This service deploys LibreChat, an open-source AI chat platform that supports OpenAI, Anthropic, Google, Ollama, and many other providers in a single unified interface with conversation history, file uploads, code execution, and multi-user support.

Services

librechat: The LibreChat web application (Node.js).
mongodb: MongoDB database for conversation and user data.
meilisearch: Full-text search engine for message indexing.

Quick Start

Copy .env.example to .env:
```
cp .env.example .env
```

Update the secrets in .env (generate with openssl rand -hex 32):

JWT_SECRET, JWT_REFRESH_SECRET, MEILI_MASTER_KEY, CREDS_KEY, CREDS_IV

Start the services:
```
docker compose up -d
```
Open http://localhost:3080 and register the first user account.

`JWT_SECRET`	JWT signing secret (min 32 chars) — CHANGEME	placeholder
`JWT_REFRESH_SECRET`	JWT refresh signing secret — CHANGEME	placeholder
`MEILI_MASTER_KEY`	Meilisearch master key — CHANGEME	placeholder
`CREDS_KEY`	Encryption key for stored credentials (exactly 32 chars)	placeholder

Security Notes

Generate all secrets before any external exposure: openssl rand -hex 32
CREDS_KEY and CREDS_IV encrypt stored API keys — losing them makes stored credentials unrecoverable.
Set ALLOW_REGISTRATION=false after creating admin accounts to lock down signups.
