Configuring OpenClaw’s Memory Layers on UBOS: A Step‑by‑Step Guide

Introduction

OpenClaw is a powerful, open‑source AI orchestration engine that relies on a layered memory architecture to balance speed, cost, and persistence. When you run OpenClaw on UBOS, you gain access to a unified platform that simplifies deployment, scaling, and monitoring. This guide walks developers through the step‑by‑step process of configuring short‑term, mid‑tier, and long‑term memory on UBOS, complete with code snippets, common pitfalls, and troubleshooting tips.

By the end of this article you will be able to:

• Provision a fast in‑memory cache for immediate context (short‑term memory).
• Set up a cost‑effective vector store for semantic retrieval (mid‑tier memory).
• Configure durable blob storage for archival knowledge (long‑term memory).
• Deploy a fully functional OpenClaw instance using the OpenClaw hosting guide.

Overview of OpenClaw Memory Architecture

Short‑term Memory

Short‑term memory (STM) lives in RAM and is designed for sub‑second latency. It stores the most recent user inputs, system prompts, and transient embeddings that the LLM needs for the current conversation.

Mid‑tier Memory

Mid‑tier memory (MTM) balances speed and cost by using a vector database such as Chroma DB integration. It retains semantic embeddings for a longer horizon (hours to days) and enables similarity search across past interactions.

Long‑term Memory

Long‑term memory (LTM) persists knowledge indefinitely. Typical back‑ends include object storage (e.g., S3‑compatible buckets) or relational databases. LTM is used for policy documents, knowledge bases, and audit logs.

Prerequisites

• A running UBOS platform (v2.5+ recommended).
• Access to the UBOS partner program for API keys if you plan to use premium services.
• Docker installed on your development machine (UBOS uses containerized services).
• Basic familiarity with environment variables and YAML configuration files.
• Optional: OpenAI ChatGPT integration for LLM calls.

Setting Up Short‑term Memory on UBOS

UBOS provides a built‑in Redis service that is perfect for STM. Follow these steps to enable it for OpenClaw.

Step 1: Enable Redis in the UBOS Service Catalog

services:
  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"
    restart: always

Step 2: Add STM Configuration to OpenClaw

memory:
  short_term:
    type: redis
    host: localhost
    port: 6379
    ttl_seconds: 300   # 5 minutes

Common Issues & Fixes

Configuring Mid‑tier Memory

Mid‑tier memory leverages a vector store. UBOS’s Chroma DB integration offers a fully managed, scalable solution.

Step 1: Deploy Chroma DB via UBOS

services:
  chroma:
    image: chromadb/chroma:latest
    environment:
      - CHROMA_DB_DIR=/data/chroma
    volumes:
      - ./chroma-data:/data/chroma
    ports:
      - "8000:8000"
    restart: always

Step 2: Connect OpenClaw to Chroma

memory:
  mid_tier:
    type: chroma
    endpoint: http://localhost:8000
    collection_name: openclaw_embeddings
    dimension: 1536

Troubleshooting Tips

curl -X POST http://localhost:8000/api/v1/collections \
  -H "Content-Type: application/json" \
  -d '{"name":"openclaw_embeddings","dimension":1536}'

Deploying Long‑term Memory

Long‑term memory is best served by an object store. UBOS can provision an S3‑compatible bucket using MinIO.

Step 1: Spin up MinIO

services:
  minio:
    image: minio/minio:latest
    command: server /data
    environment:
      - MINIO_ROOT_USER=admin
      - MINIO_ROOT_PASSWORD=SuperSecret123
    ports:
      - "9000:9000"
    volumes:
      - ./minio-data:/data
    restart: always

Step 2: Configure LTM in OpenClaw

memory:
  long_term:
    type: s3
    endpoint: http://localhost:9000
    access_key: admin
    secret_key: SuperSecret123
    bucket: openclaw-archive
    region: us-east-1
    storage_class: STANDARD

Debugging Long‑term Storage

mc mb myminio/openclaw-archive
mc policy set public myminio/openclaw-archive

Full Example Workflow

Below is a consolidated docker-compose.yml that brings together STM, MTM, and LTM services with OpenClaw.

version: "3.8"
services:
  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"
    restart: always

  chroma:
    image: chromadb/chroma:latest
    environment:
      - CHROMA_DB_DIR=/data/chroma
    volumes:
      - ./chroma-data:/data/chroma
    ports:
      - "8000:8000"
    restart: always

  minio:
    image: minio/minio:latest
    command: server /data
    environment:
      - MINIO_ROOT_USER=admin
      - MINIO_ROOT_PASSWORD=SuperSecret123
    ports:
      - "9000:9000"
    volumes:
      - ./minio-data:/data
    restart: always

  openclaw:
    image: openclaw/openclaw:latest
    depends_on:
      - redis
      - chroma
      - minio
    environment:
      - OPENCLAW_STM_TYPE=redis
      - OPENCLAW_STM_HOST=redis
      - OPENCLAW_STM_PORT=6379
      - OPENCLAW_STM_TTL=300
      - OPENCLAW_MTM_TYPE=chroma
      - OPENCLAW_MTM_ENDPOINT=http://chroma:8000
      - OPENCLAW_MTM_COLLECTION=openclaw_embeddings
      - OPENCLAW_MTM_DIM=1536
      - OPENCLAW_LTM_TYPE=s3
      - OPENCLAW_LTM_ENDPOINT=http://minio:9000
      - OPENCLAW_LTM_ACCESS_KEY=admin
      - OPENCLAW_LTM_SECRET_KEY=SuperSecret123
      - OPENCLAW_LTM_BUCKET=openclaw-archive
    ports:
      - "8080:8080"
    restart: always

Deploy with docker compose up -d. Once the stack is healthy, you can interact with OpenClaw via its REST API at http://localhost:8080/api/v1/. The short‑term cache will handle immediate context, the Chroma vector store will answer similarity queries, and MinIO will archive all conversation logs for compliance.

FAQ & Additional Resources

Do I need to pay for the Redis and MinIO services?

Both are open‑source and run free inside your UBOS environment. You only incur costs for the underlying compute resources, which you can control via the UBOS pricing plans.

Can I replace Chroma with Pinecone or Weaviate?

Yes. OpenClaw’s memory abstraction layer allows you to swap the vector store by updating the type and endpoint fields. For Pinecone, see the OpenAI ChatGPT integration page for API‑key handling.

How do I secure the memory services?

Use UBOS’s built‑in partner program to obtain TLS certificates and configure firewall rules. Additionally, set strong passwords for MinIO and enable Redis AUTH.

Where can I find more sample templates?

Explore the UBOS templates for quick start. For AI‑focused utilities, check out the AI SEO Analyzer or the AI Article Copywriter template.

Conclusion

Configuring OpenClaw’s memory layers on UBOS is straightforward once you understand the role of each tier. By leveraging Redis for short‑term cache, Chroma DB for semantic mid‑tier storage, and MinIO for durable long‑term archives, you create a balanced, cost‑effective AI stack that scales with your application’s needs.
