f11r-operator
This controller is intended to help orchestrate prototype game server deployments.
Description
This repository defines a GameServer
custom resource for Kubernetes. Upon creating a GameServer
object, the controller will create a Pod with a port chosen from a configurable range and configure the underlying container to listen on that port. As of this moment, this system relies on host networking.
apiVersion: game.believer.dev/v1alpha1
kind: GameServer
metadata:
name: gameserver-sample
spec:
# optional display name override (Friendshipper uses this)
displayName: my cool server
# path to Unreal map to load
map: /Game/Levels/MyMap
# image tag to use for game server
version: my-tag-123
There is also a Playtest
custom resource which automatically provisions GameServer
objects based on some parameters.

Getting Started
You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster.
Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info
shows).
Running on the cluster
- Install Instances of Custom Resources:
kubectl apply -f config/samples/
- Build and push your image to the location specified by
IMG
:
make docker-build docker-push IMG=<some-registry>/f11r-operator:tag
- Deploy the controller to the cluster with the image specified by
IMG
:
make deploy IMG=<some-registry>/f11r-operator:tag
Uninstall CRDs
To delete the CRDs from the cluster:
make uninstall
Undeploy controller
UnDeploy the controller from the cluster:
make undeploy
Contributing
// TODO(user): Add detailed information on how you would like others to contribute to this project
How it works
This project aims to follow the Kubernetes Operator pattern.
It uses Controllers,
which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.
Test It Out
- Install the CRDs into the cluster:
make install
- Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
make run
NOTE: You can also run this in one step by running: make install run
Modifying the API definitions
If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
make manifests
NOTE: Run make --help
for more information on all potential make
targets
