kubeleans
Demo project for running an Orleans silo in Kubernetes.
Instructions
- Set up your kubernetes-docker environment. There are two ways to do this:
- Using the Docker Kubernetes system in the Edge version of Docker. This is the easiest way, and I recommend it, but (as of this writing) it is only available in Docker for macOS.
- Using Minikube. Once you've set up Minikube, make sure you've run
eval $(minikube docker-env)before continuing.
- Clone this repo
- Run
make
What this will do
This first builds two containers: kubeleans:silo and kubeleans:client. The silo runs an Orleans silo with some simple dummy grains. The client runs a webapp that's a slightly tweaked version of the basic boilerplate that you get when you run dotnet new reactredux.
Next, it uses kubectl to deploy:
- A namespace. This is so that you can easily clean this up later by just deleting the
kubeleansnamespace. - A NodePort service. This is what exposes the web app pod to the network
- A silo deployment. This is 3 separate identical pods that all run the silo code and participate in an Orleans cluster.
- A webapp deployment. This is a web application, exposed by the above NodePort, that will connect to the Orleans cluster and make requests to it.
Give this about 30 seconds to start up, then navigate to http://localhost:30000. You should see the friendly dotnet welcome page. Click the "Food data" link on the left and you'll see a table load by making requests to the Orleans cluster.
Cleaning up
You can run make clean to delete the namespace in Kubernetes as well as removing the built images.
The Interesting Parts
Some of these projects have some pretty major boilerplate, so here are some links to the Orleans-relevant interesting content in the repo:
