The chart expects some configuration related to a valid Boinc account.
To use it with the LHC@home project (as an example), visit its homepage and create an account. Then check the section Account Keys under Account Information - this is the value to pass for accountKey in the chart values file.
If you wish to use another project such as SETI@home, make sure you also update the project field.
You can rely on the CERN repository setup if you wish, or else install the chart by fetching it locally first.
helm repo add cern https://s3-website.cern.ch/cern-charts
helm install cern/boincYou can choose which applications you want to run directly on the project preferences web page.
Note that if you choose to run ATLAS Simulation you need to uncomment the repositories defined under cvmfs in the values file.
