KasmCloud

Managing and Running Actors, Providers, and Links in Kubernetes

⚠️Warning

This is a contributor-led experimental project and is not recommended to run in production at this time.

With each tag, it works fine, but there may be incompatible changes between tags.

Design

Combining WasmCloud with Kubernetes

Quick Start

  1. Deploy Nats
helm repo add nats https://nats-io.github.io/k8s/helm/charts/
helm repo update
helm upgrade --install kasmcloud-nats nats/nats
  1. Deploy KasmCloud CRDs and Webhook Server
kubectl apply -f ./deploy/crds
kubectl apply -f ./deploy/webhook
  1. Deploy KasmCloud Host
kubectl apply -f ./deploy/kasmcloud_host_rbac.yaml

# Deploy Default KasmCloud Host
kubectl apply -f ./deploy/kasmcloud_host_default.yaml

# [Optional] You can also deploy KasmCloud Host in each Kubernetes node.
kubectl apply -f ./deploy/kasmcloud_host_daemonset.yaml

# [Optional] You can also deploy as many temporary hosts as you want
# and change the number of temporary hosts by scaling the Deployment
kubectl apply -f ./deploy/kasmcloud_host_deployment.yaml
  1. Deploy Actor, Link and Provider Sample
kubectl apply -f ./sample.yaml

kubectl get kasmcloud

  1. curl echo server

RoadMap

  • Add KasmCloudHost resource
  • Add status information for the resource
  • Add Kasmcloud Repeater module
  • Add rolling updates for Actor
  • Add DaemonSet deployment for Actor
  • Blue/Green Deployment for Actors and Providers
