What is Pod Lifecycle?

Basics of Kubernetes

Think of Kubernetes as the conductor of an orchestra; however, instead of musicians, it is in charge of orchestrating containers, which are executable packages that are standalone, lightweight, and carry all the necessary components for an application to execute. These containers can be easily set up in a variety of settings, including the cloud and your laptop....

What is Kubernetes deployment and pod?

Kubernetes Deployment: Think about deployments as blueprints for your application’s final state. They specify how many instances of your application should be running, what resources each instance requires, and how to deal with updates and rollbacks....

Why Kubernetes Deployments and Pod required?

The demand for scalability, dependability, and efficiency in application management gives rise to the necessity for Kubernetes deployments and pods. Because Kubernetes abstracts away the underlying infrastructure concerns, developers can concentrate on developing and deploying their apps rather than worrying about the specifics of where and how they run. Basically, all the backend processes are taken care of by Deployments and Pods itself....

What is Pod Lifecycle?

Pods have a predetermined lifecycle. They begin in the Pending phase, proceed through the Running phase (assuming that at least one of their primary containers starts successfully), and then proceed through the Succeeded or Failed phases (depending on whether any of the pod’s containers ended successfully or not). The kubelet can restart containers to address various errors while a pod is operating....

What is Scalability ?

By allowing you to scale over several clusters, Kubernetes scaling enables you to allocate workloads across various availability zones or regions. This guarantees high availability even in the case of infrastructure failures in a particular region, offers geographical redundancy, and enhances performance for users in many places....

What is K8s Rolling Updates and Rollback ?

Kubernetes Rolling Updates gradually replace older application instances with newer ones to ensure continuous availability. Rollbacks allow reverting to a previous version in case of deployment issues, maintaining system reliability. In simpler words, Think of Kubernetes Rolling Updates like renovating a house while still living in it. Instead of shutting down the entire house, you update one room at a time, ensuring you always have a place to stay. Similarly, Rolling Updates in Kubernetes let you update parts of your application without taking it offline, ensuring continuous service for your users. Now, imagine you painted a room the wrong color or installed a faulty appliance during the renovation. Rollbacks in Kubernetes are like having a magical undo button. If something goes wrong with the update, you can quickly go back to the previous version, keeping your application running smoothly without any hiccups....

Deployment of one Sample Application in K8s Cluster

Let’s deploy a ArgoCD application, It keeps an eye on active programs and contrasts their present, live state with the intended target state (as defined in the Git repository). An application that has been deployed and whose live state differs from the intended state is said to be out of sync....

Real Time Use Cases, Live Demonstration with Snapshots and Best Practices

Step 1: Let’s take an example of vault installation, which is nothing but an extra security layer for applications. Many big MNCs uses this in real time and this is the best and easy to use security layer on top of any application....
