Service start order¶
When multiple services need to be started together, they’re started in order according to the before
and after
in the layer configuration. Pebble waits 1 second after starting each service to ensure the command doesn’t exit too quickly.
The before
option is a list of services that this service must start before (it may or may not requires
them, see Service dependencies). Or if it’s easier to specify this ordering the other way around, after
is a list of services that this service must start after.
Note
Currently, before
and after
are of limited usefulness, because Pebble only waits 1 second before moving on to start the next service, with no additional checks that the previous service is operating correctly.
If the configuration of before
and after
for the services results in a cycle, an error will be returned when the Pebble daemon starts (and the plan is loaded) or when a layer that causes a cycle is added.
