# Dirge computer-use testing image.
#
# Xvfb + Firefox + xdotool + scrot + Python vision deps.
# Provides a virtual display so the computer_use plugin can be tested
# without touching the host desktop.
#
# Build:
#   buildah bud --storage-driver vfs --tag dirge-computer-use:latest -f images/computer-use/Dockerfile .
#
# Run:
#   podman run --rm -it dirge-computer-use:latest
#   # Inside: DISPLAY=:99 is already set, Xvfb is running on :99
#   # Run dirge and test computer:navigate etc.
