Create a cluster

This page explains how to create a cluster in Google Kubernetes Engine (GKE) with Binary Authorization enabled. You perform this step at the command line using gcloud commands or in the Google Cloud console. This step is part of setting up Binary Authorization for GKE.

Before you begin

• Enable Binary Authorization.

• Enable the GKE API.

  Enable the API

• Configure a platform policy using the Google Cloud console, command-line tool, or REST API.

Create a cluster with Binary Authorization enabled (CV monitoring-only)

Binary Authorization works with Autopilot or Standard clusters. To configure monitoring-only evaluation mode, you must specify at least one check-based platform policy.

To create a cluster with Binary Authorization enabled with only CV monitoring, do the following:

Console

The following steps configure a Standard cluster.

1. In the Google Cloud console, go to the GKE page.

   Go to GKE

2. Click Create Cluster. Enter values for the default fields as described in Creating a zonal cluster.

3. In the navigation menu, click Security.

4. Select Enable Binary Authorization. 1. Select Audit-only and configure CV check-based platform policies that you want Binary Authorization to evaluate your cluster's images against.

5. Click Create.

gcloud

1. Set your default Google Cloud project:

   gcloud config set project PROJECT_ID
   

   Replace PROJECT_ID with the ID of the project where you want to create the cluster.

2. Create a cluster that uses only CV platform policy-based monitoring:

   Before using any of the command data below, make the following replacements:

   • CLUSTER_NAME: a cluster name.
   • LOCATION: the location—for example, us-central1 or asia-south1.
   • POLICY_PROJECT_ID: the ID of the project where the policy is stored.
   • POLICY_ID: the policy ID.
   • CLUSTER_PROJECT_ID: the cluster project ID.

   Execute the following command:

   Linux, macOS, or Cloud Shell

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME \
       --location=LOCATION \
       --binauthz-evaluation-mode=POLICY_BINDINGS \
       --binauthz-policy-bindings=name=projects/POLICY_PROJECT_ID/platforms/gke/policies/POLICY_ID \
       --project=CLUSTER_PROJECT_ID

   Windows (PowerShell)

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME `
       --location=LOCATION `
       --binauthz-evaluation-mode=POLICY_BINDINGS `
       --binauthz-policy-bindings=name=projects/POLICY_PROJECT_ID/platforms/gke/policies/POLICY_ID `
       --project=CLUSTER_PROJECT_ID

   Windows (cmd.exe)

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME ^
       --location=LOCATION ^
       --binauthz-evaluation-mode=POLICY_BINDINGS ^
       --binauthz-policy-bindings=name=projects/POLICY_PROJECT_ID/platforms/gke/policies/POLICY_ID ^
       --project=CLUSTER_PROJECT_ID

Important: The cluster creation process does not check the validity or existence of the provided platform policies. Platform policy validity is checked only during the periodic monitoring cycles. Take extra caution in ensuring platform policies exist, are formatted appropriately, and have no typographical errors prior to cluster creation.

It can take a few minutes for your cluster to be created.

Create a cluster with Binary Authorization enabled (enforce-only)

Binary Authorization works with Autopilot or Standard clusters. The enforcement policy is set to the project policy which by default allows all images. To change the project policy follow these instructions.

To create a cluster with Binary Authorization enabled with only enforcement enabled, do the following:

Console

The following steps configure a Standard cluster.

1. In the Google Cloud console, go to the GKE page.

   Go to GKE

2. Click Create Cluster. Enter values for the default fields as described in Creating a zonal cluster.

3. In the navigation menu, click Security.

4. Select Enable Binary Authorization.

5. Select Enforce-only.

6. Click Create.

gcloud

1. Set your default Google Cloud project:

   gcloud config set project PROJECT_ID
   

   Replace PROJECT_ID with the ID of the project where you want to create the cluster.

2. Create a cluster that uses policy enforcement only:

   Before using any of the command data below, make the following replacements:

   • CLUSTER_NAME: a cluster name.
   • LOCATION: the location—for example, us-central1 or asia-south1.
   • CLUSTER_PROJECT_ID: the cluster project ID.

   Execute the following command:

   Linux, macOS, or Cloud Shell

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME \
       --location=LOCATION \
       --binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE \
       --project=CLUSTER_PROJECT_ID

   Windows (PowerShell)

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME `
       --location=LOCATION `
       --binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE `
       --project=CLUSTER_PROJECT_ID

   Windows (cmd.exe)

   Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

   gcloud beta container clusters create CLUSTER_NAME ^
       --location=LOCATION ^
       --binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE ^
       --project=CLUSTER_PROJECT_ID

Terraform

The following Terraform example creates and configures a Standard cluster:

resource "google_container_cluster" "default" {
  name               = "gke-standard-regional-binauthz-enforce"
  location           = "us-west1"
  initial_node_count = 1

  binary_authorization {
    evaluation_mode = "PROJECT_SINGLETON_POLICY_ENFORCE"
  }
}

To learn more about using Terraform, see Terraform support for GKE.

It can take a few minutes for your cluster to be created.

Create a cluster with Binary Authorization enabled (CV monitor and enforce)

Binary Authorization works with Autopilot or Standard clusters.

For enforcement, the policy is set to the project policy which by default allows all images. To change the project policy follow these instructions.

For CV monitoring, you must specify at least one CV check-based platform policy.

To create a cluster with Binary Authorization enabled with both CV monitoring and enforcement, do the following:

Console

The following steps configure a Standard cluster.

1. In the Google Cloud console, go to the GKE page.

   Go to GKE

2. Click Create Cluster. Enter values for the default fields as described in Creating a zonal cluster.

3. In the navigation menu, click Security.

4. Select Enable Binary Authorization.

5. Select Audit and Enforce and configure CV check-based platform policies.
