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.

1. 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.
2. 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.
3. 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 Wallaroo 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 Wallaroo Administrative Dashboard:

1. Launch the Wallaroo Administrative Dashboard using the following command, replacing the --namespace parameter with the Kubernetes namespace for the Wallaroo instance:

   kubectl kots admin-console --namespace wallaroo
   

2. 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.

3. From the top menu, select Config then scroll to Edge Deployment.

4. Enable Provide OCI registry credentials for pipelines.

5. 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.

6. 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 Wallaroo Administrative Dashboard for kots installed instances of Wallaroo Ops:

1. Launch the Wallaroo Administrative Dashboard using the following command, replacing the --namespace parameter with the Kubernetes namespace for the Wallaroo instance:

   kubectl kots admin-console --namespace wallaroo
   

2. 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.

3. Access Config and scroll to Edge Deployment and enable Enable pipelines deployed on the edge to send data back to the OpsCenter.

4. 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 Observabilty 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.

5. Save the updated configuration, then deploy it. Once complete, the edge observability service is available.

6. 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/ee/wallaroo --version 2023.4.0-4092 --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.

1. 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
   

2. 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.

Publish a Pipeline to the Edge Registry Service

See also the reference documentation: wallaroo.pipeline.publish.

Publish a Pipeline

Pipelines are published as images to the edge registry set in the Enable Wallaroo Edge Registry with the wallaroo.pipeline.publish method.

Publish a Pipeline Parameters

The publish method takes the following parameters. The containerized pipeline will be pushed to the Edge registry service with the model, pipeline configurations, and other artifacts needed to deploy the pipeline.

Publish a Pipeline Returns

Publish a Pipeline Example

The following example shows how to publish a pipeline to the edge registry service associated with the Wallaroo instance.

# set the configuration
deployment_config = wallaroo.DeploymentConfigBuilder().replica_count(1).cpus(0.5).memory("900Mi").build()

# build the pipeline
pipeline = wl.build_pipeline("publish-example")
# add a model as a model step
pipeline.add_model_step(m2)
publish = pipeline.publish(deployment_config)
display(publish)

List Publishes

All publishes created from a pipeline are displayed with the wallaroo.pipeline.publishes method.

List Publishes Parameters

N/A

List Publishes Returns

A List of the following fields:

List Publishes Example

The following shows a list of publishes from a pipeline.

pipeline.publishes()

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.

Add Edge

Wallaroo Servers edge deployments are added to a Wallaroo pipeline’s publish with the wallaroo.pipeline_publish.add_edge(name: string, tags: List[string]) method. The name is the unique primary key for each edge added to the pipeline publish and must be unique.

Add Edge Parameters

wallaroo.pipeline_publish.add_edge(name: string, tags: List[string]) has the following parameters.

Add Edge Returns

This returns a Publish Edge with the following fields:

Add Edge Example

The following example demonstrates creating a publish from a pipeline, then adding a new edge to the publish.

# create publish
xgb_pub=xgboost_pipeline_version.publish(deploy_config)
display(xgb_pub)

Waiting for pipeline publish... It may take up to 600 sec.
Pipeline is Publishing...Published.

xgb_edge = xgb_pub.add_edge("xgb-ccfraud-edge-publish")
print(xgb_edge)

Remove Edge

Edges are removed with the wallaroo.pipeline_publish.remove_edge(name: string)

Remove Edge Parameters

wallaroo.pipeline_publish.remove_edge(name: string) has the following parameters.

Remove Edge Returns

Null

Remove Edge Example

This example will add two edges to a pipeline publish, list the edges for the pipeline, then remove one of the edges.

edge_01_name = f'edge-ccfraud-observability{random_suffix}'
edge01 = pub.add_edge(edge_01_name)

edge_02_name = f'edge-ccfraud-observability-02{random_suffix}'
edge02 = pub.add_edge(edge_02_name)

pipeline.list_edges()

sample = pub.remove_edge(edge_02_name)
display(sample)

List Edges

The method wallaroo.pipeline.list_edges() displays any edges added to a pipeline’s publishes.

List Edges Parameters

None

List Edges Returns

The following fields are returned from a List of edges.

List Edges Example

edge_01_name = f'edge-ccfraud-observability{random_suffix}'
edge01 = pub.add_edge(edge_01_name)

edge_02_name = f'edge-ccfraud-observability-02{random_suffix}'
edge02 = pub.add_edge(edge_02_name)

pipeline.list_edges()

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:

• Set up authentication for Docker
• Authenticate with an Azure container registry
• Authenticating Amazon ECR Repositories for Docker CLI with Credential Helper

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.

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.

1. 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
   

2. 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.

   docker run -p 8080:8080 \
   -v ./data:/persist \
   -e DEBUG=true \
   -e OCI_REGISTRY=$REGISTRYURL \
   -e EDGE_BUNDLE=ZXhwb3J0IEJVTkRMRV9WRVJTSU9OPTEKZXhwb3J0IEVER0VfTkFNRT1lZGdlLWNjZnJhdWQtb2JzZXJ2YWJpbGl0eXlhaWcKZXhwb3J0IEpPSU5fVE9LRU49MjZmYzFjYjgtMjUxMi00YmU3LTk0ZGUtNjQ2NGI1MGQ2MzhiCmV4cG9ydCBPUFNDRU5URVJfSE9TVD1kb2MtdGVzdC5lZGdlLndhbGxhcm9vY29tbXVuaXR5Lm5pbmphCmV4cG9ydCBQSVBFTElORV9VUkw9Z2hjci5pby93YWxsYXJvb2xhYnMvZG9jLXNhbXBsZXMvcGlwZWxpbmVzL2VkZ2Utb2JzZXJ2YWJpbGl0eS1waXBlbGluZTozYjQ5ZmJhOC05NGQ4LTRmY2EtYWVjYy1jNzUyNTdmZDE2YzYKZXhwb3J0IFdPUktTUEFDRV9JRD03 \

   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 \
   -e PIPELINE_URL=ghcr.io/wallaroolabs/doc-samples/pipelines/edge-observability-pipeline:3b49fba8-94d8-4fca-aecc-c75257fd16c6 \
   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:

1. 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
   

2. Set up the compose.yaml file.

   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 with the volumes: tag.

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

       OCI_USERNAME:  _json_key_base64
       OCI_PASSWORD: abc123
       CONFIG_CPUS: 4
   

3. 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.

1. 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
   

2. 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}
   

3. 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.

1. Create the namespace to deploy the pipeline to. For example, the namespace wallaroo-edge-pipeline would be:

   kubectl create -n wallaroo-edge-pipeline
   

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

   1. 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}
      

   2. Specify the expended directory from the downloaded tgz file.

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

   3. 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}
      

3. 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`
   

Edge Deployment Endpoints

The following endpoints are available for API calls to the edge deployed pipeline.

List Pipelines

The endpoint /pipelines returns:

• id (String): The name of the pipeline.
• status (String): The status as either Running, or Error if there are any issues.

List Pipelines Example

curl localhost:8080/pipelines
{"pipelines":[{"id":"edge-cv-retail","status":"Running"}]}

List Models

The endpoint /models returns a List of models with the following fields:

• name (String): The model name.
• sha (String): The sha hash value of the ML model.
• status (String): The status of either Running or Error if there are any issues.
• version (String): The model version. This matches the version designation used by Wallaroo to track model versions in UUID format.

List Models Example

curl localhost:8080/models
{"models":[{"name":"resnet-50","sha":"c6c8869645962e7711132a7e17aced2ac0f60dcdc2c7faa79b2de73847a87984","status":"Running","version":"693e19b5-0dc7-4afb-9922-e3f7feefe66d"}]}

Edge Inference Endpoint

The inference endpoint takes the following pattern:

• /pipelines/{pipeline-name}: The pipeline-name is the same as returned from the /pipelines endpoint as id.

Wallaroo inference endpoint URLs accept the following data inputs through the Content-Type header:

• Content-Type: application/vnd.apache.arrow.file: For Apache Arrow tables.
• Content-Type: application/json; format=pandas-records: For pandas DataFrame in record format.

Once deployed, we can perform an inference through the deployment URL.

The endpoint returns Content-Type: application/json; format=pandas-records by default with the following fields:

• check_failures (List[Integer]): Whether any validation checks were triggered. For more information, see Wallaroo SDK Essentials Guide: Pipeline Management: Anomaly Testing.
• elapsed (List[Integer]): A list of time in nanoseconds for:
  • [0] The time to serialize the input.
  • [1…n] How long each step took.
• model_name (String): The name of the model used.
• model_version (String): The version of the model in UUID format.
• original_data: The original input data. Returns null if the input may be too long for a proper return.
• outputs (List): The outputs of the inference result separated by data type, where each data type includes:
  • data: The returned values.
  • dim (List[Integer]): The dimension shape returned.
  • v (Integer): The vector shape of the data.
• pipeline_name (String): The name of the pipeline.
• shadow_data: Any shadow deployed data inferences in the same format as outputs.
• time (Integer): The time since UNIX epoch.

Edge Inference Endpoint Example

The following example demonstrates sending an Apache Arrow table to the Edge deployed pipeline, requesting the inference results back in a pandas DataFrame records format.

curl -X POST localhost:8080/pipelines/edge-cv-retail -H "Content-Type: application/vnd.apache.arrow.file" -H 'Accept: application/json; format=pandas-records'  --data-binary @./data/image_224x224.arrow

Returns:

[{"check_failures":[],"elapsed":[1067541,21209776],"model_name":"resnet-50","model_version":"2e05e1d0-fcb3-4213-bba8-4bac13f53e8d","original_data":null,"outputs":[{"Int64":{"data":[535],"dim":[1],"v":1}},{"Float":{"data":[0.00009498586587142199,0.00009141524787992239,0.0004606838047038764,0.00007667174941161647,0.00008047101437114179,...],"dim":[1,1001],"v":1}}],"pipeline_name":"edge-cv-demo","shadow_data":{},"time":1694205578428}]

Edge Bundle Token Time To Live

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: The OCI registry URL to the containerized pipeline.
• WORKSPACE_ID: The numerical ID of the workspace.

For example:

{'edgeBundle': 'ZXhwb3J0IEJVTkRMRV9WRVJTSU9OPTEKZXhwb3J0IEVER0VfTkFNRT14Z2ItY2NmcmF1ZC1lZGdlLXRlc3QKZXhwb3J0IEpPSU5fVE9LRU49MzE0OGFkYTUtMjg1YS00ZmNhLWIzYjgtYjUwYTQ4ZDc1MTFiCmV4cG9ydCBPUFNDRU5URVJfSE9TVD1kb2MtdGVzdC5lZGdlLndhbGxhcm9vY29tbXVuaXR5Lm5pbmphCmV4cG9ydCBQSVBFTElORV9VUkw9Z2hjci5pby93YWxsYXJvb2xhYnMvZG9jLXNhbXBsZXMvcGlwZWxpbmVzL2VkZ2UtcGlwZWxpbmU6ZjM4OGMxMDktOGQ1Ny00ZWQyLTk4MDYtYWExM2Y4NTQ1NzZiCmV4cG9ydCBXT1JLU1BBQ0VfSUQ9NQ=='}

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.
