emqx4.3/scripts/buildx.sh

#!/usr/bin/env bash

## This script helps to run docker buildx to build cross-arch/platform packages (linux only)
## It mounts (not copy) host directory to a cross-arch/platform builder container
## Make sure the source dir (specified by --src_dir option) is clean before running this script

## NOTE: it requires $USER in docker group
## i.e. will not work if docker command has to be executed with sudo

## example:
## ./scripts/buildx.sh --profile emqx --pkgtype tgz

set -euo pipefail
