Why You Should Use Kubernetes for Your Development Environments

Through a service, any pod can be added or removed without the fear that basic network information would change in any way. If you need to scale your app, you can only do so by adding or removing pods. A Scheduler watches for new requests coming from the API Server and assigns them to healthy nodes. It ranks the quality of the nodes and deploys pods to the best-suited node. If there are no suitable nodes, the pods are put in a pending state until such a node appears. Much as a conductor would, Kubernetes coordinates lots of microservices that together form a useful application.

It brings its own concepts, best practices, and potential incompatibilities. Although individual containers remain the same, you have an extra layer handling inbound traffic, networking between services, and peripheral concerns such as configuration and storage. Kubernetes has become one of the most popular ways to run containerized workloads in production.


Managing the lifecycle of containers with Kubernetes alongside a DevOps approach helps to align software development and IT operations to support a CI/CD pipeline. At its core, DevOps relies on automating routine operational tasks and standardizing environments across an app’s lifecycle. Containers support a unified environment for development, delivery, and automation, and make it easier to move apps between development, testing, and production environments.

  • Instead of managing containers directly, users define and interact with instances composed of various primitives provided by the Kubernetes object model.
  • By providing a simple HTTP/JSON API, the interface for setting or retrieving values is very straight forward.
  • Kubernetes is built to be used anywhere, allowing you to run your applications across on-site deployments and public clouds; as well as hybrid deployments in between.
  • Production apps span multiple containers, and those containers must be deployed across multiple server hosts.
  • Therefore, as a best Kubernetes practice, you should use Alpine Images 10 times smaller than the base images.

VMs make better use of resources and are much easier and more cost-effective to scale than traditional infrastructure. And, they’re disposable — when you no longer need to run the application, you take down the VM. To understand Kubernetes better, a look at the previous methods for deployment of enterprise applications is necessary. Traditionally, business organizations used physical servers to install and run applications, a period known as the traditional deployment era.

Narrowing the Gap With Operations

This of course depends heavily on the type of work environment you use. Local environments need to be set up individually by every developer because they are only running on local computers, which prevents a central setup. This is why you should provide detailed instructions on how to start the local environment.

What is development in Kubernetes

Kubernetes can fit containers onto your nodes to make the best use of your resources. A good understanding of container fundamentals will help you understand what Kubernetes adds and how it works. There are now several good options for deploying a local Kubernetes cluster on a development workstation. Using this kind of solution means you don’t need to wait for test deployments to rollout to remote infrastructure.


Static Pods are managed directly by the kubelet daemon on a specific node, without the API serverobserving them. Whereas most Pods are managed by the control plane , for static Pods, the kubelet directly supervises each static Pod . All containers in the Pod can access the shared volumes, allowing those containers to share data.

Kubernetes lets you define complex containerized applications and run them at scale across a cluster of servers. Kubernetes works by managing a cluster of compute instances and scheduling containers to run on the cluster based on the available compute resources and the resource requirements of each container. Containers are run in logical groupings called pods and you can run and scale one or many containers together as a pod. Containerization technology is rapidly changing the patterns of IT architecture of application development, and Kubernetes remains its flag-bearer. As per Forrester’s 2020 Container Adoption Survey, about 65% of the respondent enterprises have used or planned to use container orchestration tools.

Required skills for Kubernetes developers (6-8 bullet points)

By changing the system, I was playing a cat and mouse game with kubernetes’ attempts to auto-fix the error. Adding GUI-based operations like finding the exact point causing latency OR showing the POD consuming the highest CPU/RAM would be of great help. Flexibility gives birth to complexity & therefore designing an application on K8s is also complex.

What is development in Kubernetes

You’ll rarely create individual Pods directly in Kubernetes—even singleton Pods. This is because Pods are designed as relatively ephemeral, disposable entities. When a Pod gets created , the new Pod is scheduled to run on a Node in your cluster.

In production, most of the concerns above are solved with Terraform or CloudFormation. But when I wanted to simply create a small cluster to try out new things, using the CLI or the GUI often took a while to provision, only to realize that I missed a setting or IAM roles later in the process. Does not provide nor adopt any comprehensive machine configuration, maintenance, management, or self-healing systems. Continuous Integration, Delivery, and Deployment (CI/CD) workflows are determined by organization cultures and preferences as well as technical requirements. K8s as an abbreviation results from counting the eight letters between the “K” and the “s”.

Instead, one or more tightly coupled containers are encapsulated in an object called a pod. Mykyta Protsenko discusses the trade-offs that companies face during the process of shifting left, how to ease cognitive load for the developers, and how to keep up with the evolving practices. kubernetes development In this podcast Shane Hastie, spoke to Katherine Jarmul of Thoughtworks about the dangers of techno-solutionism, challenges in ethical application of technology and her book Practical Data Privacy. With Docker Container Management you can manage complex tasks with few resources.

Kubelet monitors the state of a pod, and if not in the desired state, the pod re-deploys to the same node. Node status is relayed every few seconds via heartbeat messages to the primary. Once the primary detects a node failure, the Replication Controller observes this state change and launches pods on other healthy nodes. Once you scale this to a production environment and multiple applications, it’s clear that you need multiple, colocated containers working together to deliver the individual services.
