# Three-container Docker Compose: Hermes Agent + Dashboard + WebUI
#
# QUICK START:
#   docker compose -f docker-compose.three-container.yml up -d
#   Open http://localhost:8787 (chat) and http://localhost:9119 (dashboard)
#
# This extends the two-container setup with the Hermes Dashboard for
# monitoring agent activity, sessions, and resource usage.
#
# Services:
#   hermes-agent     — gateway API on port 8642 (CLI, Telegram, cron, tools)
#   hermes-dashboard — monitoring dashboard on port 9119
#   hermes-webui     — browser chat interface on port 8787
#
# All three share the same hermes-home volume so config, sessions,
# skills, and memory are consistent across all surfaces.
#
# WHEN NOT TO USE THIS:
#   - You hit "Permission denied" trying to share an existing ~/.hermes directory
#     → use docker-compose.yml (single-container) instead, OR
#     → keep this file but switch to NAMED VOLUMES (the default) instead of bind mounts
#   - You're on Podman 3.4 or older without keep-id namespace support
#     → see https://github.com/sunnysktsang/hermes-suite for an all-in-one image
#
# KNOWN LIMITATION (#681): tools triggered from the WebUI run in the WebUI
# container, not the agent container. See docker-compose.two-container.yml
# for context.
#
# NOTE ON VOLUMES:
#   This file uses named Docker volumes (hermes-home, hermes-agent-src) which
#   work out of the box. If you prefer bind mounts (e.g. to an existing
#   directory), see docker-compose.two-container.yml for a bind-mount example.
#   When using bind mounts, ALL THREE containers must mount the same host path
#   AND run as the same UID/GID (set via the UID/GID env vars below).
