Here is my use-case. I have a long running server that is started by upstart. This server needs to be initialized first (populate tables in a db). This should only happen once in the life of the service (and again on migration), so can't be tied to a start/stop action.

How can I set this up in upstart? Can I set this up without having "start myservice-init; start myservice" ?

Is there a way to check from sh whether the db population is needed? If so you can have it 

start on starting myservice
task
pre-start script
    dbinitneeded || { stop; exit 0; }
end script
# init the db here with a script or exec

  • We want the setup to be explicit, so trying to figure out if a migration is needed is not something we can do. – ekaqu Jun 27 '14 at 22:06
  • Then just skip upstart entirely. Make it a little helper script, and exec it when needed. – CameronNemo Jun 27 '14 at 22:07
