Yes that is what they call service deploy.
If Swarmpit doesn't satisfy you on deployment you can use Apollo or command-line. It's all up to you.
Swarmpit is like having a kubernetes interface without the overbloat of Kubernetes. If Swarmpit evolves in the future it will not makes sense the Kubernetes.
I am almost finishing a swarm only setup in 512 MB of free RAM. For Kubernetes you need at least 4 GB.
