Updated: Feb 15

In containerized application development, Kubernetes has emerged as the de facto platform for orchestrating and managing containerized workloads. However, developing applications in Kubernetes environments can present challenges, particularly when it comes to streamlining the development workflow and ensuring consistency across different environments. To address these challenges, tools like Okteto have gained prominence, offering developers a seamless and efficient way to develop applications directly within Kubernetes clusters.

What is Okteto?

Okteto is a free tool that helps developers work on their applications in Kubernetes. It syncs code changes directly to a running pod in a local or remote Kubernetes cluster, so developers can test their changes instantly without the need to commit, build, and push container images. You can use your favorite tools and continue working in your usual environment.

Okteto works with any Kubernetes cluster, whether it's a local one like Minikube or one hosted in the cloud by providers like AWS, GCP, or Azure. To get started, developers need to install Okteto's CLI and configure their environment using the okteto init command. Then, they can run okteto up to start syncing their code.


Q&A on Okteto: A Tool to Develop Applications in Kubernetes

Question 1: What's Okteto? How does it help to develop applications in Kubernetes?

Okteto is an open-source tool that facilitates the creation of development environments within Kubernetes. It allows developers to launch development environments directly in Kubernetes clusters. With Okteto, developers can write their code locally using their preferred tools.

How does Okteto help to develop applications in Kubernetes?

Okteto simplifies the development process in Kubernetes by seamlessly synchronizing code changes from a local environment to the development environment running in Kubernetes. This means that as developers make changes to their code locally, Okteto automatically detects these changes and synchronizes them to the Kubernetes environment in real-time.

Developers can use their compilers and hot reloaders to instantly see the effects of their changes without the need for manual syncing or redeployment. Okteto operates exclusively on the client-side and is compatible with any Kubernetes cluster, whether it's a local cluster like Minikube or one hosted in the cloud by providers like AWS, GCP, or Azure.

Additionally, Okteto offers Okteto Cloud, a service that provides developers with free access to sandboxed Kubernetes namespaces. This cloud service integrates seamlessly with the open-source Okteto tool, allowing developers to develop applications in Kubernetes environments hosted either in the cloud or on-premises.

Question 2: How is Okteto different from other tools like Telepresence, Skaffold, or Draft?

Skaffold and Draft: 

These tools are developed to automate various repetitive tasks encountered during the process of building images and redeploying containers. They streamline these processes, aiming to make development workflows more efficient and less time-consuming.

Skaffold and Draft provide features such as

  1. Automated building

  2. Tagging, and pushing of container images to registries

  3. Deployment to Kubernetes clusters.

Their primary focus is on optimizing the development and deployment pipeline to enhance productivity.


Telepresence represents a significant advancement in development tooling by allowing developers to simulate their workstation's presence within the Kubernetes cluster at the network level. This enables seamless interaction between local development environments and services running in Kubernetes clusters.

With Telepresence, developers can effectively debug and test their applications in a real Kubernetes environment without the need for complex setup or additional infrastructure. It provides a convenient way to iterate on code changes and troubleshoot issues directly within the Kubernetes environment.


Okteto offers a unique approach to application development in Kubernetes by bringing the development environment directly into the cluster. Unlike other tools that focus on automating tasks or simulating network presence, Okteto eliminates the need for network abstraction layers by leveraging the cluster's resources directly. By doing so, it simplifies the development workflow and ensures consistency across different environments.

Developers can write code locally using their preferred tools, and Okteto automatically synchronizes code changes to the development environment running in Kubernetes. This seamless integration between local development and Kubernetes environments enables rapid iteration and testing of applications without the overhead of manual syncing or redeployment.

Key Differentiator: 

While Skaffold, Draft, and Telepresence offer valuable capabilities for Kubernetes development, Okteto stands out for its unique approach of bringing the development environment directly into the cluster.

By eliminating the need for network simulation and leveraging the cluster's resources, Okteto simplifies the development process and ensures consistency across environments.

Developers can benefit from a seamless workflow that allows them to write code locally and instantly see the effects of their changes within the Kubernetes environment. This approach reduces complexity, enhances productivity, and accelerates the development lifecycle.

Question 3: How does Okteto work?

Okteto operates by running a synchronization protocol locally and within the Kubernetes cluster using Syncthing, a file synchronization tool. The application code is synchronized from the local development environment to a pod running in the Kubernetes cluster. This pod is referred to as the "development environment."

Unlike traditional application pods, the development environment pod utilizes a different container image known as your development image. This image contains all the necessary tools pre-installed for development purposes.

Despite using a different container image, the development environment pod retains the configuration settings of the original pods, including identity, environment variables, and start command.

Developers have the flexibility to override nearly every configuration aspect of the pod by defining an Okteto manifest in YAML format. This allows for customization and fine-tuning of the development environment according to specific requirements.

Question 4: What other tools can integrate with Okteto?

Okteto is designed to seamlessly integrate with various development and deployment tools, providing flexibility and compatibility across different workflows.

Here are the tools that can integrate with Okteto:

  • IDE Compatibility: Okteto allows developers to write their code locally using their preferred Integrated Development Environment (IDE). This means that Okteto is compatible with any IDE, whether it's Visual Studio Code, IntelliJ IDEA, or any other popular development environment. Developers can continue using their familiar tools and workflows while leveraging the capabilities of Okteto for Kubernetes development.

  • Decoupled Deployment: One of the key design decisions behind Okteto is to decouple deployment from development. This means that developers can choose to deploy their applications using various deployment tools such as kubectl, Helm, serverless frameworks, or even Continuous Integration (CI) pipelines. Okteto enables developers to develop any component of their application independently of the deployment process.

  • Integration with Kubernetes Ecosystem: Since development environments in Okteto run within Kubernetes clusters, they naturally integrate with various Kubernetes ecosystem components. This includes service mesh frameworks like Istio or Linkerd, ingress controllers, storage classes, and security policies. By leveraging existing cluster configurations, developers can seamlessly interact with these components without the need to mock dependencies or simulate environments. This native integration simplifies development workflows and ensures consistency across different environments.
