While performance will be worse, we can safely ignore the --stream
option when used, and print a deprecation warning instead of failing
the build.
With this patch:
echo -e "FROM scratch\nLABEL foo=bar" | docker build --stream -
DEPRECATED: The experimental --stream flag has been removed and the build context
will be sent non-streaming. Enable BuildKit instead with DOCKER_BUILDKIT=1
to stream build context, see https://docs.docker.com/go/buildkit/
Sending build context to Docker daemon 2.048kB
