This page shows you how to create an Google Kubernetes Engine alpha cluster, which is a cluster with Kubernetes alpha features enabled in Google Kubernetes Engine. You can also read more about the types of clusters and about cluster architecture.
Before you begin
Before you start, make sure you have performed the following tasks:
- Ensure that you have enabled the Google Kubernetes Engine API. Enable Google Kubernetes Engine API
- Ensure that you have installed the Cloud SDK.
Set up default gcloud
settings using one of the following methods:
- Using
gcloud init
, if you want to be walked through setting defaults. - Using
gcloud config
, to individually set your project ID, zone, and region.
Using gcloud init
If you receive the error One of [--zone, --region] must be supplied: Please specify
location
, complete this section.
-
Run
gcloud init
and follow the directions:gcloud init
If you are using SSH on a remote server, use the
--console-only
flag to prevent the command from launching a browser:gcloud init --console-only
-
Follow the instructions to authorize
gcloud
to use your Google Cloud account. - Create a new configuration or select an existing one.
- Choose a Google Cloud project.
- Choose a default Compute Engine zone for zonal clusters or a region for regional or Autopilot clusters.
Using gcloud config
- Set your default project ID:
gcloud config set project PROJECT_ID
- If you are working with zonal clusters, set your default compute zone:
gcloud config set compute/zone COMPUTE_ZONE
- If you are working with Autopilot or regional clusters, set your default compute region:
gcloud config set compute/region COMPUTE_REGION
- Update
gcloud
to the latest version:gcloud components update
- Ensure you have the correct permission to create clusters. At minimum, you should be a Kubernetes Engine Cluster Admin.
- Be sure you understand the limitations of alpha clusters.
Creating an alpha cluster
You can create an alpha cluster by using the gcloud
tool or the
Google Cloud Console.
gcloud
Run the following command:
gcloud container clusters create cluster-name \ --enable-kubernetes-alpha \ [--zone compute-zone] \ [--cluster-version version]
Replace the following:
- cluster-name: the name you choose for the cluster.
compute-zone the zone in which to create the cluster. The optional
--zone
flag overrides the defaultcompute/zone
property set bygcloud config set compute/zone
.version: the GKE version to run in the cluster. If unset, the cluster runs the current default version documented in Versioning and upgrades.
You are prompted to acknowledge a warning that the alpha cluster is not upgraded and is deleted after 30 days:
This will create a cluster with all Kubernetes Alpha features enabled. - This cluster will not be covered by the GKE SLA and should not be used for production workloads. - You will not be able to upgrade the master or nodes. - The cluster will be deleted after 30 days.
Console
Visit the Google Kubernetes Engine menu in Cloud Console.
Click add_box Create.
In the Cluster basics section, complete the following:
- Enter the Name for your cluster.
- For the Location type, select Zonal, and then select the desired zone for your cluster.
- If you are creating a multi-zonal cluster, select the Specify default node locations checkbox, and then choose additional zones in which you'd like the cluster to run.
For the Master Version, select Static version, then choose a GKE version.
From the navigation pane, under Node Pools, click default-pool.
In the Node pool details section, complete the following:
- Enter a Name for the default Node pool.
- For static version nodes, choose the Node version.
- Enter the Number of nodes to create in the cluster. You must have available resource quota for the nodes and their resources (such as firewall routes).
- Clear Enable auto-upgrade and Enable auto-repair.
From the navigation pane, under Node Pools, click Nodes.
From the Image type drop-down list, select the desired node image.
Choose the default Machine configuration to use for the instances. Each machine type is billed differently. The default machine type is
e2-medium
. For machine type pricing information, refer to the machine type price sheet.From the Boot disk type drop-down list, select the desired disk type.
Enter the Boot disk size.
From the navigation pane, under Cluster, click Features.
Click Enable Kubernetes alpha features in this cluster.
Read and acknowledge the warning by selecting I understand the consequences.
Click Create.
After you create a cluster, you need to
configure kubectl
before you can interact with the cluster from the command line.
Check when an alpha cluster expires
To check when alpha clusters expire, run the following command:
gcloud container clusters list
