Nomad: [question] Is it possible to make a job dependent of other (Maybe using Batch Service Type with constraints)?

[tiagoalves83]

I need to run a workflow of jobs.
Basically a workflow is a bunch of tasks that need to run in order and just before the previous task is done.
In jobspec I don't see any option to make a job or task to run just after the complete execution of other task/job (dependency).
I try to check if constraints could be applied based in other jobs/tasks, but I haven't found the answer.
So, my question is: Is it possible to run tasks in order, making sure that one task will run only if the previous task is done ? How can i achieve that ?

@tiagoalves83 We are going to support DAGs in the future so you will be able to run workflows with that. Currently the workflow orchestrator has to be built outside Nomad.

is there a published roadmap?
do you want the dag stuff internal rather than contributing good integration with something like airflow(might not be good fit, idk)?

is there a possible timeline to completing this requirement ?

@amit-handa It is at least 6+ months out.

This feels like it's a related issue and seems to be due for 0.10.X
