Google Home Action to communicate with Kubernetes

This project allows you to connect your Google Home to your Kubernetes cluster and control it via voice commands. It's not a public Google Home Action, since you have to configure Kubernetes access manually for your cluster.

This repository contains Dialogflow configuration as well, which can be imported into existing project. It can be customized later.

Example conversation:

[you] Hey Google, talk to Kubernetes Manager

[assistant] Welcome to Kubernetes Manager. How can I help you?

[you] Scale statefulset "redis"

[assistant] Got it. Currently, there are 3 replicas of the "redis" statefulset. To how many replicas do you want to scale?

[you] 5

[assistant] Statefulset has been updated. Anything else?

Supported voice commands

Scale statefulset "name"

Scale deployment "name"

Scale replicaset "name"

What is the size of the cluster?

Contribute to add more voice commands :)

How it works

Generate kubeconfig

To generate kubeconfig you have to install the following tools:

  • kubectl
  • cfssl
  • cfssljson

Then run the following command to generate build/kubeconfig file.

./generate-kubeconfig.sh

Deploy to Google App Engine

Requirements:

  • gcloud

Set environment variables in env.yaml (cp env.sample.yaml env.yaml).

gcloud app deploy

Save URL, you will need to use it later in Dialogflow.

API deployed to App Engine is protected by static API Key which should be set in env.yaml. To access API, client should send Authorization: Bearer ${API_KEY} header.

Configure in Dialogflow

  1. Go to Dialogflow Console
  2. Select or create a new agent
  3. Go to Settings -> Export and Import
  4. Select Import From Zip (import this file google-home-k8s.zip)
  5. Go to Fulfillment
  6. Enable Webhook
  7. Paste URL to API deployed to App Engine
  8. Add Header. Key: Authorization, Value: Bearer API_KEY (replace API_KEY with the value from env.yaml)
