# combination.

# Usage: ./image_tag.sh [--arch amd64] [--version 1.2.3]

# The --arch parameter accepts a Golang arch specification. If not specified,
|
|
# the image tag for the multi-arch image will be returned instead.
|

#
|
|
# If no version is specified, defaults to the version from ./version.sh. If the
|
|
# supplied version is "latest", no `v` prefix will be added to the tag.
|
|
#
|
|
# The returned tag will be sanitized to remove invalid characters like the plus
|
|
# sign.
