# This script merges Coder Docker images of different architectures together
|
|
# into the specified target image+tag, or the arch-less image tag returned by
|
|
# ./image_tag.sh.
|
|
#
|
|
# Usage: ./build_docker_multiarch.sh [--version 1.2.3] [--target image:tag] [--push] image1:tag1 image2:tag2
|
|
#
|
|
# The supplied images must already be pushed to the registry or this will fail.
|
|
# Also, the source images cannot be in a different registry than the target
|
|
# image.
|
|
#
|
|
# If no version is specified, defaults to the version from ./version.sh.
|
|
#
|
|
# If no target tag is supplied, the arch-less image tag returned by
|
|
# ./image_tag.sh will be used.
|
|
#
|
|
# If the --push parameter is supplied, all supplied tags will be pushed.
|
|
#
|
|
# Returns the merged image tag.
