# - use environment variables to overwrite this value (e.g export VERSION=0.0.2)

# IMAGE_TAG_BASE defines the docker.io namespace and part of the image name for remote images.
# This variable is used to construct full image tags for bundle and catalog images.
#
# For example, running 'make bundle-build bundle-push catalog-build catalog-push' will build and push both
# kkb0318.github.io/irsa-manager-bundle:$VERSION and kkb0318.github.io/irsa-manager-catalog:$VERSION.
