AWS Sagemaker Operator

Sagemaker is a fully managed service for building ML models. BentoML provides great support for deploying BentoService to AWS Sagemaker without the additional process and work from users. With BentoML serving framework and bentoctl users can enjoy the performance and scalability of Sagemaker with any popular ML frameworks.

Note: This operator is compatible with BentoML version 1.0.0 and above. For older versions, please switch to the branch pre-v1.0 and follow the instructions in the README.md.

Quickstart with bentoctl

This quickstart will walk you through deploying a bento as an AWS Sagemaker Endpoint. Make sure to go through the prerequisites section and follow the instructions to set everything up.

Prerequisites

BentoML version 1.0 or above. Please follow the Installation guide.
Terraform - Terraform is a tool for building, configuring, and managing infrastructure. Installation instruction: www.terraform.io/downloads
AWS CLI - installed and configured with an AWS account with permission to Sagemaker, Lambda and ECR. Please follow the Installation guide.
Docker - Install instruction: docs.docker.com/install
A built Bento project. For this guide, we will use the Iris classifier bento from the BentoML quickstart guide. You can also use your own Bentos that are available locally.

Steps

Install bentoctl via pip
```
$ pip install bentoctl
```
Install AWS Sagemaker operator

Bentoctl will install the official AWS Sagemaker operator and its dependencies.
```
$ bentoctl operator install aws-sagemaker
```

Initialize deployment with bentoctl

Follow the interactive guide to initialize the deployment project.

$ bentoctl init

Bentoctl Interactive Deployment Config Builder

Welcome! You are now in interactive mode.

This mode will help you setup the deployment_config.yaml file required for
deployment. Fill out the appropriate values for the fields.

(deployment config will be saved to: ./deployment_config.yaml)

api_version: v1
name: quickstart
operator: aws-sagemaker
template: terraform
spec:
    region: ap-south-1
    instance_type: ml.t2.medium
    initial_instance_count: 1
    timeout: 60
    enable_data_capture: False
    destination_s3_uri:
    initial_sampling_percentage: 1
filename for deployment_config [deployment_config.yaml]:
deployment config generated to: deployment_config.yaml
✨ generated template files.
  - ./main.tf
  - ./bentoctl.tfvars

This will also run the bentoctl generate command for you and will generate the main.tf terraform file, which specifies the resources to be created and the bentoctl.tfvars file which contains the values for the variables used in the main.tf file.

Build and push AWS sagemaker compatible docker image to the registry

Bentoctl will build and push the sagemaker compatible docker image to the AWS ECR repository.

bentoctl build -b iris_classifier:latest -f deployment_config.yaml

The iris-classifier service is now built and pushed into the container registry and the required terraform files have been created. Now we can use terraform to perform the deployment.

Apply Deployment with Terraform

Initialize terraform project. This installs the AWS provider and sets up the terraform folders.
```
$ terraform init
```

Apply terraform project to create Sagemaker deployment

$ terraform apply -var-file=bentoctl.tfvars -auto-approve

Outputs:

ecr_image_tag = "213386773652.dkr.ecr.ap-south-1.amazonaws.com/quickstart:sfx3dagmpogmockr"

Test deployed endpoint

The iris_classifier uses the /classify endpoint for receiving requests so the full URL for the classifier will be in the form {EndpointUrl}/classify.

URL=$(terraform output -json | jq -r .endpoint.value)classify
curl -i \
  --header "Content-Type: application/json" \
  --request POST \
  --data '[5.1, 3.5, 1.4, 0.2]' \
  $URL

content-type: application/json
content-length: 1

0%

Note: You can also invoke the Sagemaker endpoint directly. If there is only one service, SageMaker deployment will choose that one. If there is more than one, you can specify which service to use by passing the X-Amzn-SageMaker-Custom-Attributes header with the name of the service as value.

Delete deployment Use the bentoctl destroy command to remove the registry and the deployment
```
bentoctl destroy -f deployment_config.yaml
```

Configuration Options

A sample configuration file has been given has been provided here. Feel free to copy it over and change it for you specific deployment values

region: AWS region where Sagemaker endpoint is deploying to
instance_type: The ML compute instance type for Sagemaker endpoint. See https://docs.aws.amazon.com/cli/latest/reference/sagemaker/create-endpoint-config.html for available instance types
initial_instance_count: Number of instances to launch initially.
timeout: timeout for API request in seconds
enable_data_capture: Enable Sagemaker capture data from requests and responses and store the captured data to AWS S3
destination_s3_uri: S3 bucket path for store captured data
initial_sampling_percentage: Percentage of the data will be captured to S3 bucket.

Troubleshooting

By default sagemaker is configured with cloudwatch for metrics and logs. To see the cloudwatch logs for the deployment

Open the Amazon Cloudwatch console at https://console.aws.amazon.com/cloudwatch/.
In the navigation pane, choose Logs -> Log groups.
Head over to /aws/sagemaker/Endpoints/-endpoint
Choose the latest logs streams
