[denzuko]

• Steps to reproduce

  1. load docker on raspberry pi
  2. launch service as stated in documentation
  3. execute docker service logs <service name used in deployment>

• Additional Details
  Logs:

standard_init_linux.go:211: exec user process caused "exec format error",
standard_init_linux.go:211: exec user process caused "exec format error",
standard_init_linux.go:211: exec user process caused "exec format error",

Doing discovery, it would show that there is no a multiarch binary/container uploaded to docker hub.

• Suggested changes

Add a multiarch binary and docker image as outlined in https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/
