# This script is used to build a Docker image for Icinga 2.
# Action defines the type of build to perform. It can be one of:
#
# - load: Build the image for the building platform and load it into the local Docker engine image storage.
# - push: Build the image for all specified platforms and push them to the Docker registry (icinga/icinga2:<TAG>).
# - cache: Build the image for all specified platforms using the default Buildx's exporter (cacheonly) and will just
# create a cache for each platform. There will be no images that you can use but any subsequent build will use the
# cache and speed up the build process.
#
# If no action is provided, it defaults to "load", and any specified platforms will be ignored.
ACTION="${1:-load}"
# Tag defines the tag to use for the built image. If not provided, it defaults to "test".
# The resulting image will be tagged as "icinga/icinga2:<TAG>".
TAG="${2:-test}"
# Platform defines the platforms to build the image for. It defaults to "linux/amd64,linux/arm64/v8".
PLATFORM="${3:-linux/amd64,linux/arm64/v8}"
# ROOT_DIR is the root directory of the Icinga 2 source code repository and where the Containerfile is located.
# It's also used to determine the build context for the Docker build, so that every file referenced in the
# Containerfile can be found relative to this directory by Docker.
ROOT_DIR="$(dirname "$(realpath "$0")")/../.."
