GKE with Workload Identity only: Configure Workload Identity

Note: Apigee hybrid v.1.11 only supports Workload Identity federation on GKE.

Follow these steps if you set up your overrides file for Workload Identity on GKE in Step 6: Configure the cluster.

If you are not using Workload Identity on GKE, proceed to Part 3, Step 1: Expose Apigee ingress gateway.

Google Cloud service accounts and Kubernetes service accounts

A Google Cloud service account is a special kind of account that can be used to make authorized API calls by authenticating as the service account itself. Google Cloud service accounts can be given roles and permissions similar to an individual user. When an application authenticates as a service account, it has access to all resources that the service account has permission to access. If you want to learn more about Google Cloud service accounts, see Service accounts overview.

You created Google Cloud service accounts for your Apigee hybrid installation in Step 4: Create service accounts. Apigee uses these service accounts to authenticate the hybrid components.

Kubernetes service accounts are similar to Google Cloud service accounts. A Kubernetes service account provides an identity for processes that run in a Pod, and allows it to authenticate to the API server similarly to a user. If you want to learn more about Kubernetes service accounts, see Configure Service Accounts for Pods.

The apigeectl tool created most of the Kubernetes service accounts needed by Apigee hybrid when you ran apigeectl apply in the previous procedure.

When you configure Workload Identity on GKE, you associate the Google Cloud service accounts with the Kubernetes service accounts in the Kubernetes cluster. That way, the Kubernetes service accounts can impersonate the Google Cloud service accounts and use their assigned roles and permissions to authenticate with the hybrid components.

Follow these instructions to configure Workload Identity for your project.

Note: Workload Identity is only available for hybrid installations on GKE.

Prepare to configure Workload Identity

These procedures make use of the following environment variables. Check that they are defined and define any that are not:

echo $APIGEECTL_HOME
echo $CLUSTER_LOCATION
echo $ENV_NAME
echo $HYBRID_FILES
echo $NAMESPACE
echo $PROJECT_ID
echo $ORG_NAME

1. Check that the current gcloud configuration is set to your Google Cloud project ID with the following command:

   gcloud config get project

If needed, set the current gcloud configuration:

gcloud config set project $PROJECT_ID

2. Create the apigee-cassandra-restore Kubernetes service account.

   When you applied your configuration by running apigeectl apply, the command created most of the Kubernetes service accounts needed for Workload Identity.

   To create the apigee-cassandra-restore Kubernetes service account, run apigeectl apply with the --restore flag:

   $APIGEECTL_HOME/apigeectl apply -f $HYBRID_FILES/overrides/overrides.yaml --restore

3. Verify that Workload Identity is enabled for your GKE Cluster. When you created the cluster in Step 1: Create a cluster, step 6 was to Enable Workload Identity. You can confirm if Workload Identity is enabled by running the following command:

   Regional clusters

   gcloud container clusters describe $CLUSTER_NAME \
     --region $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten 'workloadIdentityConfig'

   Zonal clusters

   gcloud container clusters describe $CLUSTER_NAME \
     --zone $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten 'workloadIdentityConfig'

   Your output should look like the following:

     ---
     workloadPool: PROJECT_ID.svc.id.goog

   If you see null instead in your results, run the following command to enable Workload Identity for your cluster:

   Regional clusters

   gcloud container clusters update $CLUSTER_NAME \
     --workload-pool=$PROJECT_ID.svc.id.goog \
     --project $PROJECT_ID \
     --region $CLUSTER_LOCATION

   Zonal clusters

   gcloud container clusters update  $CLUSTER_NAME \
     --workload-pool=$PROJECT_ID.svc.id.goog \
     --zone $CLUSTER_LOCATION \
     --project $PROJECT_ID

4. Enable Workload Identity for each node pool with the following commands. This operation can take up to 30 minutes for each node:

   Regional clusters

   gcloud container node-pools update NODE_POOL_NAME \
     --cluster=$CLUSTER_NAME \
     --region $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --workload-metadata=GKE_METADATA

   Zonal clusters

   gcloud container node-pools update NODE_POOL_NAME \
     --cluster=$CLUSTER_NAME \
     --zone $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --workload-metadata=GKE_METADATA

   Where NODE_POOL_NAME is the name of each node pool. In most Apigee hybrid installations, the two default node pools are named apigee-data and apigee-runtime.

5. Verify that Workload Identity is enabled on your node pools with the following commands:

   Regional clusters

   gcloud container node-pools describe apigee-data \
     --cluster $CLUSTER_NAME \
     --region $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten "config:"

   gcloud container node-pools describe apigee-runtime \
     --cluster $CLUSTER_NAME \
     --region $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten "config:"

   Zonal clusters

   gcloud container node-pools describe apigee-data \
     --cluster $CLUSTER_NAME \
     --zone $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten "config:"

   gcloud container node-pools describe apigee-runtime \
     --cluster $CLUSTER_NAME \
     --zone $CLUSTER_LOCATION \
     --project $PROJECT_ID \
     --flatten "config:"

   Your output should look something like:

   ---
   diskSizeGb: 100
   diskType: pd-standard
   ...
   workloadMetadataConfig:
     mode: GKE_METADATA
       

6. Get a list of the names of the Google Cloud service accounts for your project. You will need these names to associate the Kubernetes service accounts to configure Workload Identity. For non-production installations, there should be only one Google service account. For production installations there should be eight.

   Use the following command to get the list of names:

   gcloud iam service-accounts list --project $PROJECT_ID

   Your output should look something like:

   Non-prod

   For non-production environments:

   DISPLAY NAME         EMAIL                                                      DISABLED
   apigee-non-prod      apigee-non-prod@my_project_id.iam.gserviceaccount.com      False
   

   Production

   For non-production environments:

   DISPLAY NAME         EMAIL                                                      DISABLED
   apigee-cassandra     apigee-cassandra@my_project_id.iam.gserviceaccount.com     False
   apigee-logger        apigee-logger@my_project_id.iam.gserviceaccount.com        False
   apigee-mart          apigee-mart@my_project_id.iam.gserviceaccount.com          False
   apigee-metrics       apigee-metrics@my_project_id.iam.gserviceaccount.com       False
   apigee-runtime       apigee-runtime@my_project_id.iam.gserviceaccount.com       False
   apigee-synchronizer  apigee-synchronizer@my_project_id.iam.gserviceaccount.com  False
   apigee-udca          apigee-udca@my_project_id.iam.gserviceaccount.com          False
   apigee-watcher       apigee-watcher@my_project_id.iam.gserviceaccount.com       False
   

   Tip: If you have custom names for your service accounts that do not correspond easily with the names of the Apigee components, you can determine the role of each service account by checking the roles assigned to it and comparing the roles with the roles recommended in About service accounts.

   Use the following command to check the roles assigned to a service account:

   gcloud projects get-iam-policy ${PROJECT_ID}  \
     --flatten="bindings[].members" \
     --format='table(bindings.role)' \
     --filter="SERVICE_ACCOUNT_NAME"

7. Get a list of names of the Kubernetes service accounts. You will need this list of names to associate with your Google Cloud service accounts later in this procedure. Use the following command:

   kubectl get sa -n $NAMESPACE

   Your output should look something like the following. The Kubernetes service accounts in bold are the ones you will need to associate with your Google cloud service accounts:

   NAME                                                         SECRETS   AGE

Configure Workload Identity

Use the following procedure to enable Workload Identity for your Hybrid installation:

1. For each Apigee component annotate the corresponding Kubernetes service accounts with the Google service account for the component.
   IMPORTANT: If your service account names do not match the default names created by create-service-account, replace the red service account name with the correct service account name for the component in the following commands. For example, if your Cassandra service account is named my-cassandra-accnt-1, then replace apigee-cassandra with that name in the command.

   The following steps use two environment variables. You will reset the values of these variables before each set of commands:

   • GSA_NAME: The name of a Google service account. These are the service accounts you created with the create-service-account tool in Step 4: Create service accounts.
   • KSA_NAME: The name of a Kubernetes service account. These are the accounts you listed above with the kubectl get sa -n $NAMESPACE command, for example: apigee-cassandra-schema-setup-hybrid-example-project-123abcd-sa.
   Tip: If you encounter an error saying the service account is "NOT FOUND," try running gcloud init to set the current configuration to the correct Google Cloud project ID and cluster location.
• Cassandra

  Configure Workload Identity for the Cassandra component.

  The Cassandra component has six associated Kubernetes service accounts:

  • apigee-cassandra-backup
  • apigee-cassandra-restore
  • apigee-cassandra-schema-setup
  • apigee-cassandra-schema-val (val = validation)
  • apigee-cassandra-user-setup
  • apigee-datastore-default

  Non-prod

  Configure the apigee-cassandra-backup Kubernetes service account

  1. Define the KSA_NAME and GSA_NAME environment variables:

     GSA_NAME="apigee-non-prod"
     KSA_NAME="apigee-cassandra-backup"

  2. Bind the IAM role:

2. Optional: Delete the any downloaded service account key files.

   If you created the Google service accounts with the create-service-account tool, it may have created service account keys and downloaded the .json key files. When using Workload Identity on GKE, you do not need these key files.

   You can delete the key files with the following command:

   rm $HYBRID_FILES/service-accounts/*.json

Verify Workload Identity

1. (Optional) You can see the status of your Kubernetes service accounts in the Kubernetes: Workloads Overview page in the Google Cloud Console.

   Go to Workloads

   Note: You may see an error status for the apigee-cassandra-backup and apigee-cassandra-restore service accounts. This is because you are not currently running backup or restore, and these processes have not been fully configured yet. For more information on Cassandra backup and restore, see feedbackCassandra backup overview.
2. To check the status of the deployment again with apigeectl check-ready:

   ${APIGEECTL_HOME}/apigeectl check-ready -f ${HYBRID_FILES}/overrides/overrides.yaml

Congratulations!

You've successfully configured Workload Identity for your hybrid clusters. In the next step, you will configure the Apigee ingress gateway.
