Wallaroo MLOps API Essentials Guide: Pipeline Edge Publishing Management

How to use the Wallaroo API for Pipeline Edge Publishing Management

Wallaroo pipelines can be published to a Edge Open Container Initiative (OCI) Registry Service, known here as the Edge Registry Service, as a container images. This allows the Wallaroo pipelines to be deployed in other environments, such as Docker or Kubernetes with all of the pipeline model. When deployed, these pipelines can perform inferences from the ML models exactly as if they were deployed as part of a Wallaroo instance.

When a pipeline is updated with new model steps or deployment configurations, the updated pipeline is republished to the Edge Registry as a new repo and version. This allows DevOps engineers to update an Wallaroo pipeline in any container supporting environment with the new versions of the pipeline.

Pipeline Publishing Flow

A typical ML Model and Pipeline deployment to Wallaroo Ops and to remote locations as a Wallaroo Inference server is as follows:

Components:
- Wallaroo Ops: The Wallaroo Ops provides the backbone services for ML Model deployment. This is where ML models are uploaded, pipelines created and deployed for inferencing, pipelines published to OCI compliant registries, and other functions.
- Wallaroo Inference Server: A remote deployment of a published Wallaroo pipeline with the Wallaroo Inference Engine outside the Wallaroo Ops instance. When the edge name is added to a Wallaroo publish, the Wallaroo Inference Server’s inference logs are submitted to the Wallaroo Ops instance. These inference logs are stored as part of the Wallaroo pipeline the remote deployment is published from.

DevOps:
1. Add Edge Publishing and Edge Observability to the Wallaroo Ops center. See Edge Deployment Registry Guide for details on updating the Wallaroo instance with Edge Publishing and Edge Observability.
Data Scientists:
1. Develop and train models.
2. Test their deployments in Wallaroo Ops Center as Pipelines with:
  1. Pipeline Steps: The models part of the inference flow.
  2. Pipeline Deployment Configurations: CPUs, RAM, GPU, and Architecture settings to run the pipeline.
3. Publish the Pipeline from the Wallaroo Ops to an OCI Registry: Store a image version of the Pipeline with models and pipeline configuration into the OCI Registry set by the DevOps engineers as the Wallaroo Edge Registry Service.
DevOps:
1. Retrieve the new or updated Wallaroo published pipeline from the Wallaroo Edge Registry Service.
2. (Optional): Add an edge to the Wallaroo publish. This provides the EDGE_BUNDLE with the credentials for the Wallaroo Inference Server to transmit its inference result logs back to the Wallaroo Ops instance. These inference logs are added to the originating Wallaroo pipeline, labeled with the metadata.partition being the name of the edge deployed Wallaroo Inference server. For more details, see Wallaroo SDK Essentials Guide: Pipeline Edge Publication: Edge Observability
3. Deploy the Pipeline as a Wallaroo Inference Server as a Docker or Kubernetes container, updating the resource allocations as part of the Helm chart, Docker Compose file, etc.

Enable Wallaroo Edge Registry

Set Edge Registry Service

Wallaroo Pipeline Publishes aka Wallaroo Servers are automatically routed to the Edge Open Container Initiative (OCI) Registry Service registered in the Wallaroo instance. This is enabled through either the Kots Administrative Dashboard through kots, or by enabling it through a helm chart setting. From here on out, we will refer to it as the Edge Registry Service.

Set Edge Registry Service through Kots

To set the Edge Registry Settings through the Kots Administrative Dashboard:

Launch the Kots Administrative Dashboard using the following command, replacing the --namespace parameter with the Kubernetes namespace for the Wallaroo instance:
```
kubectl kots admin-console --namespace wallaroo
```
Open a browser at the URL detailed in the step above and authenticate using the console password set as described in the as detailed in the Wallaroo Install Guides.
From the top menu, select Config then scroll to Edge Deployment.
Enable Provide OCI registry credentials for pipelines.
Enter the following:
1. Registry URL: The address of the registry service. For example: us-west1-docker.pkg.dev.
2. email: The email address of the user account used to authenticate to the service.
3. username: The account used to authenticate to the registry service.
4. password: The password or token used to authenticate to the registry service.
Save the updated configuration, then deploy it. Once complete, the edge registry settings will be available.

Set Edge Registry Service through Helm

The helm settings for adding the Edge Server configuration details are set through the ociRegistry element, with the following settings.

ociRegistry: Sets the Edge Server registry information.
- enabled: true enables the Edge Server registry information, false disables it.
- registry: The registry url. For example: reg.big.corp:3579.
- repository: The repository within the registry. This may include the cloud account, or the full path where the Wallaroo published pipelines should be kept. For example: account123/wallaroo/pipelines.
- email: Optional field to track the email address of the registry credential.
- username: The username to the registry. This may vary based on the provider. For example, GCP Artifact Registry with service accounts uses the username _json_key_base64 with the password as a base64 processed token of the credential information.
- password: The password or token for the registry service.

Set Edge Observability Service

Edge Observability allows published Wallaroo Servers to community with the Wallaroo Ops center to update their associated Wallaroo Pipeline with inference results, visible in the Pipeline logs.

This process will create a new Kubernetes service edge-lb. Based on the configuration options below, the service will require an additional IP address separate from the Wallaroo service api-lb. The edge-lb will require a DNS hostname.

Set Edge Observability Service through Kots

To enable Edge Observability using the Kots Administrative Dashboard for kots installed instances of Wallaroo Ops:

Launch the Kots Administrative Dashboard using the following command, replacing the --namespace parameter with the Kubernetes namespace for the Wallaroo instance:
```
kubectl kots admin-console --namespace wallaroo
```
Open a browser at the URL detailed in the step above and authenticate using the console password set as described in the as detailed in the Wallaroo Install Guides.
Access Config and scroll to Edge Deployment and enable Enable pipelines deployed on the edge to send data back to the OpsCenter.
Set the following:
1. Specify the OpsCenter hostname or IP address, as reachable from edge sites.: Set the DNS address in the format https://service.{suffix domain}. For example, if the domain suffix is wallaroo.example.com and the Wallaroo Edge Observability Service is set to the hostname edge, then the URL to access the edge service is:
```
edge.wallaroo.example.com
```
2. Edge ingress mode: Set one of the following.
  1. None - Services are cluster local and kubernetes port forwarding must be used for access.
  2. Internal - Private network users can connect directly and do not need to port forward anything.
  3. External - Internet facing users can connect directly to interactive Wallaroo services. Exercise caution.
Save the updated configuration, then deploy it. Once complete, the edge observability service is available.
Set the DNS Hostname as described in the steps Set Edge Observability Service DNS Hostname.

Set Edge Observability Service through Helm

To enable the Edge Observability Service for Wallaroo Ops Helm based installation, include the following variables for the helm settings. For these instructions they are stored in local-values.yaml:

edgelb:
    serviceType: LoadBalancer
    enabled: true
    opscenterHost: mitch4.edge.wallaroocommunity.ninja

pipelines:
    enabled: true

Update the Wallaroo Helm installation with the same version as the Wallaroo ops and the channel. For example, if updating Wallaroo Enterprise server, use the following:

helm upgrade wallaroo oci://registry.replicated.com/wallaroo/2024-1/wallaroo --version 2024.1.0-5097 --values local-values.yaml

This process will take 5-15 minutes depending on other configuration options. Once complete, set the DNS address as described in Set Edge Observability Service DNS Hostname.

Set Edge Observability Service DNS Hostname

Once enabled, the Wallaroo Edge Observability Service requires a DNS address. The following instructions are specified for Edge ingress mode:External.

Obtain the external IP address of the the Wallaroo Edge Observability Service with the following command, replacing the -n wallaroo namespace option with the one the Wallaroo Ops instance is installed into.
```
EDGE_LOADBALANCER=$(kubectl get svc edge-lb -n wallaroo -o jsonpath='{.status.loadBalancer.ingress[0].ip}') && echo $EDGE_LOADBALANCER
```
Set the DNS address to the hostname set in the step Set Edge Observability Service through Kots if using kots to install, or Set Edge Observability Service through Helm if using helm.

Registry Setup Guides

The following are short guides for setting up the credentials for different registry services. Refer to the registry documentation for full details.

The following process is used with a GitHub Container Registry to create the authentication tokens for use with a Wallaroo instance’s Private Model Registry configuration.

See the GitHub Working with the Container registry for full details.

The following process is used register a GitHub Container Registry with Wallaroo.

Create a new token as per the instructions from the Creating a personal access token (classic) guide. Note that a classic token is recommended for this process. Store this token in a secure location as it will not be able to be retrieved later from GitHub. Verify the following permissions are set:
1. Select the write:packages scope to download and upload container images and read and write their metadata.
2. Select the read:packages scope to download container images and read their metadata (selected when write:packages is selected by default).
3. Select the delete:packages scope to delete container images.
Store the token in a secure location.

This can be tested with docker by logging into the specified registry. For example:

docker login -u {Github Username} --password {Your Token} ghcr.io/{Your Github Username or Organization}

The following process is an example of setting up an Artifact Registry Service with Google Cloud Platform (GCP) that is used to store containerized model images and retrieve them for use with Wallaroo.

Uploading and downloading containerized models to a Google Cloud Platform Registry follows these general steps.

Create the GCP registry.
Create a Service Account that will manage the registry service requests.
Assign appropriate Artifact Registry role to the Service Account
Retrieve the Service Account credentials.
Using either a specific user, or the Service Account credentials, upload the containerized model to the registry service.
Add the service account credentials to the Wallaroo instance’s containerized model private registry configuration.
Prerequisites

The commands below use the Google gcloud command line tool, and expect that a Google Cloud Platform account is created and the gcloud application is associated with the GCP Project for the organization.

For full details on the process and other methods, see the Google GCP documentation.

Create the Registry

The following is based on the Create a repository using the Google Cloud CLI.

The following information is needed up front:

$REPOSITORY_NAME: What to call the registry.
$LOCATION: Where the repository will be located. GCP locations are derived through the gcloud artifacts locations list command.
$DESCRIPTION: Any details to be displayed. Sensitive data should not be included.

The follow example script will create a GCP registry with the minimum requirements.

REPOSITORY_NAME="YOUR NAME"
LOCATION="us-west1"
DESCRIPTION="My amazing registry."

gcloud artifacts repositories create REPOSITORY \
    --repository-format=docker \
    --location=LOCATION \
    --description="$DESCRIPTION" \
    --async

Create a GCP Registry Service Account

The GCP Registry Service Account is used to manage the GCP registry service. The steps are details from the Google Create a service account guide.

The gcloud process for these steps are:

Connect the gcloud application to the organization’s project.

$PROJECT_ID="YOUR PROJECT ID"
gcloud config set project $PROJECT_ID

Create the service account with the following:

The name of the service account.
A description of its purpose.
The name to show when displayed.

SA_NAME="YOUR SERVICE ACCOUNT NAME"
DESCRIPTION="Wallaroo container registry SA"
DISPLAY_NAME="Wallaroo the Roo"

gcloud iam service-accounts create $SA_NAME \
--description=$DESCRIPTION \
--display-name=$DISPLAY_NAME

Assign Artifact Registry Role

Assign one or more of the following accounts to the new registry role based on the following criteria, as detailed in the Google GCP Repository Roles and Permissions Guide.

For pkg.dev domains.

Role	Description
Artifact Registry Reader (roles/artifactregistry.reader)	View and get artifacts, view repository metadata.
Artifact Registry Writer (roles/artifactregistry.writer)	Read and write artifacts.
Artifact Registry Repository Administrator (roles/artifactregistry.repoAdmin)	Read, write, and delete artifacts.
Artifact Registry Administrator (roles/artifactregistry.admin)	Create and manage repositories and artifacts.

For gcr.io repositories.

Role	Description
Artifact Registry Create-on-push Writer (roles/artifactregistry.createOnPushWriter)	Read and write artifacts. Create gcr.io repositories.
Artifact Registry Create-on-push Repository Administrator (roles/artifactregistry.createOnPushRepoAdmin)	Read, write, and delete artifacts. Create gcr.io repositories.

For this example, we will add the Artifact Registry Create-on-push Writer to the created Service Account from the previous step.

Add the role to the service account, specifying the member as the new service account, and the role as the selected role. For this example, a pkg.dev is assumed for the Artifact Registry type.


# for pkg.dev
ROLE="roles/artifactregistry.writer"

# for gcr.io 
#ROLE="roles/artifactregistry.createOnPushWriter

gcloud projects add-iam-policy-binding \
    $PROJECT_ID \
    --member="serviceAccount:$SA_NAME@$PROJECT_ID.iam.gserviceaccount.com" \
    --role=$ROLE

Authenticate to Repository

To push and pull image from the new registry, we’ll use our new service account and authenticate through the local Docker application. See the GCP Push and pull images for details on using Docker and other methods to add artifacts to the GCP artifact registry.

Set up Service Account Key

To set up the Service Account key, we’ll use the Google Console IAM & ADMIN dashboard based on the Set up authentication for Docker, using the JSON key approach.

From GCP console, search for IAM & Admin.
Select Service Accounts.
Select the service account to generate keys for.
Select the Email address listed and store this for later steps with the key generated through this process.
Select Keys, then Add Key, then Create new key.
Select JSON, then Create.
Store the key in a safe location.

Convert SA Key to Base64

The key file downloaded in Set up Service Account Key needs to be converted to base64 with the following command, replacing the locations of KEY_FILE and KEYFILEBASE64:

KEY_FILE = ~/.gcp-sa-registry-keyfile.json
KEYFILEBASE64 = ~/.gcp-sa-registry-keyfile-b64.json
base64 -i $KEY_FILE -o $KEYFILEBASE64

This base64 key is then used as the authentication token, with the username _json_key_base64.

This can be tested with docker by logging into the specified registry. For example:

token=$(cat $KEYFILEBASE64)
cat $tok | docker login -u _json_key_base64 --password-stdin https://{GCP artifact registry region}.pkg.dev

Edge Observability

Edge Observability allows edge deployments of Wallaroo Server to transmit inference results back to the Wallaroo Ops center and become part of the pipeline’s logs. This is valuable for data scientists and MLOps engineers to retrieve edge deployment logs for use in model observability, drift, and other use cases.

Before starting, the Edge Observability Service must be enabled in the Wallaroo Ops center. See the Edge Deployment Registry Guide for details on enabling the Wallaroo Edge Deployment service.

Wallaroo Server edge observability is enabled when a new edge location is added to the pipeline publish. Each location has its own EDGE_BUNDLE settings, a Base64 encoded set of instructions informing the edge deployed Wallaroo Server on how to communicate with Wallaroo Ops center.

Edge Bundle Token TTL

When an edge is added to a pipeline publish, the field docker_run_variables contains a JSON value for edge devices to connect to the Wallaroo Ops instance. The settings are stored in the key EDGE_BUNDLE as a base64 encoded value that include the following:

BUNDLE_VERSION: The current version of the bundled Wallaroo pipeline.
EDGE_NAME: The edge name as defined when created and added to the pipeline publish.
JOIN_TOKEN_: The one time authentication token for authenticating to the Wallaroo Ops instance.
OPSCENTER_HOST: The hostname of the Wallaroo Ops edge service. See Edge Deployment Registry Guide for full details on enabling pipeline publishing and edge observability to Wallaroo.
PIPELINE_URL
WORKSPACE_ID.

For example:

{'edgeBundle': 'ZXhwb3J0IEJVTkRMRV9WRVJTSU9OPTEKZXhwb3J0IEVER0VfTkFNRT14Z2ItY2NmcmF1ZC1lZGdlLXRlc3QKZXhwb3J0IEpPSU5fVE9LRU49MzE0OGFkYTUtMjg1YS00ZmNhLWIzYjgtYjUwYTQ4ZDc1MTFiCmV4cG9ydCBPUFNDRU5URVJfSE9TVD1kb2MtdGVzdC5lZGdlLndhbGxhcm9vY29tbXVuaXR5Lm5pbmphCmV4cG9ydCBQSVBFTElORV9VUkw9Z2hjci5pby93YWxsYXJvb2xhYnMvZG9jLXNhbXBsZXMvcGlwZWxpbmVzL2VkZ2UtcGlwZWxpbmU6ZjM4OGMxMDktOGQ1Ny00ZWQyLTk4MDYtYWExM2Y4NTQ1NzZiCmV4cG9ydCBXT1JLU1BBQ0VfSUQ9NQ=='}

export WORKSPACE_ID=5

The JOIN_TOKEN is a one time access token. Once used, a JOIN_TOKEN expires. The authentication session data is stored in persistent volumes. Persistent volumes must be specified for docker and docker compose based deployments of Wallaroo pipelines; helm based deployments automatically provide persistent volumes to store authentication credentials.

The JOIN_TOKEN has the following time to live (TTL) parameters.

Once created, the JOIN_TOKEN is valid for 24 hours. After it expires the edge will not be allowed to contact the OpsCenter the first time and a new edge bundle will have to be created.
After an Edge joins to Wallaroo Ops for the first time with persistent storage, the edge must contact the Wallaroo Ops instance at least once every 7 days.
- If this period is exceeded, the authentication credentials will expire and a new edge bundle must be created with a new and valid JOIN_TOKEN.

Wallaroo edges require unique names. To create a new edge bundle with the same name:

Use the Remove Edge to remove the edge by name.
Use Add Edge to add the edge with the same name. A new EDGE_BUNDLE is generated with a new JOIN_TOKEN.

DevOps - Pipeline Edge Deployment

Once a pipeline is deployed to the Edge Registry service, it can be deployed in environments such as Docker, Kubernetes, or similar container running services by a DevOps engineer.

Docker Deployment

First, the DevOps engineer must authenticate to the same OCI Registry service used for the Wallaroo Edge Deployment registry.

For more details, check with the documentation on your artifact service. The following are provided for the three major cloud services:

For the deployment, the engine URL is specified with the following environmental variables:

DEBUG (true|false): Whether to include debug output.
OCI_REGISTRY: The URL of the registry service.
CONFIG_CPUS: The number of CPUs to use.
OCI_USERNAME: The edge registry username.
OCI_PASSWORD: The edge registry password or token.
PIPELINE_URL: The published pipeline URL.
EDGE_BUNDLE (Optional): The base64 encoded edge token and other values to connect to the Wallaroo Ops instance. This is used for edge management and transmitting inference results for observability. IMPORTANT NOTE: The token for EDGE_BUNDLE is valid for one deployment. For subsequent deployments, generate a new edge location with its own EDGE_BUNDLE.
LOCAL_INFERENCE_STORAGE (Optional): Sets amount of storage to allocate for the edge deployments inference log storage capacity. This is in the format {size as number}{unit value}. The values are similar to the Kubernetes memory resource units format. If used, must be used with PLATEAU_PAGE_SIZE. The accepted unit values are:
- Ki (for KiloBytes)
- Mi (for MegaBytes)
- Gi (for GigaBytes)
- Ti (for TeraBytes)
PLATEAU_PAGE_SIZE (Optional): How many inference log rows to upload from the edge deployment at a time. Must be used with LOCAL_INFERENCE_STORAGE.

Docker Deployment Example

Using our sample environment, here’s sample deployment using Docker with a computer vision ML model, the same used in the Wallaroo Use Case Tutorials Computer Vision: Retail tutorials.

Login through docker to confirm access to the registry service. First, docker login. For example, logging into the artifact registry with the token stored in the variable tok:
```
cat $tok | docker login -u _json_key_base64 --password-stdin https://sample-registry.com
```

Then deploy the Wallaroo published pipeline with an edge added to the pipeline publish through docker run.

IMPORTANT NOTE: Edge deployments with Edge Observability enabled with the EDGE_BUNDLE option include an authentication token that only authenticates once. To store the token long term, include the persistent volume flag -v {path to storage} setting.

Deployment with EDGE_BUNDLE for observability.

ghcr.io/wallaroolabs/doc-samples/engines/proxy/wallaroo/ghcr.io/wallaroolabs/standalone-mini:v2023.4.0-main-4079

Connection to the Wallaroo Ops instance from edge deployment with EDGE_BUNDLE is verified with the long entry Node attestation was successful.

Deployment without observability.

docker run -p 8080:8080 \
-e DEBUG=true \
-e OCI_REGISTRY=$REGISTRYURL \
-e CONFIG_CPUS=1 \
-e OCI_USERNAME=$REGISTRYUSERNAME \
-e OCI_PASSWORD=$REGISTRYPASSWORD \

ghcr.io/wallaroolabs/doc-samples/engines/proxy/wallaroo/ghcr.io/wallaroolabs/standalo

Docker Compose Deployment

For users who prefer to use docker compose, the following sample compose.yaml file is used to launch the Wallaroo Edge pipeline. This is the same used in the Wallaroo Use Case Tutorials Computer Vision: Retail tutorials. The volumes tag is used to preserve the login session from the one-time token generated as part of the EDGE_BUNDLE.

EDGE_BUNDLE is only required when adding an edge to a Wallaroo publish for observability. The following is deployed without observability.

services:
  engine:
    image: {Your Engine URL}
    ports:
      - 8080:8080
    environment:
      PIPELINE_URL: {Your Pipeline URL}
      OCI_REGISTRY: {Your Edge Registry URL}
      OCI_USERNAME:  {Your Registry Username}
      OCI_PASSWORD: {Your Token or Password}
      CONFIG_CPUS: 4

The procedure is:

Login through docker to confirm access to the registry service. First, docker login. For example, logging into the artifact registry with the token stored in the variable tok to the registry us-west1-docker.pkg.dev:
```
cat $tok | docker login -u _json_key_base64 --password-stdin https://sample-registry.com
```

Set up the compose.yaml file.

services:
engine:
    image: sample-registry.com/engine:v2023.3.0-main-3707
    ports:
        - 8080:8080
    volumes:
        - ./data:/persist
environment:

    OCI_REGISTRY: sample-registry.com
    OCI_USERNAME:  _json_key_base64
    OCI_PASSWORD: abc123
    CONFIG_CPUS: 4

Then deploy with docker compose up.

Docker Compose Deployment Example

The deployment and undeployment is then just a simple docker compose up and docker compose down. The following shows an example of deploying the Wallaroo edge pipeline using docker compose.

Helm Deployment

Published pipelines can be deployed through the use of helm charts.

Helm deployments take up to two steps - the first step is in retrieving the required values.yaml and making updates to override.

IMPORTANT NOTE: Edge deployments with Edge Observability enabled with the EDGE_BUNDLE option include an authentication token that only authenticates once. Helm chart installations automatically add a persistent volume during deployment to store the authentication session data for future deployments.

Login to the registry service with helm registry login. For example, if the token is stored in the variable tok:
```
helm registry login sample-registry.com --username _json_key_base64 --password $tok
```
Pull the helm charts from the published pipeline. The two fields are the Helm Chart URL and the Helm Chart version to specify the OCI . This typically takes the format of:
```
helm pull oci://{published.helm_chart_url} --version {published.helm_chart_version}
```

Extract the tgz file and copy the values.yaml and copy the values used to edit engine allocations, etc. The following are required for the deployment to run:

ociRegistry:
    registry: {your registry service}
    username:  {registry username here}
    password: {registry token here}

For Wallaroo Server deployments with edge location set, the values include edgeBundle as generated when the edge was added to the pipeline publish.

ociRegistry:
    registry: {your registry service}
    username:  {registry username here}
    password: {registry token here}
edgeBundle: abcdefg

Store this into another file, suc as local-values.yaml.

Create the namespace to deploy the pipeline to. For example, the namespace wallaroo-edge-pipeline would be:
```
kubectl create -n wallaroo-edge-pipeline
```

Deploy the helm installation with helm install through one of the following options:

Specify the tgz file that was downloaded and the local values file. For example:

helm install --namespace {namespace} --values {local values file} {helm install name} {tgz path}

Specify the expended directory from the downloaded tgz file.

helm install --namespace {namespace} --values {local values file} {helm install name} {helm directory path}

Specify the Helm Pipeline Helm Chart and the Pipeline Helm Version.

helm install --namespace {namespace} --values {local values file} {helm install name} oci://{published.helm_chart_url} --version {published.helm_chart_version}

Once deployed, the DevOps engineer will have to forward the appropriate ports to the svc/engine-svc service in the specific pipeline. For example, using kubectl port-forward to the namespace ccfraud that would be:
```
kubectl port-forward svc/engine-svc -n ccfraud01 8080 --address 0.0.0.0`
```
