Setting up the game infrastructure

1. Clone this repo on the master machine.
2. Create the infrastructure files, which list the source and sink machines.
   • We currently create these files from the Ansible inventory of machines:
     1. clone the SCIONLab Ansible repo
     2. run ./master/ansible-inv-to-infrastructure.py < path/to/scionlab/ansible/inventories/viscon
     3. copy {src,dst}_addr.csv to webserver/infrastructure/ and worker_to_ssh.csv to master/.
   • Some details about those files:
     • The webserver needs src_addr.csv and dst_addr.csv. These list the SCION addresses of source (i.e. player) and destination (i.e. sink) machines, together with how many bytes people should be expected to transfer from/to that machine (the actual task will be the minimum of the two numbers).
     • Buildbot needs worker_to_ssh.csv (it actually only uses the first two columns, i.e. worker names and SCION addresses).
3. Create the Buildbot master
   • cd master; pipenv sync; pipenv run buildbot create-master buildbot-master
4. Create and start the Buildbot workers
   • An included helper script can automate worker management by running SSH commands on the machines listed in worker_to_ssh.csv: see master/manage_workers.py --help. It can also create local rather than remote workers for testing.
