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. This applies to the inference engine only.

• The following options apply to the inference pipeline and the models assigned as pipeline steps.

  • gpus: Whether to allocate available gpus to the deployment. If no gpus are to be allocated, this options is not available. For more details on how to specify gpu resources based on the edge hardware configuration, see Docker Engine: Containers: Access an NVIDIA GPU For example, to allocate gpus to the inference pipeline:
    • --gpus all
  • cpus: The fractional number of cpus to apply. For example:
    • --cpus=1.25
    • --cpus=2.0
  • memory: The amount of ram to allocate in unit values of:
    • k: kilobyte
    • m: megabyte
    • g: gigabyte

  For example:

  • --memory=1536m
  • --memory=512k

• 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.

The following example shows deploying models in an edge environment with the following resources allocated:

• Wallaroo inference engine:
  • cpus: 1
• Inference Pipeline:
  • cpus: 1.25
  • memory: 1536m
  • gpus: true

docker run \
    -p $EDGE_PORT:8080 \
    -e OCI_USERNAME=$OCI_USERNAME \
    -e OCI_PASSWORD=$OCI_PASSWORD \
    -e PIPELINE_URL=sample-pipeline-url \
    -e CONFIG_CPUS=1.0 --gpus all --cpus=1.25 --memory=1536m \
    sample-engine-url

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=$REGISTRYURL \
   -e EDGE_BUNDLE=ZXhwb3J0IEJVTkRMRV9WRVJTSU9OPTEKZXhwb3J0IEVER0VfTkFNRT1lZGdlLWNjZnJhdWQtb2JzZXJ2YWJpbGl0eXlhaWcKZXhwb3J0IEpPSU5fVE9LRU49MjZmYzFjYjgtMjUxMi00YmU3LTk0ZGUtNjQ2NGI1MGQ2MzhiCmV4cG9ydCBPUFNDRU5URVJfSE9TVD1kb2MtdGVzdC5lZGdlLndhbGxhcm9vY29tbXVuaXR5Lm5pbmphCmV4cG9ydCBQSVBFTElORV9VUkw9Z2hjci5pby93YWxsYXJvb2xhYnMvZG9jLXNhbXBsZXMvcGlwZWxpbmVzL2VkZ2Utb2JzZXJ2YWJpbGl0eS1waXBlbGluZTozYjQ5ZmJhOC05NGQ4LTRmY2EtYWVjYy1jNzUyNTdmZDE2YzYKZXhwb3J0IFdPUktTUEFDRV9JRD03 \
   -e CONFIG_CPUS=1 \
   -e OCI_USERNAME=$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/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
   

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
       volumes:
           - ./data:/persist
   environment:
       PIPELINE_URL: sample-registry.com/pipelines/edge-cv-retail:bf70eaf7-8c11-4b46-b751-916a43b1a555

       OCI_REGISTRY: sample-registry.com
       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.

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} --timeout 10m --wait --wait-for-jobs
      

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

      helm install --namespace {namespace} --values {local values file} {helm install name} {helm directory path} --timeout 10m --wait --wait-for-jobs
      

   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} --timeout 10m --wait --wait-for-jobs
      

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`
