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:
gcloud init, if you want to be walked through setting defaults.
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.
gcloud initand follow the directions:
If you are using SSH on a remote server, use the
--console-onlyflag to prevent the command from launching a browser:
gcloud init --console-only
Follow the instructions to authorize
gcloudto 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.
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 regional clusters, set your default compute region:
gcloud config set compute/region COMPUTE_REGION
gcloudto 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.
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
--zoneflag overrides the default
compute/zoneproperty set by
gcloud config set compute/zone.
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.
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, and then choose a GKE version.
From the navigation pane, under Node Pools, click default-pool.
In the Node pool details section, complete the following:
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.
After you create a cluster, you need to
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
