I'm studing Docker and i just created a Rails app following the guide here https://docs.docker.com/compose/rails/ , the image used in this guide use the PUMA as server APP. When i up my container the app is already published on WWW by myipnumber:3000.
So here is my doubt, how is possible to my app is published on WWW without a Web Server like NGINX/Apache since these are aparenttly not installed in my host or container? (maybe they are but i cant see).
Puma is a rack-compliant application server that handles HTTP requests for you.
You'll need a web server for production deployment (but it's a different story).

I want to know how to build a rails server and host an app on it locally. I know I can use heroku or aws but in the case of this app I can’t, the database should be hosted locally in the company for security reasons; they do not want to store their data on servers that are not theirs.
How do I start?
What are the main things to consider?
Do I host on heroku and link the local database to the site or do I host them all in the same place?
How much power does the machine need for around 10-20k users?
What OS should I use Ubuntu or what?
Would really appreciate if you have any tutorials or article links.
You can just use ngrok. It doesn't require any side server deployments.
So lately, I offer myself a Mac Mini which I want to use as a server (Websites, caching, Xcode Server (which is not working), VPN (which is not working), and stuff). Currently it is running macOS Sierra (10.12.4) with Server.app (5.3) installed. I've successfully enabled Websites & DNS service so my server is accessible from the outside. I have a trusted and valid SSL certificate.
The problem is...
...I don't know how to setup the server to be a production server for Ruby On Rails.
Want I want
To host a web app using Ruby On Rails on macOS server (www.example.com)
To know how to setup the server app to serve a web app
To host a Git repository for the web app code
I looked at the settings for Websites service in the Server app but I didn't find any options for other than PHP and Python.
What I know
My MacBook is already setup with Ruby 2.4 and Rails 5.0. I know how to install Rails for development purpose
Even if it's not straight-forward, post any help you have.
One of my guesses is that I could forward the port opened for the website without specifying a folder where the files are in the Server app.
I'd be pleased of you inlight in some way to achieve my goal.
I am pretty sure that you don't want to actually run production off of your mac mini. That said once you have your rails app running you can run rails s to run your server locally. If you want a production site you should look into either heroku or AWS elastic beanstalk for deployment.
We want to configure Apache to work with a Rails app. We want Apache to do load control. We cannot get them to work together. We are using MySQL for the database. If we could please have some type of instruction or tutorial to follow to be able to deploy our application in AWS-EC2, it will be greatly appreciated.
We have a domain and we want to have multiple Rails app running in the same domain. Each rails app seems to want to run in a different port. We do not want to expose port 80/443. Apache is managing the inbound request. My attempts to use the host file has not been successful.
I have two questions about rails server:
Do I have to start the server from within the application folder?
Is the server I started only for that application?
If they are true, this does not quite make sense to me, since why do I need to start multiple servers?
Or is there some kind of master configuration, so that one server can route to different applications? Is Capistrano for this purpose?
I'm going to assume you're talking about the rails server command, for running a local rails server to test your application, and that you're not talking about setting up a rails application on a remote server. Please mention if that is not the case.
Yes, you must execute rails server from within the root folder of your rails application.
Yes, the server you started is only for that application. It's a self-contained thing.
You should not need to start multiple servers. Even if you have multiple applications, you probably don't need to have more than one running at a time. So, you can shut down the rails server in one application (Ctrl-C) and then cd to your new application, and start a new rails server there with rails server.
If you do need to run two local rails applications at once, you can do so by running them on different ports. So, the first one, you can just execute rails server and it will make your site available at localhost:3000 (because port 3000 is the default port). The next one, you can specify a port other than 3000 - eg. rails server -p 3001 to get a rails app at localhost:3001.
Capistrano is for deploying your applications to a remote server, not for running them locally on your own computer. So, it is not relevant here. What you may be interested in is http://pow.cx/
Again, I've assumed you're talking about running your rails app locally on your own computer. If you're referring to deploying it to the internet on a server, then you can ignore this answer.
I'm able to run rails s through ssh successfully and see the app start up just as it does on my own machine but I'm unable to access the app from the web. The app is directly under the home folder and I have a symbolic link pointing from public_html to the public folder of my rails app, just as this tutorial explains. I even tried setting up a subdomain and every other step in the tutorial to no avail. Any help would be highly appreciated.
You need an application server like Phusion Passenger, Unicorn or puma to run a Ruby app in a production environment. Typically, you'll integrate the application server into a web server's (Apache, nginx) environment.
I don't know about your hoster, but if you have root access, then you can probably use any of these application servers.
The built-in server you start by running rails server is only meant for testing purposes on your local machine. It has not been made with security, performance, stability or any other production-environment criteria in mind.
