To those having problems building and running docker containers on ARM devices: Here are two workarounds for getting containers built at least.

First, the ugly one. Run the build in a loop until it is successful:

while [ 1 ]; do sudo docker build .; if [ $? -ne 1 ]; then break; fi; done

The other one is a fantastic trick. Use qemu to build the ARM images on your x86 system! See this post for the howto.

# Run like this:

# Inside the twister-core source directory, run:
sudo ./twister-on-docker build
sudo docker run --rm -v $(pwd):/target --entrypoint /usr/bin/env twister cp /twister-core/twisterd /target
# Now twisterd should be there!
file twisterd


# Alternatively, get the current twisterd from the automatic build:
sudo docker pull miguelfreitas/twister
sudo docker run --rm -v $(pwd):/target --entrypoint /usr/bin/env miguelfreitas/twister cp /twister-core/twisterd /target
