SAM Deployment

SAM Deployment

Deploy Loki using the AWS Serverless Application Model (SAM) CLI.

Prerequisites

• SAM CLI installed

Quick Start

sam deploy \
  --template-file template.yaml \
  --stack-name my-openclaw \
  --region us-east-1 \
  --parameter-overrides \
    EnvironmentName=my-openclaw \
    InstanceType=t4g.xlarge \
    ModelMode=bedrock \
  --capabilities CAPABILITY_NAMED_IAM CAPABILITY_AUTO_EXPAND \
  --no-confirm-changeset

Or use guided mode for interactive parameter input:

sam deploy --guided --template-file template.yaml

What's Different from CloudFormation?

The SAM template uses Transform: AWS::Serverless-2016-10-31 and AWS::Serverless::Function for the Lambda custom resources. This means:

• SAM auto-generates IAM execution roles for Lambda functions (using Policies instead of separate AWS::IAM::Role resources)
• Requires CAPABILITY_AUTO_EXPAND in addition to CAPABILITY_NAMED_IAM
• Otherwise identical infrastructure and parameters

Outputs

Same as the CloudFormation template — InstanceId, PublicIp, SSMConnect, RoleArn, VpcId.

Notes

• No S3 bucket required — all Lambda code is inline (InlineCode)
• Stack creation takes ~8–10 minutes
• Use sam delete --stack-name my-openclaw to tear down
