Is there any simple deployment tool for rails app?

Hi I am new to RoR.

I am on a mission to deploy my SpreeCommerce store to my VPS. It looks
like
a simple task but I have been working on it for 3 days.

Installing Spree and running it on development mode is a piece of cake.
But
I have no experience on deploying the app and automating the service on
VPS.

Here is my plan:

  • Deploy it on a Puma web server using Nginx as a reverse proxy
    server.*

  • Use some auto deployment tool (such as Capistrano or Phusion
    Passenger) to deploy it as a service so I don’t need to monitor the
    server
    manually.*

What I have done:

installed Puma and run SpreeCommerce 3.0 on Puma web server,

Config Nginx to run my SpreeCommerce rails app on my VPS ip.

Now I need to use a deployment tool to deploy it as a service,

I have looked into Capistrano. I know it can do a lot of jobs, such as
data
migration and pulling source from a repository. But to be honest all I
want
is to deploy my
online store as a service on my VPS so I can start and stop it and run
it
at background. Capistrano is too much for me and the configuration looks
so
daunting.

Can I still find a simpler way to do what I need? Hope you can give me
some
suggestions. Thank you.

Best,

Aaron

OK now I know what I actually need. I just need a Puma daemon service. I
have found this

Hope it will help me. I will test it in the afternoon.
