Honcho — self-hosted Docker package
This folder contains a ready-to-run Docker Compose setup for Honcho,
the memory server used by the personal-agent's Honcho plugin
(src/plugin/honcho/).
What runs
| Service | Image | Port | Role |
|---|---|---|---|
api |
ghcr.io/plastic-labs/honcho:latest |
8000 | REST API (the endpoint personal-agent talks to) |
deriver |
same image | — | Background worker: extracts conclusions, summaries, peer representations |
db |
pgvector/pgvector:pg17 |
5432 (internal) | PostgreSQL + pgvector (vector search) |
redis |
redis:7-alpine |
6379 (internal) | Cache for session context |
Data is stored in named Docker volumes (honcho_db, honcho_redis) and survives container restarts.
Prerequisites
- Docker ≥ 24 with Compose plugin (
docker compose version) - An LLM API key (OpenAI by default; OpenRouter and Ollama also supported — see LLM providers)
Quick start
# 1. Copy the env template
cp .env.example .env
# 2. Set your LLM key (minimum required)
# Open .env and fill in LLM_OPENAI_API_KEY=sk-...
# 3. Start all services (detached)
docker compose up -d
# 4. Verify the API is up
curl http://localhost:8000/health
# → {"status":"ok"}
# 5. Open interactive API docs
open http://localhost:8000/docs
The first startup takes ~30 s while Docker pulls the images and the database runs migrations.
Connect personal-agent
Enable the Honcho plugin in personal-agent by asking the main agent or using the REST API:
PUT /api/plugins/honcho
Content-Type: application/json
{
"enabled": true,
"config": {
"base_url": "http://localhost:8000",
"api_key": "",
"workspace_id": "personal-agent"
}
}
api_key— leave empty whenHONCHO_AUTH_TOKENis not set in.env.workspace_id— any string; used to namespace workspaces inside Honcho.
LLM providers
Honcho needs an LLM to run the deriver (background memory extraction). The API itself works without it, but no long-term conclusions will be built.
OpenAI (default)
LLM_OPENAI_API_KEY=sk-...
Defaults to gpt-4o-mini for text generation and text-embedding-3-small for embeddings.
OpenRouter
LLM_OPENAI_API_KEY=sk-or-...
DERIVER_MODEL_CONFIG__TRANSPORT=openai
DERIVER_MODEL_CONFIG__MODEL=openai/gpt-4o-mini
DERIVER_MODEL_CONFIG__OVERRIDES__BASE_URL=https://openrouter.ai/api/v1
Gives access to many models (Anthropic, Mistral, Gemini, …) on a single key.
Ollama (fully local — no data leaves the machine)
Requires Ollama running on the host with a function-calling model and an embedding model:
ollama pull llama3.3:70b
ollama pull nomic-embed-text
LLM_OPENAI_API_KEY=ollama
DERIVER_MODEL_CONFIG__TRANSPORT=openai
DERIVER_MODEL_CONFIG__MODEL=llama3.3:70b
DERIVER_MODEL_CONFIG__OVERRIDES__BASE_URL=http://host.docker.internal:11434/v1
LLM_EMBEDDING_API_KEY=ollama
LLM_EMBEDDING_BASE_URL=http://host.docker.internal:11434/v1
LLM_EMBEDDING_MODEL=nomic-embed-text
host.docker.internal resolves to the host machine from inside the container (works on
macOS and Windows; on Linux add --add-host=host.docker.internal:host-gateway to the
compose service if needed).
Useful commands
# Start / stop
docker compose up -d
docker compose down
# Follow logs
docker compose logs -f api
docker compose logs -f deriver
# Restart only the API after a config change
docker compose restart api
# Stop and wipe all data (destructive!)
docker compose down -v
# Upgrade to a newer Honcho image
docker compose pull
docker compose up -d
Build from source (alternative)
If the published image is unavailable or you want to run unreleased code:
# Clone the official Honcho repository next to this folder
git clone https://github.com/plastic-labs/honcho honcho-src
# In docker-compose.yml, replace the api/deriver `image:` lines with:
# build:
# context: ./honcho-src
docker compose up -d --build
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
api container exits immediately |
DB not ready | Check docker compose logs db; wait for "database system is ready" |
deriver keeps restarting |
Invalid LLM key or unreachable endpoint | Check docker compose logs deriver; verify .env |
curl http://localhost:8000/health returns connection refused |
Wrong port or container not started | Run docker compose ps; check HONCHO_PORT in .env |
personal-agent logs honcho: session_context failed |
API unreachable | Verify base_url in plugin config; check firewall / VPN |
| Conclusions not appearing after several chats | Deriver not running | Run docker compose logs deriver; check LLM key |
