This was breaking the release process. Namely it was running the `gen` targets due to the dependency tree, which was failing on macOS and Linux runners. This revert can be reverted once we fix that up.

# This script builds a Docker image of Coder containing the given binary, for
|
|
# the given architecture. Only linux binaries are supported at this time.
|
|
#
|
|
# Usage: ./build_docker.sh --arch amd64 [--version 1.2.3] [--push] path/to/coder
|
|
#
|
|
# The --arch parameter is required and accepts a Golang arch specification. It
|
|
# will be automatically mapped to a suitable architecture that Docker accepts
|
|
# before being passed to `docker buildx build`.
|
|
#
|
|
# The image will be built and tagged against the image tag returned by
|
|
# ./image_tag.sh.
|
|
#
|
|
# If no version is specified, defaults to the version from ./version.sh.
|
|
#
|
|
# If the --push parameter is supplied, the image will be pushed.
|
|
#
|
|
# Prints the image tag on success.
