Installing Agones on Google Kubernetes Engine using Terraform
Before you begin
Take the following steps to enable the Kubernetes Engine API:
- Visit the Kubernetes Engine page in the Google Cloud Platform Console.
- Create or select a project.
- Wait for the API and related services to be enabled. This can take several minutes.
- Enable billing for your project.
- If you are not an existing GCP user, you may be able to enroll for a $300 US Free Trial credit.
Choosing a shell
To complete this quickstart, we can use either Google Cloud Shell or a local shell.
Google Cloud Shell is a shell environment for managing resources hosted on Google Cloud Platform (GCP). Cloud Shell comes preinstalled with the gcloud and kubectl command-line tools.
gcloud provides the primary command-line interface for GCP, and
kubectl provides the command-line interface for running commands against Kubernetes clusters.
If you prefer using your local shell, you must install the gcloud and kubectl command-line tools in your environment.
To launch Cloud Shell, perform the following steps:
- Go to Google Cloud Platform Console
- From the top-right corner of the console, click the Activate Google Cloud Shell button:
- A Cloud Shell session opens inside a frame at the bottom of the console. Use this shell to run
Set a compute zone in your geographical region with the following command. The compute zone will be something like
us-west1-a. A full list can be found here.
gcloud config set compute/zone [COMPUTE_ZONE]
kubectl, perform the following steps:
- Install the Google Cloud SDK, which includes the
Initialize some default configuration by running the following command.
Do you want to configure a default Compute Region and Zone? (Y/n)?, enter
Yand choose a zone in your geographical region of choice.
kubectlcommand-line tool by running the following command:
gcloud components install kubectl
An example configuration can be found here: Terraform configuration with Agones submodule .
Copy this file into a local directory where you will execute the terraform commands.
The GKE cluster created from the example configuration will contain 3 Node Pools:
"default"node pool with
"game-server"tag, containing 4 nodes.
"agones-system"node pool for Agones Controller.
"agones-metrics"for monitoring and metrics collecting purpose.
"tiller" service account will be created with ClusterRole.
- project - your Google Cloud Project ID (required)
- name - the name of the GKE cluster (default is “agones-terraform-example”)
- agones_version - the version of agones to install (default is the latest version from the Helm repository)
- machine_type - machine type for hosting game servers (default is “n1-standard-4”)
- node_count - count of game server nodes for the default node pool (default is “4”)
- zone - the name of the zone you want your cluster to be created in. (default is “us-west1-c”)
- network - the name of the VPC network you want your cluster and firewall rules be connected to (default is “default”)
On the lines that read
source = "git::https://github.com/googleforgames/agones.git//install/terraform/modules/gke/?ref=master"
make sure to change
?ref=master to match your targeted Agones release, as Terraform modules can change between
For example, if you are targeting release release-1.4.0, then you will want to have
source = "git::https://github.com/googleforgames/agones.git//install/terraform/modules/gke/?ref=release-release-1.4.0"
as your source.
Creating the cluster
In the directory where you created
This will cause terraform to clone the Agones repository and use the
./install/terraform folder as starting point of
Agones submodule, which contains all necessary Terraform configuration files.
Next make sure that you can authenticate using gcloud:
gcloud auth application-default login
Now you can create your GKE cluster (optionally specifying the version of Agones you want to use):
terraform apply -var project="<YOUR_GCP_ProjectID>" [-var agones_version="1.0.0"]
To verify that the cluster was created successfully, set up your kubectl credentials:
gcloud container clusters get-credentials --zone us-west1-c agones-terraform-example
Then check that you have access to the Kubernetes cluster:
kubectl get nodes
You should have 6 nodes in
Uninstall the Agones and delete GKE cluster
To delete all resources provisioned by Terraform:
