Connecting to Docker

Ferrodock connects to the platform's default Docker endpoint:

Platform	Default
Windows	npipe:////./pipe/docker_engine
macOS, Linux	unix:///var/run/docker.sock

To use a different engine, set DOCKER_HOST before starting Ferrodock:

# Docker Desktop on macOS, if "Allow the default Docker socket" is off
DOCKER_HOST=unix://$HOME/.docker/run/docker.sock ferrodock

# Colima
DOCKER_HOST=unix://$HOME/.colima/default/docker.sock ferrodock

# Rancher Desktop (macOS)
DOCKER_HOST=unix://$HOME/.rd/docker.sock ferrodock

To launch the macOS app bundle with a custom host:

DOCKER_HOST=unix://$HOME/.colima/default/docker.sock \
  /Applications/Ferrodock.app/Contents/MacOS/ferrodock

When Docker isn't running

Ferrodock shows a "Docker isn't running" screen and keeps checking in the background. As soon as the engine is up, it connects on its own.
