deploy.yml

# Deploys deflua.com to Fly.io on every merge to main.
#
# The site builds from the repo root (Dockerfile + fly.toml here) because
# website/mix.exs has a `{:lua, path: ".."}` dependency, so changes to either
# the website or the lua library can affect what's deployed. Hence: deploy on
# any push to main.
#
# Requires a FLY_API_TOKEN secret. Create one with:
#   fly tokens create deploy -x 999999h
# then add it under Settings → Secrets and variables → Actions.

# Never run two deploys at once; if a newer commit lands mid-deploy, let the
# in-flight one finish (don't cancel) so we don't leave a half-rolled release.
