This topic explains how to enable Workload Identity for Apigee hybrid using apigeectl.

If you are using Helm charts to install and manage Apigee hybrid, see Enabling Workload Identity with Helm charts.

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

Overview

Workload Identity is a way for applications running within GKE (Google Kubernetes Engine) to access Google Cloud services. For overviews of Workload Identity, see:

• Introducing Workload Identity: Better authentication for your GKE applications
• Using Workload Identity

A Google Cloud IAM service account is an identity that an application can use to make requests to Google APIs. These service accounts are referred to as GSA (Google Service Accounts) in the document. For more information about GSAs, see Service accounts.

Separately, Kubernetes also has the concept of service accounts. A service account provides an identity for processes that run in a Pod. Kubernetes service accounts are Kubernetes resources, while Google service accounts are specific to Google Cloud. For information on Kubernetes service accounts, see Configure Service Accounts for Pods in the Kubernetes documentation.

With Apigee hybrid 1.4 and later, Apigee creates and uses a Kubernetes service account for each type of component. Enabling Workload Identity allows the hybrid components to interact with the Kubernetes service accounts.

Google service accounts in Apigee hybrid without Workload Identity

Without using Workload Identity, you must link the Google service accounts to each component in your overrides.yaml file with either a reference to a cert file or a Kubernetes secret. For example:

• Cert files:

  watcher:
    serviceAccountPath: ./apigee-org/my-hybrid-project-apigee-watcher.json

  See:

  cassandra.backup.serviceAccountPath cassandra.restore.serviceAccountPath connectAgent.serviceAccountPath diagnostic.serviceAccountPath envs[].serviceAccountPaths.runtime envs[].serviceAccountPaths.synchronizer envs[].serviceAccountPaths.udca

  logger.serviceAccountPath mart.serviceAccountPath metrics.serviceAccountPath synchronizer.serviceAccountPath udca.serviceAccountPath watcher.serviceAccountPath

• Kubernetes secret:

  watcher:
    serviceAccountRef: my-watcher-k8s-secret

  See:

  cassandra.backup.serviceAccountRef cassandra.restore.serviceAccountRef connectAgent.serviceAccountRef diagnostic.serviceAccountRef envs[].serviceAccountRefs.runtime envs[].serviceAccountRefs.synchronizer envs[].serviceAccountRefs.udca

  logger.serviceAccountRef mart.serviceAccountRef metrics.serviceAccountRef synchronizer.serviceAccountRef udca.serviceAccountRef watcher.serviceAccountRef

Environment variables used in these procedures

These procedures make use of the following environment variables. Either set these in your command shell or replace them in the code samples with the actual values:

• APIGEECTL_HOME: The directory where you have installed apigeectl.
• CLUSTER_LOCATION: The region or zone of your cluster, for example: us-west1.
• ENV_NAME: Then name of the Apigee environment.
• HYBRID_FILES: Your hybrid files directory, for example hybrid-base-directory/hybrid-files.
• ORG_NAME: The name of your Apigee organization.
• PROJECT_ID: The ID of your Google Cloud project.
• NAMESPACE: Your Apigee namespace (usually "apigee").

Verify the environment variables:

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

Initialize any of the variables you need:

export PROJECT_ID=my-project-id
export ORG_NAME=$PROJECT_ID
export ENV_NAME=my-environment-name
export NAMESPACE=apigee
export CLUSTER_LOCATION=my-cluster-location
export APIGEECTL_HOME=hybrid-base-directory/apigeectl
export HYBRID_FILES=hybrid-base-directory/hybrid-files

Workload Identity and service account key files

When running Apigee hybrid on GKE, the standard practice is to create and download private keys (.json files) for each of the service accounts. When using Workload Identity, you do not need to download service account private keys and add them to GKE clusters.

If you have downloaded service account key files as part of your Apigee hybrid installation, you can delete them after enabling Workload Identity. In most installations, they reside in the hybrid-base-directory/hybrid-files/service-accounts/ directory.

Enable Workload Identity for Apigee hybrid

To begin, follow the instructions in Prepare to enable Workload Identity to update node pools and initialize variables prior to enabling Workload Identity.

Then, follow the instructions in Set workloadIdentityEnabled: true and create service accounts to enable Workload Identity on your Apigee hybrid installation.

Prepare to enable Workload Identity

Before starting the install process, follow the steps in this section.

1. Set the project to the project you're modifying:

   gcloud config set project $PROJECT_ID

2. Get the gcloud credentials of the cluster on which you are enabling Workload Identity with the following command:

   gcloud container clusters get-credentials ${CLUSTER_NAME} \
     --region ${CLUSTER_LOCATION} \
     --project ${PROJECT_ID}

   Note: If you created a zonal cluster instead of a regional cluster, get the credentials with the following command:

   gcloud container clusters get-credentials ${CLUSTER_NAME} \
     --zone ${CLUSTER_LOCATION} \
     --project ${PROJECT_ID}

3. Verify that Workload Identity is enabled for the GKE cluster running Apigee with the following command:

   gcloud container clusters describe $CLUSTER_NAME --region $CLUSTER_LOCATION --project $PROJECT_ID

   Note: For zonal clusters use:

   gcloud container clusters describe $CLUSTER_NAME --zone $CLUSTER_LOCATION --project $PROJECT_ID

   The output should include something like the following:

   …
     …
     status: RUNNING
     subnetwork: default
     workloadIdentityConfig:
       workloadPool: my-project-id.svc.id.goog

   If needed, enable workload identity on the cluster. This operation can take up to 30 minutes:

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

   Note: If you created a zonal cluster instead of a regional cluster, use the --zone argument instead of --region as in the following command:

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

   For more information, see Enable Workload Identity.

4. Ensure Workload Identity is enabled on each node pool.
   1. List your node pools with the following command:

      gcloud container node-pools list \
        --cluster $CLUSTER_NAME \
        --region $CLUSTER_LOCATION \
        --project $PROJECT_ID

      Your output should look something like:

        NAME            MACHINE_TYPE   DISK_SIZE_GB  NODE_VERSION
        apigee-runtime  e2-standard-4  100           1.23.12-gke.100
        apigee-data     e2-standard-4  100           1.23.12-gke.100

   2. Ensure Workload Identity is enabled per node pool using the following command for each node pool:

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

      Where NODE_POOL_NAME is the name of each node pool.

Verify or create Google service accounts

Google service accounts are created for many Apigee hybrid components during installation. Use this procedure to verify the Google service accounts and create any that are needed.

1. Check the names of the Google service accounts for your project with the following command:

   gcloud iam service-accounts list --project $PROJECT_ID

   Your output should look something like:

   Prod

   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
   

   Non-prod

   For non-production environments:

   DISPLAY NAME         EMAIL                                                      DISABLED
   apigee-non-prod      apigee-non-prod@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"

   If you need to create the Google service accounts for your project, there are two methods you can use:

   • Use the create-service-account tool included with apigee in the apigeectl/tools/ directory. This tool can create all the service accounts with a single command or let you create them individually.
     create-service-account generates key files for each service account and downloads them. Using Workload Identity, you will not need these key files. If you are concerned about the security of these key files, you may want to delete them. Alternatively you can use gcloud to create the service accounts and assign the appropriate roles to them.
   • Use the gcloud iam service-accounts create command to create the service accounts one at a time and the gcloud projects add-iam-policy-binding command to assign the appropriate roles to each service account. This method requires you to create each service account individually, but lets you avoid downloading the key files.

   create-service-account

   Use the following command to create a Google service account per component:

   Prod

   For non-production environments:

   $APIGEECTL_HOME/tools/create-service-account --env prod --dir $APIGEECTL_HOME/../service-accounts

   This command will create the following service accounts:

   • apigee-cassandra
   • apigee-logger
   • apigee-mart
   • apigee-metrics
   • apigee-runtime
   • apigee-synchronizer
   • apigee-udca
   • apigee-watcher

   Non-prod

   For non-production environments:

   $APIGEECTL_HOME/tools/create-service-account --env non-prod --dir $APIGEECTL_HOME/../service-accounts

   This command will create a single service accounts, apigee-non-prod, with all the roles assigned needed to manage all Apigee components.

   gcloud

   Create the following service accounts and assign roles to them.

   Tip: If you want to use custom names, change the red service account name in the code sample to the name you want to use.

   1. Service account: apigee-cassandra, role: roles/storage.objectAdmin

      Create the account:

      gcloud iam service-accounts create apigee-cassandra \

      Assign the role:

      gcloud projects add-iam-policy-binding $PROJECT_ID \
        --member="serviceAccount:apigee-cassandra@$PROJECT_ID.iam.gserviceaccount.com" \

      Assign the role:

      gcloud projects add-iam-policy-binding $PROJECT_ID \
        --member="serviceAccount:apigee-metrics@$PROJECT_ID.iam.gserviceaccount.com" \
        --role="roles/monitoring.metricWriter"
                  

   5. Service account: apigee-runtime, role: No role assigned.

      Create the account:

Set workloadIdentityEnabled: true and create service accounts

apigeectl creates Kubernetes service accounts for each Apigee hybrid component when you set workloadIdentityEnabled: true in your overrides file and apply the changes.

1. Add the bolded line below to your overrides.yaml file under the gcp stanza. This enables Workload Identity for your installation and triggers apigeectl to create the Kubernetes service accounts when you apply the configuration:

   gcp:
     projectID: "my-project-id"
     name: "my-project-id"
     region: "analytics-region"
     workloadIdentityEnabled: true

2. Add the bolded lines below to your overrides.yaml file under the cassandra stanza. This triggers the creation of the apigee-cassandra-backup Kubernetes service account:

   cassandra:
     ...
     backup:
       enabled: true

3. Apply the changes with apigeectl with the --restore flag:

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

   Note: The --restore flag triggers creation of the apigee-cassandra-restore Kubernetes service account.
4. Verify the service accounts with 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 annotate with your Google service accounts:

   NAME                                                         SECRETS   AGE

Annotate the Kubernetes service accounts with the Google service accounts

For each Apigee component annotate the corresponding Kubernetes service accounts with the Google service account for the component.

Org-level components

You will have only one instance of each Kubernetes service account for your Apigee org.

Component	Kubernetes Service Account	Google Service Account
Cassandra	apigee-cassandra-backup	apigee-cassandra
	apigee-cassandra-restore	apigee-cassandra
	apigee-cassandra-schema-setup-my-project-id-num-id1-sa	apigee-cassandra
	apigee-cassandra-schema-val-my-project-id-num-id1	apigee-cassandra
	apigee-cassandra-user-setup-my-project-id-num-id1-sa	apigee-cassandra
	apigee-datastore-default-sa	apigee-cassandra
Apigee Connect	apigee-connect-agent-my-project-id-num-id1-sa	apigee-mart
MART	apigee-mart-my-project-id-num-id1-sa	apigee-mart
Metrics	apigee-metrics-sa	apigee-metrics
UDCA (org-level)	apigee-udca-my-project-id-num-id1-sa	apigee-udca
Watcher	apigee-watcher-my-project-id-num-id1-sa	apigee-watcher

Env-level components

You will have one instance of each Kubernetes service account for each Apigee environment.

Component	Kubernetes Service Account	Google Service Account
Apigee Runtime	apigee-runtime-my-project-id-env-name-num-id2-sa	apigee-runtime
Synchronizer	apigee-synchronizer-my-project-id-env-name-num-id2-sa	apigee-synchronizer
UDCA (env-level)	apigee-udca-my-project-id-env-name-num-id2-sa	apigee-udca

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

In the following commands use the Kubernetes service account names returned by the kubectl get sa -n $NAMESPACE command, for example: apigee-cassandra-schema-val-hybrid-example-project-123abcd.

In this procedure, for each Kubernetes service account, you will:

• Bind the Kubernetes service account and the principal Google service account to the roles/iam.workloadIdentityUser IAM role.
• Annotate the Kubernetes service account with the Google service account.

1. Bind the roles and annotate the service accounts.

   Org-level components

   Annotate Kubernetes service accounts for the org-level components. You will need to do this once for each component in your Apigee organization.

   • Cassandra

     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

     Prod

     apigee-cassandra-backup

     1. Define the KSA_NAME and GSA_NAME environment variables:

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

     2. Bind the IAM role:

        gcloud iam service-accounts add-iam-policy-binding \
          --role roles/iam.workloadIdentityUser \
          --member "serviceAccount:$PROJECT_ID.svc.id.goog[$NAMESPACE/$KSA_NAME]" \
          $GSA_NAME@$PROJECT_ID.iam.gserviceaccount.com

     3. Annotate the service account:

        kubectl annotate serviceaccount \
          --namespace $NAMESPACE $KSA_NAME iam.gke.io/gcp-service-account=$GSA_NAME@$PROJECT_ID.iam.gserviceaccount.com
