OADP-6675: Add Azure workload identity support for image registry by kaovilai · Pull Request #1952 · openshift/oadp-operator

kaovilai · 2025-09-09T21:57:07Z

Why the changes were made

This PR adds Azure workload identity support for the image registry component, enabling Azure AD authentication when using workload identity federation. This is required to support image backup/restore operations in Azure environments using workload identity instead of service principal credentials.

Related to standardized STS authentication workflow for Azure.

How to test the changes made

Prerequisites

OpenShift cluster with OIDC enabled
Azure CLI installed and logged in
OADP operator built from this branch

Setup Azure Workload Identity

Set environment variables:

export API_URL=$(oc whoami --show-server)
export CLUSTER_NAME=$(echo "$API_URL" | sed 's|https://api\.||' | sed 's|\..*||')
export CLUSTER_RESOURCE_GROUP="${CLUSTER_NAME}-rg"
export AZURE_SUBSCRIPTION_ID=$(az account show --query id -o tsv)
export AZURE_TENANT_ID=$(az account show --query tenantId -o tsv)
export IDENTITY_NAME="velero"
export APP_NAME="velero-${CLUSTER_NAME}"
export STORAGE_ACCOUNT_NAME=$(echo "velero${CLUSTER_NAME}" | tr -d '-' | tr '[:upper:]' '[:lower:]' | cut -c1-24)
export CONTAINER_NAME="velero"

Follow Azure workload identity setup from oadp-azure-sts-cloud-authentication.adoc
Install OADP operator with Azure workload identity:

# Get the Azure managed identity client ID from previous setup
export AZURE_CLIENT_ID=<your-managed-identity-client-id>

# Deploy OADP with Azure workload identity
make deploy-olm-stsflow-azure \
  AZURE_CLIENT_ID=${AZURE_CLIENT_ID} \
  AZURE_TENANT_ID=${AZURE_TENANT_ID} \
  AZURE_SUBSCRIPTION_ID=${AZURE_SUBSCRIPTION_ID}

# Create deployment using the built image
oc new-app test-app -n test-images

# Verify the image is in internal registry
oc get imagestream test-app -n test-images -o yaml

Verify workload identity is detected:

# Check operator logs for "Azure workload identity detected"
oc logs -n openshift-adp deployment/oadp-operator-controller-manager -c manager | grep -i "workload identity"

# Verify secret created with correct credentials_type
oc get secret -n openshift-adp oadp-<bsl-name>-azure-registry-secret -o yaml | grep credentials_type
# Should show: credentials_type: ZGVmYXVsdF9jcmVkZW50aWFscw== (base64 for "default_credentials")

# Verify Azure workload identity env vars are present in Velero
oc get deployment velero -n openshift-adp -o yaml | grep -A5 envFrom
# Should show reference to azure-workload-identity-env secret

# Verify the secret contains required env vars
oc get secret -n openshift-adp azure-workload-identity-env -o yaml
# Should contain: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_FEDERATED_TOKEN_FILE

Test backup and restore with internal registry images:

# Create backup including the namespace with builds and images
velero backup create test-backup --include-namespaces test-images

# Monitor backup progress
velero backup describe test-backup --details

# Verify registry operations in logs
oc logs -n openshift-adp -l component=registry

# Delete the test namespace
oc delete project test-images

# Restore from backup
velero restore create --from-backup test-backup

# Verify restored resources
oc get all -n test-images
oc get imagestream test-app -n test-images
oc get pods -n test-images

# Verify the restored app is running with image from internal registry
oc describe pod -n test-images -l app=test-app | grep Image

Verification Points

AzureIsWorkloadIdentity() returns true when env vars are set
Registry secret contains credentials_type: default_credentials
Velero deployment has envFrom reference to azure-workload-identity-env secret
Azure workload identity environment variables are injected into Velero pod
No SPN environment variables in registry pod
BuildConfig images are backed up from internal registry
ImageStreams are properly restored
Deployed applications using internal registry images work after restore
Registry authenticates using workload identity (check registry pod logs)

Technical Details

Azure Workload Identity Authentication Flow

When Azure workload identity is detected (via the AzureIsWorkloadIdentity() function), the operator:

Creates a secret (azure-workload-identity-env) containing:
- AZURE_CLIENT_ID: The managed identity client ID
- AZURE_TENANT_ID: The Azure tenant ID
- AZURE_FEDERATED_TOKEN_FILE: Set to /var/run/secrets/openshift/serviceaccount/token

Injects the secret into Velero (see internal/controller/velero.go:642-655):

if stsflow.AzureIsWorkloadIdentity() {
    // Use envFrom to reference the secret containing Azure workload identity env vars
    veleroContainer.EnvFrom = append(veleroContainer.EnvFrom, corev1.EnvFromSource{
        SecretRef: &corev1.SecretEnvSource{
            LocalObjectReference: corev1.LocalObjectReference{
                Name: stsflow.AzureWorkloadIdentitySecretName,
            },
        },
    })
}

Azure SDK authentication: The Azure SDK's DefaultAzureCredential automatically:
- Detects these environment variables in the Velero container
- Reads the federated token from the path specified in AZURE_FEDERATED_TOKEN_FILE
- Exchanges it for Azure AD tokens using the federated identity
- Authenticates to Azure services transparently

This design ensures that both Velero and the registry components have the necessary environment variables for workload identity authentication, while the Azure SDK handles the actual token exchange and authentication flow.

Changes Summary

Added AzureIsWorkloadIdentity() helper function to detect Azure workload identity configuration
Created ReconcileAzureWorkloadIdentitySecret() to manage the workload identity secret
Inject Azure workload identity environment variables into Velero container via envFrom
Replaced deprecated SPN environment variables with new CREDENTIALS_* format matching docker-distribution expectations
Added support for default_credentials authentication type when workload identity is detected
Refactored repeated workload identity detection pattern into a reusable function
Removed legacy SPN environment variable constants

Dependencies

This PR requires corresponding changes in the openshift-velero-plugin repository to consume the new secret format.

Summary by CodeRabbit

New Features
- Azure registry configuration now supports workload identity, shared-key, and client-secret credential modes, with the selected mode recorded in registry credentials.
- Azure workload identity is recognized consistently across node agents, Velero, and secret management when the required identity settings are present.
Bug Fixes
- Improved handling of incomplete Azure identity settings so workload identity is not activated unless all required values are configured.

Additional Testing: Service Principal Credentials (Backward Compatibility)

To ensure backward compatibility with existing Service Principal authentication, please also test with traditional Azure credentials:

Test with Service Principal

Create Service Principal credentials:

# Create service principal
az ad sp create-for-rbac \
  --name "velero-sp-${CLUSTER_NAME}" \
  --role "Storage Blob Data Contributor" \
  --scopes "/subscriptions/${AZURE_SUBSCRIPTION_ID}/resourceGroups/${CLUSTER_RESOURCE_GROUP}/providers/Microsoft.Storage/storageAccounts/${STORAGE_ACCOUNT_NAME}"

# Save the output values:
# - appId (client_id)
# - password (client_secret)
# - tenant (tenant_id)

Create credentials secret:

cat <<EOF > /tmp/credentials-velero
AZURE_SUBSCRIPTION_ID=${AZURE_SUBSCRIPTION_ID}
AZURE_TENANT_ID=<tenant-from-sp-output>
AZURE_CLIENT_ID=<appId-from-sp-output>
AZURE_CLIENT_SECRET=<password-from-sp-output>
AZURE_RESOURCE_GROUP=${CLUSTER_RESOURCE_GROUP}
AZURE_STORAGE_ACCOUNT_ID=${STORAGE_ACCOUNT_NAME}
AZURE_CLOUD_NAME=AzurePublicCloud
EOF

oc create secret generic cloud-credentials-azure \
  -n openshift-adp \
  --from-file=cloud=/tmp/credentials-velero

Deploy OADP operator WITHOUT workload identity env vars:

# Deploy using standard OLM without STS flow
make deploy-olm

Create DPA with Service Principal:

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: dpa-sp
  namespace: openshift-adp
spec:
  backupLocations:
    - velero:
        provider: azure
        config:
          storageAccount: ${STORAGE_ACCOUNT_NAME}
          resourceGroup: ${CLUSTER_RESOURCE_GROUP}
        credential:
          name: cloud-credentials-azure
          key: cloud
        objectStorage:
          bucket: ${CONTAINER_NAME}

Verify Service Principal authentication:

# Check registry secret has client_secret credentials_type
oc get secret -n openshift-adp oadp-dpa-sp-azure-registry-secret -o yaml | grep credentials_type
# Should show: credentials_type: Y2xpZW50X3NlY3JldA== (base64 for "client_secret")

# Verify NO azure-workload-identity-env secret is created
oc get secret -n openshift-adp azure-workload-identity-env 2>&1 | grep "NotFound"

# Test backup/restore with SP credentials
velero backup create sp-test-backup --include-namespaces test-images

Verification for Backward Compatibility

Service Principal credentials continue to work
Registry secret contains credentials_type: client_secret for SP
No workload identity secret created when env vars not present
Image backup/restore works with SP authentication
Existing DPAs with SP credentials are not affected by upgrade

Verification Points

AzureIsWorkloadIdentity() returns true when env vars are set

Registry secret contains credentials_type: default_credentials

Velero deployment has envFrom reference to azure-workload-identity-env secret

Azure workload identity environment variables are injected into Velero pod

No SPN environment variables in registry pod

BuildConfig images are backed up from internal registry

ImageStreams are properly restored

Deployed applications using internal registry images work after restore

Registry authenticates using workload identity (check registry pod logs)

Technical Details

Azure Workload Identity Authentication Flow

When Azure workload identity is detected (via the AzureIsWorkloadIdentity() function), the operator:

Creates a secret (azure-workload-identity-env) containing:

AZURE_CLIENT_ID: The managed identity client ID

AZURE_TENANT_ID: The Azure tenant ID

AZURE_FEDERATED_TOKEN_FILE: Set to /var/run/secrets/openshift/serviceaccount/token

Injects the secret into Velero (see internal/controller/velero.go:642-655):
if stsflow.AzureIsWorkloadIdentity() {
    // Use envFrom to reference the secret containing Azure workload identity env vars
    veleroContainer.EnvFrom = append(veleroContainer.EnvFrom, corev1.EnvFromSource{
        SecretRef: &corev1.SecretEnvSource{
            LocalObjectReference: corev1.LocalObjectReference{
                Name: stsflow.AzureWorkloadIdentitySecretName,
            },
        },
    })
}
Azure SDK authentication: The Azure SDK's DefaultAzureCredential automatically:

Detects these environment variables in the Velero container

Reads the federated token from the path specified in AZURE_FEDERATED_TOKEN_FILE

Exchanges it for Azure AD tokens using the federated identity

Authenticates to Azure services transparently

This design ensures that both Velero and the registry components have the necessary environment variables for workload identity authentication, while the Azure SDK handles the actual token exchange and authentication flow.

Changes Summary

Added AzureIsWorkloadIdentity() helper function to detect Azure workload identity configuration

Created ReconcileAzureWorkloadIdentitySecret() to manage the workload identity secret

Inject Azure workload identity environment variables into Velero container via envFrom

Replaced deprecated SPN environment variables with new CREDENTIALS_* format matching docker-distribution expectations

Added support for default_credentials authentication type when workload identity is detected

Refactored repeated workload identity detection pattern into a reusable function

Removed legacy SPN environment variable constants

Dependencies

This PR requires corresponding changes in the openshift-velero-plugin repository to consume the new secret format.

Walkthrough

Azure workload identity detection now uses one helper across controller paths. Azure registry secret population selects a credentials type based on workload identity, storage account key, or client credentials. Tests cover the registry credential cases.

Changes

Azure credentials

Layer / File(s)	Summary
Workload identity detection `pkg/credentials/stsflow/stsflow.go`	Adds `AzureIsWorkloadIdentity`, which returns true when the client ID, tenant ID, and subscription ID environment variables are non-empty.
Workload identity wiring `internal/controller/stsflow.go`, `internal/controller/nodeagent.go`, `internal/controller/velero.go`	Uses the helper to gate secret reconciliation and select Azure workload identity Secret injection for node-agent and Velero containers.
Azure registry credentials `internal/controller/registry.go`, `internal/controller/registry_test.go`	Updates Azure registry environment-variable keys and selects `default_credentials`, `shared_key`, or `client_secret`. Tests cover these modes and incomplete workload identity variables.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Suggested reviewers: joeavaikath

Merge Risk: 🟡 Moderate · up to 2d67f

On Azure clusters that use workload identity, image backup and restore can fail in two ways. Workload identity overrides a storage key configured on a backup location. In addition, the currently published plugin does not understand the new credentials format. Before merging, give explicit backup-location credentials precedence and coordinate this change with the matching plugin release.

Ship a plugin that consumes the new Azure credentials contract.

The default image remains quay.io/konveyor/openshift-velero-plugin:latest. The oadp-dev plugin source still maps client_id_key, client_secret_key, and tenant_id_key to REGISTRY_STORAGE_AZURE_SPN_* variables. It does not consume credentials_type or emit REGISTRY_STORAGE_AZURE_CREDENTIALS_*. If the release image uses this implementation, it cannot select the new default_credentials mode for workload identity, so Azure image backup and restore may fail. Existing service-principal fields still pass through the old variable names.

Use a plugin image with the matching consumer change, or preserve the old contract until both changes ship.

Note

Responses generated with Hermes Agent

Fixed the credential-precedence CodeRabbit finding: populateAzureRegistrySecret now selects shared_key (or leaves it to the existing per-value validation) whenever the BSL specifies storageAccountKeyEnvVar, before falling back to default_credentials for workload identity. Pushed as 9957cae.

The other CodeRabbit thread (plugin-image contract mismatch for REGISTRY_STORAGE_AZURE_CREDENTIALS_*) is a cross-repo coordination/design issue (needs a corresponding openshift-velero-plugin change), not a mechanical fix here — left open for you to decide (ship matching plugin image vs. preserve old contract until both land).
