A docker file to build the lotus filecoin client. Uses a multi-stage build to produce an image without uneeded build dependencies.
The lotus branch can be specified with the build arg BRANCH.
To build the ntwk-calibration branch run docker build . --build-arg BRANCH=ntwk-calibraiton. Branch defaults to master.
