In Kubernetes, you cannot directly “stop” and then “start” a pod in the same way you might stop and start a virtual machine. Pods in Kubernetes are designed to be ephemeral and stateless entities, managed by higher-level controllers like Deployments,…
You can effectively restart a pod in Kubernetes, but not in the same way you might restart a service on a traditional VM using a command like systemctl restart. Since Kubernetes manages pods based on desired states, you have to…
Deploying PostgreSQL in a Kubernetes (K8s) environment involves several steps, including creating a Deployment or StatefulSet for PostgreSQL, setting up persistent storage to ensure data durability, and configuring network access. Below is a detailed guide to get you started. Prerequisites…
In Kubernetes, when you deploy workloads using container images, the images are typically pulled from a container image registry specified in the deployment configuration. To check which image registry is being used by your containers in Kubernetes, you need to…
Welcome to the world of Kubernetes, where managing applications becomes a breeze! If you’re new here, you might wonder what all the buzz is about. Think of Kubernetes like a magical tool that helps keep your app’s pieces running smoothly,…
To create a PostgreSQL pod in Kubernetes, you’ll need to define a pod configuration in a YAML file that specifies the PostgreSQL image and any necessary configurations such as environment variables for setting up the database. Create PostgreSQL pod in…
In Kubernetes, both Deployments and ReplicaSets are pivotal concepts that help manage the lifecycle of your applications by ensuring that a specified number of pod replicas are running at any given time. Understanding the differences between a Deployment and a…
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…
