# Build the netbird-dashboard Docker image for linux/amd64 and export it as a
# portable tarball that can be loaded and run on a remote server.
#
# The dashboard image is nginx serving a Next.js *static export*: the Dockerfile
# only COPYs the pre-built out/ directory, so we build out/ on the host first
# (the static files are arch-independent) and then assemble the amd64 image.
#
# Usage:
# ./build.sh # build + export netbird-dashboard.tar.gz
# IMAGE_TAG=v1 ./build.sh # override the image tag
# SKIP_BUILD=1 ./build.sh # reuse an existing out/ (skip npm build)
#
set -euo pipefail
# Always run relative to this script's directory (the project root).
