Visual Studio Code Kubernetes Tools

The extension for developers building applications to run in Kubernetes clusters and for DevOps staff troubleshooting Kubernetes applications.

Works with any Kubernetes anywhere (Azure, Minikube, AWS, GCP and more!).

Features include:

• View your clusters in an explorer tree view, and drill into workloads, services, pods and nodes.
• Browse Helm repos and install charts into your Kubernetes cluster.
• Intellisense for Kubernetes resources and Helm charts and templates.
• Edit Kubernetes resource manifests and apply them to your cluster.
• Build and run containers in your cluster from Dockerfiles in your project.
• View diffs of a resource's current state against the resource manifest in your Git repo
• Easily check out the Git commit corresponding to a deployed application.
• Run commands or start a shell within your application's pods.
• Get or follow logs and events from your clusters.
• Forward local ports to your application's pods.
• Create Helm charts using scaffolding and snippets.
• Watch resources in the cluster explorer and get live updates as they change

Getting started with the extension

Install

Open this extension in the Visual Studio Marketplace

Dependencies

The Kubernetes extension may need to invoke the following command line tools, depending on which features you use. You will need kubectl at minimum, and docker or buildah if you plan to use the extension to build applications rather than only browse.

• kubectl
• docker or buildah
• helm

Optional tools:

• az (Azure CLI - only if using the extension to create or register Azure clusters)
• minikube (only if you want to use it)
• git (only if using the 'sync working copy to repository' feature)
• buildah (can be used as an alternative container image build tool)

We recommend you install these binaries on your system PATH before using the extension. If these binaries aren't on your system PATH, then some commands may not work. If the extension needs one of the core Kubernetes tools and it's missing, it will offer to install it for you.

Configuration settings for building and running applications

If you want to use the Kubernetes: Run and Kubernetes: Debug features then you need to configure a user and repository for your container images. This is required because these commands need pushing an image of your application for your cluster to run it. To do this, add the following to your VS Code preferences (File > Preferences):

{
  "vsdocker.imageUser": "<your-image-prefix-here>",
}

where <your-image-prefix-here> is something like docker.io/brendanburns.

That's it! You're good to go.

Working with kubeconfigs

By default, the extension uses the active kubeconfig file -- that is, the file to which the KUBECONFIG environment variable points, or the default kubeconfig if no KUBECONFIG environment variable exists. You can override this using the vs-kubernetes.kubeconfig setting in your user or workspace settings.

If you want to swap between multiple kubeconfig files, you can list them in the vs-kubernetes.knownKubeconfigs configuration setting and switch between them using the Set Kubeconfig command.

If you want to skip TLS verification for a particular cluster, you can edit your ~/.kube/config and set the insecure-skip-tls-verify: true flag under the proper cluster:

- cluster:
    insecure-skip-tls-verify: true
    server: https://my-insecure-cluster:443
    name: my-insecure-cluster:443

Commands and features

vs-kubernetes-tools supports a number of commands for interacting with Kubernetes; these are accessible via the command menu (Ctrl+Shift+P) and may be bound to keys in the normal way.

Kubernetes

General commands

• Kubernetes: Load - Load a resource from the Kubernetes API and create a new editor window.
• Kubernetes: Get - Get the status for a specific resource.
• Kubernetes: Logs - Open a view with a set of options to display/follow logs.
