchestration system for managing containerized applications, offers a variety of service types to ensure your applications are accessible and communicate efficiently. Each service type caters to specific use cases, balancing accessibility with resource allocation. Let’s delve into the…
Pods are foundational to building and running applications in Kubernetes. They provide the execution environment for containers, encapsulating application components, managing their lifecycle, and facilitating inter-component communication and resource sharing. A Pod encapsulates one or more containers, storage resources, a…
