vs-kubernetes README

vs-kubernetes provides a Visual Studio Code extension for interacting with Kubernetes clusters.

Configuring

Setting up your environment

This extension assumes that you have a Dockerfile in the root directory of your project.

It also assumes that you have the following binaries on your PATH:

  • kubectl
  • docker
  • git
  • draft (optional)

If you don't have those on your PATH then the extension will fail in unexpected ways.

For setting up kubectl you have a couple of additional options:

  • If kubectl is not on your PATH then you can tell the extension its location using the vs-kubernetes.kubectl-path workspace setting. This should be the full file name and path of the kubectl binary.
  • If you are using the extension to work with an Azure Container Service then you can install and configure kubectl using the Kubernetes Configure from ACS command.

For setting up draft you can also do this via configuration.

Setting up the image repository path

If you want to use the Kubernetes Run and Kubernetes Debug features then you need to have correctly set the image and repository for your images. You can do this via preferences in VS-Code:

File > Preferences

And then add:

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

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

Features

vs-kubernetes supports a number of commands for interacting with Kubernetes, they are accessible via the command menu (ctrl-shift-p)

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 - Get logs for a pod in an output window.

Commands while viewing a Kubernetes file

  • Kubernetes Explain - Use the kubectl explain ... tool to annotate Kubernetes API objects
  • Kubernetes Create - Create an object using the current document
  • Kubernetes Delete - Delete an object contained in the current document.
  • Kubernetes Apply - Apply changes to an object contained in the current document.
  • Kubernetes Expose - Expose the object in the current document as a service.

Commands for application directories

  • Kubernetes Run - Run the current application as a Kubernetes Deployment
  • Kubernetes Terminal - Open an interactive terminal session in a pod of the Kubernetes Deployment
  • Kubernetes Exec - Run a command in a pod of the Kubernetes Deployment
  • Kubernetes Debug - Run the current application as a Kubernetes Deployment and attach a debugging session to it (currently works only for Node.js deployments)
  • Kubernetes Remove Debug - Remove the deployment and/or service created for a Kubernetes Debug session

Configuration commands

  • Kubernetes Configure from ACS - Install and configure the Kubernetes command line tool (kubectl) from an Azure Container Service

Draft support

Draft is a tool to simplify the process of developing a new Kubernetes application, by creating the necessary deployment components and by keeping code in the cluster in sync with the code on your computer.

  • Kubernetes Draft: Create - Set up Draft in the current folder (prerequisite for syncing using Draft)
  • Kubernetes Draft: Up - Runs Draft to watch the current folder and keep the cluster in sync with it

NOTE: Draft itself is in 'draft' form and is not yet stable. So the extension support for Draft is strictly experimental - assumptions may break, and commands and behavior may change!

Extension Settings

  • vs-kubernetes - Parent for Kubernetes-related extension settings
    • vs-kubernetes.namespace - The namespace to use for all commands
    • vs-kubernetes.kubectl-path - File path to the kubectl binary. Note this is the binary file itself, not just the directory containing the file. On Windows, this must contain the .exe extension.
    • vs-kubernetes.draft-path - File path to the draft binary. Note this is the binary file itself, not just the directory containing the file. On Windows, this must contain the .exe extension.
  • vsdocker.imageUser - Image prefix for docker images e.g. 'docker.io/brendanburns'

Known Issues

Nothing known (plenty unknown ;)
