With the ever-increasing popularity of Docker Swarm, I would love to see Drone runners interacting with the Swarm API or Drone using the Swarm natively for example when deployed within a Swarm stack etc.
What I would like to do is to create services with Swarm mode replicated-jobs using Drone. Are there any works in development or future plans in the backlog?
For example, launch a service called ci-build that has several tasks (replicated-jobs) such as clone, frontend, backend, publish etc. Current Drone features such as parallel steps would stay the same. In this case, frontend and backend tasks can be executed at the same time while publish depends_on both.
The integration with Swarm would bring a lot of scalability, serviceability and portability benefits to Drone. This is just a simple use case I can think of right now but I am sure the community can benefit this integration in many different ways.
There already is an entry in the forum which is long forgotten since 2018 
Swarm runtime for drone
I also created a GitHub issue which can be tracked here: Provide (optional) Ability to Use Docker Swarm as the Container Orchestrator · Issue #3309 · harness/drone · GitHub
