Docker Installation

Docker is the recommended way to run Memoh. The stack includes PostgreSQL, the main server (with embedded Containerd and in-process AI agent), and the web UI — all orchestrated via Docker Compose. You do not need to install containerd, nerdctl, or buildkit on your host; everything runs inside containers.

Service Architecture

The Docker Compose stack consists of multiple services. Some are always started, others are optional and enabled via --profile:

Service	Profile	Description
server	(core)	Main Memoh server with embedded Containerd and in-process AI agent
web	(core)	Web UI (Vue 3)
postgres	(core)	PostgreSQL database
qdrant	qdrant	Qdrant vector database for memory search (sparse and dense modes)
browser	browser	Playwright-based browser gateway for bot web automation
sparse	sparse	Neural sparse encoding service for memory retrieval (see below)

Sparse Service

The sparse container provides neural sparse vector encoding for memory retrieval. It runs a lightweight Python (Flask) service on port 8085 that uses the opensearch-neural-sparse-encoding-multilingual-v1 model from OpenSearch.

What it does:

• Converts document text into sparse vectors (a compact list of token indices + importance weights) using a masked language model
• Encodes queries using IDF-weighted term lookup for fast, efficient retrieval
• Works with Qdrant to enable semantic memory search without requiring an external embedding API

Why use it:

• No embedding API costs — The model runs locally inside the container, so you don't need an OpenAI/Cohere/etc. embedding API key
• Multilingual — The underlying model supports multiple languages out of the box
• Good retrieval quality — Neural sparse encoding provides significantly better results than keyword-only search (BM25), while being lighter than dense embedding models

When to enable it:

Enable the sparse profile (--profile sparse) if you plan to use the built-in memory provider in sparse mode. The model is pre-downloaded during the Docker image build, so the container starts quickly without needing to fetch weights at runtime.

docker compose --profile qdrant --profile sparse --profile browser up -d

For more details on memory modes, see Built-in Memory Provider.

Prerequisites

• Docker
• Docker Compose v2
• Git

One-Click Install (Recommended)

Run the official install script (requires Docker and Docker Compose):

curl -fsSL https://memoh.sh | sudo sh

The script will:

1. Check for Docker and Docker Compose
2. Prompt for configuration (workspace, data directory, admin credentials, JWT secret, Postgres password, sparse service toggle, browser core selection)
3. Fetch the latest release tag from GitHub and clone the repository
4. Generate config.toml from the Docker template with your settings
5. Pin Docker image versions to the release
6. Build the browser image with selected cores and start all services

Silent install (use all defaults, no prompts):

curl -fsSL https://memoh.sh | sudo sh -s -- -y

Defaults when running silently:

• Workspace: ~/memoh
• Data directory: ~/memoh/data
• Admin: admin / admin123
• JWT secret: auto-generated
• Postgres password: memoh123

Install a specific version:

curl -fsSL https://memoh.sh | sudo sh -s -- --version v0.6.0

Or using the environment variable:

curl -fsSL https://memoh.sh | sudo MEMOH_VERSION=v0.6.0 sh

Use China mainland mirror (for slow image pulls):

curl -fsSL https://memoh.sh | sudo USE_CN_MIRROR=true sh

Environment variables can be combined, e.g. curl -fsSL https://memoh.sh | sudo MEMOH_VERSION=v0.6.0 USE_CN_MIRROR=true sh

Manual Install

git clone https://github.com/memohai/Memoh.git
cd Memoh
cp conf/app.docker.toml config.toml

Edit config.toml — at minimum change:

• admin.password — Admin password
• auth.jwt_secret — Generate with openssl rand -base64 32
• postgres.password — Database password (also set POSTGRES_PASSWORD env var to match)

Then start (recommended — with Qdrant, Browser, and Sparse):

sudo POSTGRES_PASSWORD=your-db-password docker compose --profile qdrant --profile browser --profile sparse up -d

Or start core services only (no vector DB or browser automation):

sudo POSTGRES_PASSWORD=your-db-password docker compose up -d

On macOS or if your user is in the docker group, sudo is not required.

Important: docker-compose.yml mounts ./config.toml by default. You must create this file before starting — running without it will fail.

China Mainland Mirror

For users in mainland China who cannot access Docker Hub directly, uncomment the registry line in config.toml:

[workspace]
registry = "memoh.cn"

And add the China mirror compose overlay:

sudo docker compose -f docker-compose.yml -f docker/docker-compose.cn.yml \
  --profile qdrant --profile browser up -d

The install script handles this automatically when you set USE_CN_MIRROR=true.

Access Points

After startup:

Service	URL
Web UI	http://localhost:8082
API	http://localhost:8080
Browser Gateway	http://localhost:8083

Default login: admin / admin123 (change this in config.toml).

First startup may take 1–2 minutes while images are pulled and services initialize.

Configuration Reference

The config.toml file controls all server behavior. Here is a summary of the available sections:

Section	Description
[log]	Logging level and format (info, debug; text, json)
[server]	HTTP listen address (default :8080)
[admin]	Admin account credentials (username, password, email)
[auth]	JWT secret and token expiration
timezone	Server timezone (default UTC)
[containerd]	Containerd socket path and namespace
[workspace]	Container image, snapshotter, data paths, CNI config, optional registry mirror
[postgres]	PostgreSQL connection (host, port, user, password, database, sslmode)
[qdrant]	Qdrant vector database connection (base_url, api_key, timeout)
[sparse]	Sparse encoding service URL
[registry]	Provider definitions directory
[browser_gateway]	Browser Gateway host, port, and server address
[web]	Web frontend host and port

Common Commands

Prefix with sudo on Linux if your user is not in the docker group.

docker compose up -d           # Start
docker compose down            # Stop
docker compose logs -f         # View logs
docker compose ps              # Status
docker compose pull && docker compose up -d  # Update to latest images
