Enabling Workload Identity with Apigee hybrid

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

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:

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.
NAMESPACE: The Kubernetes namespace you are using for Apigee hybrid. Usually apigee.
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.

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 one of these sections, depending on the steps you're performing:

Enable Workload Identity for a fresh install. Follow these instructions for a new Apigee hybrid installation or if you have not already installed ASM on your hybrid installation.
Upgrade an installation to use Workload Identity. Follow these instructions to enable Workload Identity on your existing Apigee hybrid installation.

Prepare to enable Workload Identity

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

Set the project to the project you're modifying:
```
gcloud config set project $PROJECT_ID
```

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}

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.

Ensure Workload Identity is enabled on each node pool.

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

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.

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.

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

Create the account:

gcloud iam service-accounts create apigee-cassandra \
  --display-name="apigee-cassandra" \

  --member="serviceAccount:apigee-watcher@$PROJECT_ID.iam.gserviceaccount.com" \
  --role="roles/apigee.runtimeAgent"

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.

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
```
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
```
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.

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:

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.

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

Select a kubernetes service account to test, for example: apigee-cassandra-backup.

KSA_NAME="kubernetes-service-account-name"

kubectl run --rm -it --image google/cloud-sdk:slim \
  --namespace $NAMESPACE workload-identity-test\
  -- gcloud auth list

If you don't see a command prompt, try pressing Enter.

If the steps were correctly run, you should see a response like the following:

                   Credentialed Accounts
ACTIVE  ACCOUNT
*       GSA@PROJECT_ID.iam.gserviceaccount.com

If upgrading from a previous install, clean up secrets that contained service account private keys:

kubectl delete secrets -n $NAMESPACE $(k get secrets -n $NAMESPACE | grep svc-account | awk '{print $1}')

Check logs:

kubectl logs -n $NAMESPACE -l app=apigee=synchronizer,env=$ENV_NAME,org=$ORG_NAME apigee-synchronizer

Upgrade an install to use Workload Identity

Follow these instructions to add Workload Identity to an existing hybrid installation.

Here is a sample showing Google Service Accounts (GSA) created for Apigee:

gcloud iam service-accounts list --filter "apigee"

DISPLAY NAME       EMAIL                                                  DISABLED
apigee-cassandra   apigee-cassandra@PROJECT_ID.iam.gserviceaccount.com    False
apigee-connect     apigee-connect@PROJECT_ID.iam.gserviceaccount.com      False
apigee-runtime     apigee-runtime@PROJECT_ID.iam.gserviceaccount.com      False
apigee-metrics     apigee-metrics@PROJECT_ID.iam.gserviceaccount.com      False
apigee-mart        apigee-mart@PROJECT_ID.iam.gserviceaccount.com         False
apigee-watcher     apigee-watcher@PROJECT_ID.iam.gserviceaccount.com      False
apigee-sync        apigee-sync@PROJECT_ID.iam.gserviceaccount.com         False
apigee-udca        apigee-udca@$PROJECT_ID.iam.gserviceaccount.com        False

Here is a sample Kubernetes service accounts (KSA) created for Apigee:

kubectl get sa -n $NAMESPACE

apigee-cassandra-schema-setup-ORG_NAME-cb84b88-sa             1         xxd
apigee-cassandra-user-setup-ORG_NAME-cb84b88-sa               1         xxd

apigee-synchronizer-ORG_NAME-ENV_NAME-1d0dc5e-sa              1         xxd
apigee-udca-ORG_NAME-ENV_NAME-1d0dc5e-sa                      1         xxd
apigee-watcher-ORG_NAME-cb84b88                               1         xxd

Add the Workload Identity role to each service account:

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

For example, if you were setting the permissions for Apigee Synchronizer, you would run:

export KSA_NAME=$(kubectl get sa -n apigee -l app=apigee-synchronizer,env=$ENV_NAME,org=$ORG_NAME --output=jsonpath={.items..metadata.name})

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

Annotate each KSA with the GSA details:

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

For example, if you were setting the permissions for Apigee Synchronizer, you would run:

export KSA_NAME=$(kubectl get sa -n apigee -l app=apigee-synchronizer,env=$ENV_NAME,org=$ORG_NAME --output=jsonpath={.items..metadata.name})

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

Validate if the steps worked:

gcloud config set project $PROJECT_ID

kubectl run --rm -it --image google/cloud-sdk:slim \
  --namespace $NAMESPACE workload-identity-test\
  -- gcloud auth list

If you don't see a command prompt, try pressing Enter.

If the steps were correctly run, you should see a response like the following:

                   Credentialed Accounts
ACTIVE  ACCOUNT
*       GSA@PROJECT_ID.iam.gserviceaccount.com

If upgrading from a previous install, clean up secrets that contained service account private keys:

kubectl delete secrets -n $NAMESPACE $(k get secrets -n $NAMESPACE | grep svc-account | awk '{print $1}')

Check logs:

kubectl logs -n $NAMESPACE -l app=apigee=synchronizer,env=$ENV_NAME,org=$ORG_NAME apigee-synchronizer
