# Self-hosted Puter — full stack.
#
# Brings up Puter + every external service it needs:
#   - nginx    : reverse proxy (mirrors prod ALB; handles TLS + Host fan-out)
#   - valkey   : redis-compatible cache / rate-limiter backend
#   - mariadb  : SQL database (Puter applies its schema on first boot)
#   - dynamo   : DynamoDB-local (KV store; Puter creates the table itself)
#   - s3       : RustFS — S3-compatible object storage
#   - s3-init  : one-shot init container that creates the bucket
#   - puter    : the application
#
# Quick start:
#   1. Copy .env.example to .env (or set the variables in your shell).
#   2. Drop a config.json into ./puter/config/ — see selfhosted/full-stack.md
#      for the example that pairs with this compose.
#   3. docker compose up -d
#
# Easiest path:
#   curl -fsSL https://raw.githubusercontent.com/HeyPuter/puter/main/install.sh | sh
# grabs this file, generates secrets, writes .env + config.json, and runs
# the compose up for you.
#
# Production:
#   - Always replace the default passwords / S3 keys / Puter secrets.
#   - Front Puter with TLS-terminating reverse proxy (Caddy / nginx).
#   - Move state-bearing volumes to a backed-up location.
