Multiarch docker obfs4 bridge
Having more images enables the bridge operators to directly pull an image instead of modifying the Dockerfile and consequently building that image. For example, the supported architectures can be x86_64, aarch64 and arm.
In order to do so we can have multiple
Dockerfile.arch where is used https://github.com/multiarch/qemu-user-static in order to build such image.
For example in the Dockerfile.arm file the content should be something like:
# Base docker image FROM multiarch/qemu-user-static:x86_64-arm as qemu FROM arm32v7/debian:buster-slim COPY --from=qemu /usr/bin/qemu-arm-static /usr/bin # Install remaining dependencies. RUN apt-get update && apt-get install -y \ tor \ tor-geoipdb \ obfs4proxy \ libcap2-bin \ --no-install-recommends # Allow obfs4proxy to bind to ports < 1024. RUN setcap cap_net_bind_service=+ep /usr/bin/obfs4proxy RUN setcap cap_net_bind_service=+ep /usr/bin/tor # Our torrc is generated at run-time by the script start-tor.sh. RUN rm /etc/tor/torrc RUN chown debian-tor:debian-tor /etc/tor RUN chown debian-tor:debian-tor /var/log/tor COPY start-tor.sh /usr/local/bin RUN chmod 0755 /usr/local/bin/start-tor.sh COPY get-bridge-line /usr/local/bin RUN chmod 0755 /usr/local/bin/get-bridge-line USER debian-tor CMD [ "/usr/local/bin/start-tor.sh" ]
