Building a Production AI Agent on Amazon Bedrock AgentCore From Code to Deployment

This blog shows how to build a production-ready LLMOps deployment pipeline for Amazon Bedrock AgentCore using CI/CD, automated testing, security, and observability. It solves the challenge of manual and inconsistent AI agent deployments by providing a scalable, repeatable, and enterprise-ready approach that accelerates releases while ensuring governance, reliability, and operational excellence.

🔗 Where We Left Off (From the Previous Blog)

In my  previous blog , " How I Built an IT Operations Agent That Actually Fixes Things (Not Just Reports Them) ", I built and deployed an IT Operations Agent on AgentCore Runtime with:
  • ✅ 12 tools (CloudWatch, EC2, SSM, SNS, CloudTrail, Knowledge Base)
  • ✅ CI/CD pipeline (CodeCommit → CodeBuild → ECR → AgentCore)
  • ✅ Production deployment (Runtime v8, all tests passing)
What was MISSING from that deployment:
  • ❌ No evaluation — how do we know the agent's answers are good?
  • ❌ No guardrails — what stops prompt injection or PII leaks?
  • ❌ No observability traces — can't see what the agent did step-by-step
  • ❌ No cost optimization — using Claude Sonnet ($3/1M tokens) without considering alternatives
  • ❌ No memory — agent forgets everything between sessions
This blog series adds all of that. We take the same agent pattern and build a complete LLMOps pipeline around it.

What We Built

A production-ready DevOps AI Agent that monitors, diagnoses, and remediates AWS infrastructure deployed on Amazon Bedrock AgentCore Runtime with full CI/CD automation.
Stack:
  • Agent Framework: Strands Agents + Amazon Nova Pro
  • Runtime: AgentCore (serverless container, ARM64)
  • Security: Bedrock Guardrails (content + PII + prompt injection defense)
  • Memory: Dual Architecture — AgentCore Memory (semantic) + DynamoDB (structured)
  • CI/CD: CodePipeline V2 → CodeBuild (ARM64) → ECR → AgentCore auto-deploy
  • Observability: OpenTelemetry + CloudWatch




Architecture






The Agent

6 tools, 1 model, 1 system prompt:
from strands import Agent
from strands.models import BedrockModel

MODEL_ID = "us.amazon.nova-pro-v1:0"  # AWS credits covered

agent = Agent(
    model=BedrockModel(model_id=MODEL_ID, region_name="us-east-1"),
    system_prompt="You are a production DevOps AI Agent...",
    tools=[get_alarms, get_metric_statistics, describe_instances, 
           manage_instance, run_command, send_notification]
)

Guardrail Configuration:
  • Content filter: PROMPT_ATTACK=HIGH, Violence/Hate/Sexual=HIGH
  • PII: SSN/Credit Card=BLOCK, Email/Phone=ANONYMIZE
  • Topics: Credential exposure=DENY, Destructive operations=DENY



Deployment: The Dockerfile


FROM public.ecr.aws/docker/library/python:3.13-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY agent/main.py agent/agent.py ./
COPY agent/tools/ ./tools/
EXPOSE 8080
CMD ["opentelemetry-instrument", "python", "main.py"]
Key: AgentCore requires ARM64. Use  opentelemetry-instrument  for auto-tracing.


CI/CD Pipeline (CodePipeline V2 + Auto-Deploy)

The full pipeline triggers automatically on every  git push  to main:
┌──────────────┐     ┌───────────────┐     ┌─────────────────┐     ┌──────────────┐

Dual Memory Architecture (AgentCore + DynamoDB)

The agent uses two complementary memory backends — each handling what it does best:
┌─────────────────────────────────────────────────────────────┐
│                      DualMemory                             │
├─────────────────────────────┬───────────────────────────────┤
│   AgentCore Memory          │      DynamoDB Memory          │
│   (Managed, AI-powered)     │   (Structured, explicit)      │
├─────────────────────────────┼───────────────────────────────┤
│ • Semantic extraction       │ • User preferences            │
│ • Session summaries         │ • Action history log          │
│ • Similarity retrieval      │ • Explicit remember/recall    │
│ • Auto-consolidation        │ • TTL-based expiry (90 days)  │
│ • Cross-session context     │ • Key-value structured data   │
└─────────────────────────────┴───────────────────────────────┘
Why two backends instead of one?
Use Case
Best Backend
Why
"Remember that I prefer JSON output"
DynamoDB
Explicit preference, exact recall
"What did we discuss about EC2 issues?"
AgentCore
Semantic search over conversations
"Summarize my last 3 sessions"
AgentCore
Built-in summarization strategy
"What actions did the agent take?"
DynamoDB
Structured history with timestamps
AgentCore Memory Configuration:
# Created via bedrock-agentcore-control API
memory_id = "llmops_agent_memory-iLAWGd3iCh"
strategies = [
    {"semanticMemoryStrategy": {"name": "conversation_context", ...}},
    {"summaryMemoryStrategy": {"name": "session_summaries", ...}}
]
Data Flow:
  1. Request arrives →  build_context()  queries BOTH backends
  1. AgentCore returns semantically relevant past conversations
  1. DynamoDB returns explicit user preferences and action history
  1. Both contexts are combined and injected into the prompt
  1. After response →  store_interaction()  saves to both backends
Code Integration:
from memory import DualMemory

memory = DualMemory()  # Initializes both backends

# Build context from both
context = memory.build_context(user_id, prompt)

# Store after processing
memory.store_interaction(user_id, session_id, prompt, response)





Challenges & Solutions

#
Error
Fix
1
 exit code 252  — wrong CLI
Use  bedrock-agentcore-control  (control plane)
2
 Architecture incompatible: arm64 
Switch CodeBuild to  ARM_CONTAINER 
3
 429 Too Many Requests  Docker Hub
Use  public.ecr.aws/docker/library/python:3.13-slim 
4
 AccessDeniedException: iam:PassRole 
Add PassRole to CodeBuild role
5
 Model marked as Legacy 
Use inference profile:  us.amazon.nova-pro-v1:0 
6
Marketplace 403 on Claude
Switch to Amazon Nova Pro (credits covered)

🔧 Errors Encountered (v14 → v24) — All 17 Fixed

Building from v14 to v24, we hit 17 distinct errors across CI/CD, container runtime, guardrails, frontend, and memory.
Category
Count
Key Errors
CI/CD Pipeline
4
YAML multi-line blocks, CodeCommit 403, wrong EventBridge trigger type, wrong pip package
Container Runtime
4
Missing guardrails.py in COPY, xray propagator not installed, raw HTTP vs BedrockAgentCoreApp, memory metadata format
Guardrails
2
ApplyGuardrail format validation, DRAFT version not blocking
Frontend (Streamlit)
4
Missing imports, duplicate element keys, stale memory, config overwrites
Memory Creation
2
Name regex validation, summary strategy namespace template
IAM
1
Missing  bedrock-agentcore:BatchCreateMemoryRecords  permission
Biggest lesson: AgentCore container runtimes use  BedrockAgentCoreApp  SDK — NOT raw HTTP servers on port 8080. This cost 3 failed deployments to discover.


Key Takeaways

  1. ARM64 from day one — AgentCore requires it, save yourself failed builds
  1.  bedrock-agentcore-control  for management,  bedrock-agentcore  for invocations
  1. Nova Pro — best price/performance for agents, covered by AWS credits
  1. Guardrails are non-negotiable — prompt injection defense must be ON in production
  1.  --cli-input-json file://  — never fight shell escaping for complex JSON

What's Next: The Agent Works — But Is It Any Good?

We have a deployed, working agent. But how do we know:
  • Are the answers correct?
  • Is it safe?
  • Does it pick the right tools?
  • Is it getting better or worse over time?

→ Part 2: Getting Managed Evaluation Working on Container Runtimes

In Part 2, I configure 9 evaluators (5 built-in + 4 custom with Nova Pro as judge) and discover that getting evaluation to work on container runtimes requires solving 7 challenges — including one undocumented fix ( session.id  baggage) that took an entire night to find.
