# Build and push the cfddns Docker image.
# The actual Dockerfile + Go source lives in a separate Gitea repo:
#   https://git.alexzaw.dev/alexz/cloudflare-ddns
# This script clones (or updates) that repo into /tmp/cfddns-build and runs
# `docker build` + `docker push`. Any positional args are forwarded to
# `docker build` (e.g. `./build.sh --no-cache`).
