Why You Should Use Kubernetes for Your Development Environments

You can also swap deployments from remote clusters as long as they can be accessed via kubectl. This can be very useful for the debugging and tracing of bugs on test systems, for example. Caution is advised, however, as every deployment traffic is directed to the local laptop after the swap. That means that this approach is only really suited to test systems and should be avoided at all costs in the case of most production systems. Another solution for local Kubernetes development ist Telepresence. It is a so-called sandbox project by the CNCF, the Cloud Native Computing Foundation.

What is development in Kubernetes

The following command will spin your local development container for spacecrafts up. Please note you need to adjust the name of the container, run kubectl get pods to get the right identifier. A good understanding of container fundamentals will help you understand kubernetes development 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.

What is a Kubernetes Development Environment (KDE)?

However, Docker-produced images will continue to work in your cluster with all runtimes, including CRI-O. Unikube makes K8s also viable for smaller applications as ist streamlines your DevOps with fast development, zero hiccups and zero downtime. One command and your devs have a perfectly configured local cluster running. Unikube automates rolling out Kubernetes environments to your team, installing all necessary tools and dependencies without any Kubernetes knowledge needed. These API resources represent objects that are not part of the standard Kubernetes product.

  • Try Kubernetes Learn to build and deploy your application in a real environment.
  • Developers can make changes to the source code, files, environment variables and let them run in the context of all other attached services.
  • Coming from Symfony there has been a lot of progress, like the Api-Platform project shipping directly dockerized using Docker Compose and ready for deployment via Kubernetes and Helm.
  • We wanted a CLI that could be distributed as a single binary to our developers, so we created one called Devgun.

In this environment, you can run multiple programs on multiple servers. Following this example, Kubernetes acts as a lunchbox by bundling clusters of applications, while isolating various software components. Kubernetes is portable in the same way a lunchbox is, since you can run it anywhere — on Ubuntu, the cloud, or on-premises. Let’s explore Kubernetes in simple language, identify Kubernetes advantages, and explain how to use Kubernetes for development environments. Even as VMs improved some aspects of computing, virtualization is hardware-centric, meaning that scaling operations will, at some point, require you to buy new hardware. If you experience rapid growth, or want to deploy software rapidly using Continuous Integration and Continuous Delivery , this can quickly become expensive.


Bottomline is cloud developers need to work with cloud-based services and tools, which can be difficult to use in a local development environment. Cloud developers need to be able to quickly iterate and deploy code changes, which can be a problem when it comes to managing multiple microservices that comprise today’s complex cloud applications. Whether it is a single cluster or multi-cluster setup, you need adequate skills for installing and properly configuring nodes, pods, containers, and your application deployment.

What is development in Kubernetes

An application might have identity requirements or numbering requirements. For example, you might be required to run exactly three instances of the application and to name the instances 0, 1, and 2. Stateful sets are most useful for applications that require independent storage, such as databases and zookeeper clusters. While individual pods represent a scalable unit in Kubernetes, aserviceprovides a means of grouping together a set of pods to create a complete, stable application that can complete tasks such as load balancing. A service is also more permanent than a pod because the service remains available from the same IP address until you delete it. When the service is in use, it is requested by name and the OpenShift Container Platform cluster resolves that name into the IP addresses and ports where you can reach the pods that compose the service.

Developing applications on Kubernetes

Ultimately, with the help of Okteto, accelerated developer velocity by 50%. In this story, we introduced the infinite loop of pain and suffering every developer enters trying to develop locally on Kubernetes. Detect changes in your source code and automatically build/push/deploy. Skaffold detects the changes in your source code as they happen , kicking the pipeline to build, tag, push and deploy your application automatically.

When a service is defined, one can define the label selectors that will be used by the service router/load balancer to select the pod instances that the traffic will be routed to. This capability to dynamically control how services utilize implementing resources provides a loose coupling within the infrastructure. File systems in the Kubernetes container provide ephemeral storage, by default.

Kubernetes for Microservices Management

CloudPlex automatically creates and configures the Service Accounts, Roles, and Role Bindings. CloudPlex can help managers and development teams to make the transition to Kubernetes smooth. When it comes to CI tools such as Jenkins, CircleCI, Bitbucket, etc., you just have to integrate webhook in your CI pipeline—a copy-paste operation.

If you are looking for that kind of convenience and a team oriented workflow, check out Unikube, which combines all needed tools for effortless local kubernetes development. Then we initialized gefyra in the cluster and executed our image with gefyra run, to make it part of the cluster. You need to change it appropriately to the name of the pod that’s running in your cluster, if you’re following these steps. We start the container with Hurricanes serve command with the autoreload flag and two flags for debugging, which we need later on.

WATCH! Developer productivity on Kubernetes with OpenShift

To successfully work with Kubernetes, you need a team of developers, operation managers, and admins, each of which must go into the project properly trained and ready to hit the ground running. Each Docker composition deployment was so resource-heavy that collectively they were killing laptops like a Halloween horror movie. Unfortunately, deploying a LocalStack to mimic AWS didn’t help much. At some point, it became impossible for the development team to run more than a couple of microservices simultaneously. But maybe the biggest problem with local developments is that they don’t work with Kubernetes.

You can use Draft to create both the Dockerfile and the Kubernetes manifests for an existing application. In this article, we are reviewing three such development tools that are helping developers to work with local Kubernetes clusters. By automating the local development workflow, we can significantly reduce the deployment and testing phases and provide a quick feedback loop which is always crucial for developer productivity. Software architects have worked at breaking up large-scale applications into broadly reusable components for decades.

Benefits of Using Kubernetes in Dev Environments

This book provides a strong technical foundation in modern software development and operations. Practical examples show you how to apply the concepts and teach you the full potential of Kubernetes. For “production” base images one of the maintainers will run make -C images/base push which cross-compiles for all architectures and pushes to the registry. This takes you to a step-by-step guide on setting up Telepresence, connecting to a development cluster, and creating intercepts. When you ultimately run your containers in OpenShift Container Platform, you use theCRI-Ocontainer engine. CRI-O runs on every worker and control plane machine in an OpenShift Container Platform cluster, but CRI-O is not yet supported as a standalone runtime outside of OpenShift Container Platform.
