API Library for Visual Studio Code Kubernetes Tools

A NPM package providing documentation and helpers for using the Kubernetes extension for Visual Studio Code in your own VS Code extensions. You can use this to:

  • Add nodes to the Cluster Explorer tree
  • Add custom commands to the Cluster Explorer
  • Customise the appearance of the Cluster Explorer
  • Invoke kubectl features in a way that's consistent with the core extension
  • Integrate additional clouds or other Kubernetes environments into the extension

The package includes TypeScript type declarations and JSDoc comments. For usage information and samples, see https://aka.ms/vscodekubeapi.

Example usage

// Using TypeScript for sample purposes but it all works in JavaScript too!

import * as vscode from 'vscode';
import * as k8s from 'vscode-kubernetes-tools-api';

export function activate(context: vscode.ExtensionContext) {
    const disposable = vscode.commands.registerCommand('k8stop.top', showResourceUsage);
    context.subscriptions.push(disposable);
}

async function showResourceUsage(target?: any): Promise<void> {
    // Standard pattern for accessing the APIs
    const explorer = await k8s.extension.clusterExplorer.v1_1;
    if (!explorer.available) {
        vscode.window.showErrorMessage(`Command not available: ${explorer.reason}`);
        return;
    }
    const kubectl = await k8s.extension.kubectl.v1;
    if (!kubectl.available) {
        vscode.window.showErrorMessage(`kubectl not available: ${kubectl.reason}`);
        return;
    }

    // Example of using the Cluster Explorer API to figure out what was clicked
    const node = explorer.api.resolveCommandTarget(target);
    if (node && node.nodeType === 'resource' && node.resourceKind.manifestKind === 'Node') {

        // Example of using the kubectl API to invoke a command
        const topResult = await kubectl.api.invokeCommand(`top node ${node.name}`);

        if (!topResult || topResult.code !== 0) {
            vscode.window.showErrorMessage(`Can't get resource usage: ${topResult ? topResult.stderr : 'unable to run kubectl'}`);
            return;
        }
        const topCommandOutput = topResult.stdout;
        // show topCommandOutput as required;
    }
}
