# syntax=docker/dockerfile:1
# Hermes Agent -- custom fork build
# Builds on top of official image + overlays our forked source from Gitea.
# Requires Docker BuildKit. Pass SSH agent for git clone:
#   docker compose build hermes
# Or manually:
#   DOCKER_BUILDKIT=1 docker build --ssh default -t hermes-agent:custom .

# ---------- Base: official Hermes image (system deps, npm, uv, Playwright) ----------
FROM nousresearch/hermes-agent:latest

# ---------- Overlay our forked source ----------
# Uses SSH agent forwarding from the build host (no key baked into image).
# --exclude node_modules/.venv keeps the base image's pre-built layers intact.
# Only the Python source, web UI source, and config change.
