Session Introduction

• Plan on spending 5 minutes in the beginning making sure everyone has fulfilled the prerequisites and has performed the advance preparation.
• If necessary, present a brief (~5 minutes) overview on goals, background information, and context. Make sure to link the slides to the session page.

Exercises

• make sure everyone has a working install of docker and has downloaded the necessary containers
  • Maybe we can use a loaner computer for people having problems?
• test docker using some standard containers (helloworld, bash, ...)
• start an interactive docker session using the tutorial container, and explore the structure of Offline
• Examine the directory tree and substructure
  • Look at the different kinds of source files: .cc, .inc, .fcl, _module.cc
  • Search for content (data products) in RecoDataProducts, MCDataProducts, etc
  • Search for algorithms (modules) that (say) build tracks, find clusters, identify background ,...
• setup a satellite release (or partial checkout?)
• explore scons script and run a simple build
• experiment with .build_opts
• look at content in /cvmfs
• look at setup.sh

Session Organization Guideline

• Encourage your attendees to ask questions if they are unsure what to do.
• You may or may not have session helpers, who have already performed the tutorial
• If someone finishes a step or exercise early, have them look around for neighbors that need help.
• If someone is stuck, have them raise their hand to get help.
