Procedure

1. Create an AWS S3 bucket.

2. Create the following trust.json file for the AWS Identity and Access Management (AWS IAM) policy for the purpose of setting up a trust relationship between the AWS IAM role, which you will create in the next step, and the service account of either the TempoStack or TempoMonolithic instance:

   trust.json

   {
       "Version": "2012-10-17",
       "Statement": [
         {
           "Effect": "Allow",
           "Principal": {
             "Federated": "arn:aws:iam::<aws_account_id>:oidc-provider/<oidc_provider>" 

   1

   
           },
           "Action": "sts:AssumeRoleWithWebIdentity",
           "Condition": {
             "StringEquals": {
               "<oidc_provider>:sub": [
                 "system:serviceaccount:<openshift_project_for_tempo>:tempo-<tempo_custom_resource_name>" 

   2

              ]
            }
          }
        }
       ]
   }

   Copy to Clipboard

   1

   The OpenID Connect (OIDC) provider that you have configured on the OpenShift Container Platform.

   2

   The namespace in which you intend to create either a TempoStack or TempoMonolithic instance. Replace <tempo_custom_resource_name> with the metadata name that you define in your TempoStack or TempoMonolithic custom resource.

   Tip

   You can also get the value for the OIDC provider by running the following command:

   $ oc get authentication cluster -o json | jq -r '.spec.serviceAccountIssuer' | sed 's~http[s]*://~~g'

   Copy to Clipboard

3. Create an AWS IAM role by attaching the created trust.json policy file. You can do this by running the following command:

   $ aws iam create-role \
         --role-name "tempo-s3-access" \
         --assume-role-policy-document "file:///tmp/trust.json" \
         --query Role.Arn \
         --output text

   Copy to Clipboard

4. Attach an AWS IAM policy to the created AWS IAM role. You can do this by running the following command:

   $ aws iam attach-role-policy \
         --role-name "tempo-s3-access" \
         --policy-arn "arn:aws:iam::aws:policy/AmazonS3FullAccess"

   Copy to Clipboard

5. If you are not using the CCO, skip this step. If you are using the CCO, configure the cloud provider environment for the Tempo Operator. You can do this by running the following command:

   $ oc patch subscription <tempo_operator_sub> \ 

   1

   
             -n <tempo_operator_namespace> \ 

   2

   
             --type='merge' -p '{"spec": {"config": {"env": [{"name": "ROLEARN", "value": "'"<role_arn>"'"}]}}}' 

   3

   Copy to Clipboard

   1

   The name of the Tempo Operator subscription.

   2

   The namespace of the Tempo Operator.

   3

   The AWS STS requires adding the ROLEARN environment variable to the Tempo Operator subcription. As the <role_arn> value, add the Amazon Resource Name (ARN) of the AWS IAM role that you created in step 3.

6. In the OpenShift Container Platform, create an object storage secret with keys as follows:

   apiVersion: v1
   kind: Secret
   metadata:
     name: <secret_name>
   stringData:
     bucket: <s3_bucket_name>
     region: <s3_region>
     role_arn: <s3_role_arn>
   type: Opaque

   Copy to Clipboard

7. When the object storage secret is created, update the relevant custom resource of the Distributed Tracing Platform instance as follows:

   Example TempoStack custom resource

   apiVersion: tempo.grafana.com/v1alpha1
   kind: TempoStack
   metadata:
     name: <name>
     namespace: <namespace>

   2

   
   # ...

   Copy to Clipboard

   1

   The secret that you created in the previous step.

   2

   If you are not using the CCO, omit this line. If you are using the CCO, add this parameter with the token-cco value.

   Example TempoMonolithic custom resource

   apiVersion: tempo.grafana.com/v1alpha1
   kind: TempoMonolithic
   metadata:

Procedure

1. Create a GCS bucket on the Google Cloud Platform (GCP).

2. Create or reuse a service account with Google’s Identity and Access Management (IAM):

   SERVICE_ACCOUNT_EMAIL=$(gcloud iam service-accounts create <iam_service_account_name> \ 

   1

   
       --display-name="Tempo Account" \
       --project <project_id>  \ 

   2

   
       --format='value(email)' \
       --quiet)

   Copy to Clipboard

   1

   The name of the service account on the GCP.

   2

   The project ID of the service account on the GCP.

3. Bind the required GCP roles to the created service account at the project level. You can do this by running the following command:

   $ gcloud projects add-iam-policy-binding <project_id> \
       --member "serviceAccount:$SERVICE_ACCOUNT_EMAIL" \
       --role "roles/storage.objectAdmin"

   Copy to Clipboard

4. Retrieve the POOL_ID value of the Google Cloud Workload Identity Pool that is associated with the cluster. How you can retrieve this value depends on your environment, so the following command is only an example:

   $ OIDC_ISSUER=$(oc get authentication.config cluster -o jsonpath='{.spec.serviceAccountIssuer}') \
   &&
     POOL_ID=$(echo "$OIDC_ISSUER" | awk -F'/' '{print $NF}' | sed 's/-oidc$//')

   Copy to Clipboard

5. Add the IAM policy bindings. You can do this by running the following commands:

   $ gcloud iam service-accounts add-iam-policy-binding "$SERVICE_ACCOUNT_EMAIL" \ 

   1

   
     --role="roles/iam.workloadIdentityUser" \
     --member="principal://iam.googleapis.com/projects/<project_number>/locations/global/workloadIdentityPools/<pool_id>/subject/system:serviceaccount:<tempo_namespace>:tempo-<tempo_name>" \
     --project=<project_id> \
     --quiet \
   &&
     gcloud iam service-accounts add-iam-policy-binding "$SERVICE_ACCOUNT_EMAIL" \
     --role="roles/iam.workloadIdentityUser" \
     --member="principal://iam.googleapis.com/projects/<project_number>/locations/global/workloadIdentityPools/<pool_id>/subject/system:serviceaccount:<tempo_namespace>:tempo-<tempo_name>-query-frontend" \
     --project=<project_id> \
     --quiet
   &&
     gcloud storage buckets add-iam-policy-binding "gs://$BUCKET_NAME" \
     --role="roles/storage.admin" \
     --member="serviceAccount:$SERVICE_ACCOUNT_EMAIL" \
     --condition=None

   Copy to Clipboard

   1

   The $SERVICE_ACCOUNT_EMAIL is the output of the command in step 2.

6. Create a credential file for the key.json key of the storage secret for use by the TempoStack custom resource. You can do this by running the following command:

   $ gcloud iam workload-identity-pools create-cred-config \
       "projects/<project_number>/locations/global/workloadIdentityPools/<pool_id>/providers/<provider_id>" \
       --service-account="$SERVICE_ACCOUNT_EMAIL" \
       --credential-source-file=/var/run/secrets/storage/serviceaccount/token \ 

   1

   
       --credential-source-type=text \
       --output-file=<output_file_path> 

   2

     --from-literal=bucketname="<bucket_name>" \ 

   1

   
     --from-literal=audience="<audience>" \      

   2

   
     --from-file=key.json=<output_file_path>

      1

      This CR creates a TempoMonolithic deployment with trace ingestion in the OTLP protocol.

      2

      The project that you have chosen for the TempoMonolithic deployment. Project names beginning with the openshift- prefix are not permitted.

      3

      Red Hat supports only the custom resource options that are available in the Red Hat OpenShift Distributed Tracing Platform documentation.

      4

      Specifies the storage for storing traces.

      5

      Type of storage for storing traces: in-memory storage, a persistent volume, or object storage. The value for a persistent volume is pv. The accepted values for object storage are s3, gcs, or azure, depending on the used object store type. The default value is memory for the tmpfs in-memory storage, which is only appropriate for development, testing, demonstrations, and proof-of-concept environments because the data does not persist when the pod is shut down.

      6

      Memory size: For in-memory storage, this means the size of the tmpfs volume, where the default is 2Gi. For a persistent volume, this means the size of the persistent volume claim, where the default is 10Gi. For object storage, this means the size of the persistent volume claim for the Tempo Write-Ahead Logging (WAL), where the default is 10Gi.

      7

      Optional: For object storage, the type of object storage. The accepted values are s3, gcs, and azure, depending on the used object store type.

      8

      Optional: For object storage, the value of the name in the metadata of the storage secret. The storage secret must be in the same namespace as the TempoMonolithic instance and contain the fields specified in "Table 1. Required secret parameters" in the section "Object storage setup".

      9

      Optional.

      10

      Optional: Name of a ConfigMap object that contains a CA certificate.

      11

      Exposes the Jaeger UI, which visualizes the data, via a route at http://<gateway_ingress>/api/traces/v1/<tenant_name>/search.

      12

      Enables creation of the route for the Jaeger UI.

      13

      Optional.

      14

      Lists the tenants.

      15

      The tenant name, which is used as the value for the X-Scope-OrgId HTTP header.

      16

      The unique identifier of the tenant. Must be unique throughout the lifecycle of the TempoMonolithic deployment. This ID will be added as a prefix to the objects in the object storage. You can reuse the value of the UUID or tempoName field.

   2. Apply the customized CR by running the following command:

      $ oc apply -f - << EOF
      <tempomonolithic_cr>
      EOF

Verification

1. Verify that the status of all TempoMonolithic components is Running and the conditions are type: Ready by running the following command:

   $ oc get tempomonolithic.tempo.grafana.com <metadata_name_of_tempomonolithic_cr> -o yaml

   Copy to Clipboard

2. Run the following command to verify that the pod of the TempoMonolithic instance is running:

   $ oc get pods

   Copy to Clipboard

3. Access the Jaeger UI:

   1. Query the route details for the tempo-<metadata_name_of_tempomonolithic_cr>-jaegerui route by running the following command:

      $ oc get route

      Copy to Clipboard
   2. Open https://<route_from_previous_step> in a web browser.

4. When the pod of the TempoMonolithic instance is ready, you can send traces to the tempo-<metadata_name_of_tempomonolithic_cr>:4317 (OTLP/gRPC) and tempo-<metadata_name_of_tempomonolithic_cr>:4318 (OTLP/HTTP) endpoints inside the cluster.

   The Tempo API is available at the tempo-<metadata_name_of_tempomonolithic_cr>:3200 endpoint inside the cluster.
