Hello,
I want to run Hadoline on an Alpine distrib (for Raspberri Pi 3) and, when I execute the command from the readme, I have this error message :

$ docker run --rm -i hadolint/hadolint < Dockerfile
exec user process caused "exec format error"

Expected behavior

The command must validate a Dockerfile.

Actual behavior

An error appears when I run this command on Alpine 3.9.2 (aarch64).

Steps to reproduce the behavior

Just run the hadolint container on Alpine 3.9.2 (aarch64).

Output of hadolint --version or
docker run --rm hadolint/hadolint hadolint --version:
Same error :

standard_init_linux.go:207: exec user process caused "exec format error"

Additional environment details (OS, stack version, etc.)

• Alpine 3.9.2 (aarch64)
• Docker version 18.09.1-ce, build 4c52b901c6cb019f7552cd93055f9688c6538be4
