Actions runner image built with custom runner code not working as expected

[rpall08]

Trying to create actions runner image with custom runner code, below are changes in actions-runner.dockerfile.
copies custom built runner tag.gz file in actions-runner-controller/runner directory.

COPY ./runner.tar.gz /runnertmp/runner.tar.gz
ENV RUNNER_ASSETS_DIR=/runnertmp
RUN mkdir -p "$RUNNER_ASSETS_DIR"
&& cd "$RUNNER_ASSETS_DIR"
&& tar xzf ./runner.tar.gz
&& rm runner.tar.gz
&& ./bin/installdependencies.sh
&& mv ./externals ./externalstmp
&& apt-get install -y libyaml-dev
&& rm -rf /var/lib/apt/lists/*

Image built fine and then tried to start the container with these environment properties
RUNNER_TOKEN=******
RUNNER_ORG=******
RUNNER_NAME=**********

logs from runner container:

DEBUG --- Working with public GitHub
ERROR --- /runner should be an emptyDir mount. Please fix the pod spec.

Can anyone review, whats wrong in dockefile?
