Minikube

Follow these steps to create a Minikube cluster for your Agones install.

Installing Minikube

First, install Minikube, which may also require you to install a virtualisation solution, such as VirtualBox as well.

Starting Minikube

Minikube will need to be started with the supported version of Kubernetes that is supported with Agones, via the --kubernetes-version command line flag.

Optionally, we also recommend starting with an agones profile, using -p to keep this cluster separate from any other clusters you may have running with Minikube.

minikube start --kubernetes-version v1.21.5 -p agones

Check the official minikube start reference for more options that may be required for your platform of choice.

Known working drivers

Other operating systems and drivers may work, but at this stage have not been verified to work with UDP connections via Agones exposed ports.

Linux

  • kvm2

Mac

  • Docker (default)
  • Hyperkit

Windows

If you have successfully tested with other platforms and drivers, please click “edit this page” in the top right hand side and submit a pull request to let us know.

Local connection workarounds

Depending on your operating system and virtualization platform that you are using with Minikube, it may not be possible to connect directly to a GameServer hosted on Agones as you would on a cloud hosted Kubernetes cluster.

If you are unable to do so, the following workarounds are available, and may work on your platform:

minikube ip

Rather than using the published IP of a GameServer to connect, run minikube ip -p agones to get the local IP for the minikube node, and connect to that address.

Create a service

This would only be for local development, but if none of the other workarounds work, creating a Service for the GameServer you wish to connect to is a valid solution, to tunnel traffic to the appropriate GameServer container.

Use the following yaml:

apiVersion: v1
kind: Service
metadata:
  name: agones-gameserver
spec:
  type: LoadBalancer
  selector:
    agones.dev/gameserver: ${GAMESERVER_NAME}
  ports:
  - protocol: UDP
    port: 7000 # local port
    targetPort: ${GAMESERVER_CONTAINER_PORT}

Where ${GAMESERVER_NAME} is replaced with the GameServer you wish to connect to, and ${GAMESERVER_CONTAINER_PORT} is replaced with the container port GameServer exposes for connection.

Running minikube service list -p agones will show you the IP and port to connect to locally in the URL field.

To connect to a different GameServer, run kubectl edit service agones-gameserver and edit the ${GAMESERVER_NAME} value to point to the new GameServer instance and/or the ${GAMESERVER_CONTAINER_PORT} value as appropriate.

Use a different driver

If you cannot connect through the Serviceor use other workarounds, you may want to try a different minikube driver, and if that doesn’t work, connection via UDP may not be possible with minikube, and you may want to try either a different local Kubernetes tool or use a cloud hosted Kubernetes cluster.
