# Build package with chosen $(BUILDER)
|
|
# Supported BUILDERs: docker
|
|
# Usage: $(call build,core/$(NAME),$(VERSION),$(TARGET),$(EXTRA_ARGS))
|
|
# Notes:
|
|
# - Packages are expected to use the following layer names in order:
|
|
# - "fetch": [optional] obtain any artifacts from the internet.
|
|
# - "build": [optional] do any required build work
|
|
# - "package": [required] scratch layer exporting artifacts for distribution
|
|
# - "test": [optional] define any tests
|
|
# - Packages may prefix layer names with "text-" if more than one is desired
|
|
# - VERSION will be set as a build-arg if defined, otherwise it is "latest"
|
|
# - TARGET defaults to "package"
|
|
# - EXTRA_ARGS will be blindly injected
|
|
# - packages may also define a "test" layer
|
|
# - the ulimit line is to workaround a bug in patch when the nofile limit is too large:
|
|
# https://savannah.gnu.org/bugs/index.php?62958
|
|
# TODO:
|
|
# - try to disable networking on fetch layers with something like:
|
|
# $(if $(filter fetch,$(lastword $(subst -, ,$(TARGET)))),,--network=none)
|
|
# - actually output OCI files for each build (vs plain tar)
|
|
# - output manifest.txt of all tar/digest hashes for an easy git diff
|
|
# - support buildah and podman
|
