# multi_arch_container produces a private internal container_image, multiple
|
|
# arch-specific tagged container_bundles (named NAME-ARCH) and aliases
|
|
# from NAME and NAME.tar to the appropriately NAME-ARCH container_bundle target
|
|
# for the currently-configured architecture.
|
|
# Args:
|
|
# name: name used for the alias; the internal container_image and
|
|
# container_bundles are based on this name
|
|
# architectures: list of architectures (in GOARCH naming parlance) to
|
|
# configure
|
|
# base: base image to use for the containers. The format string {ARCH} will
|
|
# be replaced with the configured GOARCH.
|
|
# docker_tags: list of docker tags to apply to the image. The format string
|
|
# {ARCH} will be replaced with the configured GOARCH; any stamping variables
|
|
# should be escaped, e.g. {{STABLE_MY_VAR}}.
|
|
# tags: will be applied to all rules
|
|
# visiblity: will be applied only to the container_bundles; the internal
|
|
# container_image is private
|
|
# All other args will be applied to the internal container_image.
