Fig / Docker-Compose-like JSON to feed into Mesosphere/Marathon to setup Multi-Tier Application

Question

Does anyone know if it is possible to setup a JSON file to feed into Mesosphere/Marathon to deploy multi-tier application with application dependency? Something along the lines of fig or docker compose when there is one yaml file describing applications to deploy and their dependency and etc ?

Thanks!!

Yes and this is a very timely question since I'm putting together a walkthrough on this, as we speak ;) for the time being you might want to check out github.com/mhausenblas/ntil which goes a bit in this direction. – Cohette

Yes, it's possible, see Application Deployments. I'm in the process of extending the Marathon doc to make this even clearer. Will provide updates here as well.

Thank you! ETA: next couple of days. – Cohette

Mike, yet again, thanks for all the work. Small question: the Application Deployment section where you have a sample syntax for the application group: is it supposed to go against DCOS (i.e., "dcos marathon app add test.json") or just feed it to marathon directly via API call ("cat test.json | http http:\\<>:8080...etc) ? Because for "dcos marathon app add..." it is complaining on: "Error: Additional properties are not allowed ('groups' was unexpected)" – Thresathresh

It's a (current) CLI limitation, yes so please use directly the HTTP API for now, sorry. – Cohette
