# AWS CloudFormation Amazon Bedrock

## Overview

Creates production-ready AI infrastructure using AWS CloudFormation templates for Amazon Bedrock. Covers Bedrock agents, knowledge bases for RAG implementations, data source connectors, guardrails for content moderation, prompt management, workflow orchestration with flows, and inference profiles for optimized model access.

## When to Use

- Creating Bedrock agents with action groups
- Implementing RAG with knowledge bases
- Configuring S3 or web crawl data sources
- Setting up content moderation guardrails
- Managing prompt templates
- Orchestrating AI workflows with Bedrock Flows
- Configuring inference profiles for multi-model access
- Organizing templates with Parameters and cross-stack references

## Instructions

### 1. Define Parameters

```yaml
Parameters:
  FoundationModel:
    Type: String
    Default: anthropic.claude-3-sonnet-20240229-v1:0
    AllowedValues:
      - anthropic.claude-3-sonnet-20240229-v1:0
      - anthropic.claude-3-haiku-20240307-v1:0
      - amazon.titan-text-express-v1
    Description: Foundation model for agent
```

### 2. Create Agent Role

```yaml
Resources:
  AgentRole:
    Type: AWS::IAM::Role
    Properties:
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: Allow
            Principal:
              Service: bedrock.amazonaws.com
            Action: sts:AssumeRole
      Policies:
        - PolicyName: BedrockPermissions
          PolicyDocument:
            Version: "2012-10-17"
            Statement:
              - Effect: Allow
                Action:
                  - bedrock:InvokeModel
                Resource: !Sub "arn:aws:bedrock:${AWS::Region}:${AWS::AccountId}:foundation-model/${FoundationModel}"
```

### 3. Create Agent

```yaml
  BedrockAgent:
    Type: AWS::Bedrock::Agent
    Properties:
      AgentName: !Sub "${AWS::StackName}-agent"
      AgentResourceRoleArn: !GetAtt AgentRole.Arn
      FoundationModelArn: !Sub "arn:aws:bedrock:${AWS::Region}::foundation-model/${FoundationModel}"
      AutoPrepare: true
      Instruction: |
        You are a helpful assistant. Use the knowledge base to answer questions.
```

### 4. Create Knowledge Base

```yaml
  KnowledgeBaseRole:
    Type: AWS::IAM::Role
    Properties:
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: Allow
            Principal:
              Service: bedrock.amazonaws.com
            Action: sts:AssumeRole

  KnowledgeBase:
    Type: AWS::Bedrock::KnowledgeBase
    Properties:
      Name: !Sub "${AWS::StackName}-kb"
      RoleArn: !GetAtt KnowledgeBaseRole.Arn
      KnowledgeBaseConfiguration:
        Type: VECTOR
        VectorKnowledgeBaseConfiguration:
          EmbeddingModelArn: !Sub "arn:aws:bedrock:${AWS::Region}::embedding-model/amazon.titan-embed-text-v1"
```

### 5. Create Data Source

```yaml
  DataBucket:
    Type: AWS::S3::Bucket

  S3DataSource:
    Type: AWS::Bedrock::DataSource
    Properties:
      KnowledgeBaseId: !Ref KnowledgeBase
      Name: s3-data-source
      Type: S3
      DataSourceConfiguration:
        S3Configuration:
          BucketArn: !GetAtt DataBucket.Arn
          InclusionPrefixes:
            - documents/
```

### 6. Add Guardrail

```yaml
  Guardrail:
    Type: AWS::Bedrock::Guardrail
    Properties:
      Name: !Sub "${AWS::StackName}-guardrail"
      BlockedInputMessaging: "I cannot help with that request."
      ContentPolicyConfig:
        filtersConfig:
          - type: PROFANITY
          - type: MISCONDUCT
```

### 7. Create Action Group

```yaml
  ActionLambdaFunction:
    Type: AWS::Lambda::Function
    Properties:
      Runtime: python3.12
      Handler: index.handler
      Role: !GetAtt ActionLambdaRole.Arn
      Code:
        ZipFile: |
          def handler(event, context):
              return {"statusCode": 200, "body": "{\"result\": \"success\"}"}

  ActionGroup:
    Type: AWS::Bedrock::AgentActionGroup
    Properties:
      ActionGroupName: api-operations
      ActionGroupState: ENABLED
      AgentId: !GetAtt BedrockAgent.AgentId
      ActionGroupExecutor:
        Lambda: !Ref ActionLambdaFunction
      FunctionSchema:
        functionConfigurations:
          - function: |
              { "name": "get_inventory", "description": "Get current inventory status", "parameters": { "type": "object", "properties": { "sku": { "type": "string" } }, "required": [] } }
```

### 8. Validate Before Deploy

Always validate the template before deployment:

```bash
aws cloudformation validate-template --template-body file://bedrock-template.yaml
```

### 9. Verify After Deploy

```bash
# Check agent status
aws bedrock-agent get-agent --agent-id $(aws cloudformation describe-stacks --stack-name STACK_NAME --query 'Stacks[0].Outputs[?OutputKey==`AgentId`].OutputValue' --output text)

# Check knowledge base sync status
aws bedrock-agent list-knowledge-bases --agent-id AGENT_ID

# Test guardrail
aws bedrock-runtime apply_guardrail --guardrail-identifier GUARDRAIL_ID --source SOURCE
```
