Configuration concept

Status Quo:

For historical reasons (HealthMonitor used to be a separate daemon process), the LaunchManager currently loads multiple different configuration files:

• The Launch Management configuration containing the information about executables, sandbox, process groups
• The Health Management configuration containing the supervisions per process. Only the Alive Supervision configuration will be required from now on, though currently there is also Deadline, Logical, RecoveryActions, aggregations of supervisions
• The (optional) HealthMangement daemon config configuring the watchdog connection and internal buffer sizes

New Configuration Concept

• The currently different configuration files shall be merged into one consistent configuration format
• The format shall be defined with usability in mind, as the user is manually writing this json file
• The format shall be discussed and agreed in the lifecycle group

In the lifecycle meeting on 8th January we also discussed that:

• The configuration format shall be based on configuring RunTargets (rather than ProcessGroups)
• For the start, we stay with a single configuration file containing all process information. In the future this may get broken up into a single file per process
