I would nest the DynamicSupervisor under another Supervisor with the strategy :rest_for_one and also add a setup Task after the DynamicSupervisor in that supervisor.

Supervisor(strategy: :rest_for_one)
  |----> DynamicSupervisor
  |----> SetupTask / GenServer

If your DynamicSupervisor crash it will be detected by the Supervisor.

  • It will kill the SetupTask / GenServer
  • restart DynamicSupervisor
  • restart your SetupTask / GenServer
