The remote worker guide of bazel (here) explains how to start the remote-worker locally and then run bazel against it.
I tried it and indeed that worked (with bugs that reported in GH)
Another attempt was to create run the remote worker on a virtual separate machine, by running it inside docker container and running bazel against it. But it failed in a different way - and I think this time I'm using it wrong.
Here's my docker file:
FROM openjdk:8
# install release bazel from apt
RUN echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | tee /etc/apt/sources.list.d/bazel.list
RUN curl https://bazel.build/bazel-release.pub.gpg | apt-key add -
RUN apt-get update && apt-get install -y zip bazel
# compile dev bazel from sources
RUN mkdir -p /usr/src/bazel
# "bazel" has the latest development code of bazel from github
COPY bazel /usr/src/bazel
WORKDIR /usr/src/bazel
RUN bazel build src/bazel
# compile remote_worker using latest development bazel
RUN bazel-bin/src/bazel build //src/tools/remote_worker
# prepare cache folder
RUN mkdir -p /tmp/test
# Run remote-worker
CMD ["bazel-bin/src/tools/remote_worker/remote_worker","--work_path=/tmp/test","--listen_port=3030"]
After building it I simply ran the docker binding the port to the localhost:
$ docker build -t bazel-worker .
$ docker run -p 3030:3030 bazel-worker
Then ran bazel java test to run using the remote worker: (Can check out my test repo here)
$ bazel --host_jvm_args=-Dbazel.DigestFunction=SHA1 test \
--spawn_strategy=remote \
--remote_executor=localhost:3030 \
--remote_cache=localhost:3030 \
--strategy=Javac=remote \
--remote_local_fallback=false \
--remote_timeout=600 \
//src/main/java/com/example/...

Am I doing anything wrong? Do I need to run it differently when running the remote worker on an actual (or virtual) remote machine (vs. just running it locally)?
Important to mention: my machine is mac osx sierra. , I believe that docker openjdk:8 is ubuntu based, I'm running locally bazel development version (sha 956810b6ee24289e457a4b8d0a84ff56eb32c264).
