Puma doesn't start in ssl mode

[janwendt]

I have added this one to my puma.rb

ssl_bind '0.0.0.0', '3000', {
  key: 'config/ssl-certificate/my-server.key.pem',
  cert: 'config/ssl-certificate/my-server.crt.pem'
}

and rails s doesn't start puma in ssl mode.
puma -C config/puma.rb works just fine!!!

This is related to #24435 and puma/puma#939.

Here is the issue. Puma favors config you pass in directly over config in your puma.rb. For example if you have

port 3001

and you run

$ puma --port 5001

Then 5001 will win. Why does this matter? Rails allows you to run $ rails server -p 5001 however it also specifies a default port of 3000 when running $ rails server. Puma doesn't know the difference between the default passed in and an explicit user supplied argument. So it always uses what it thinks is the "passed in" argument which in this case would be using a port of 3000 even though it's only the default. This takes precedence over your connection config since all that method does is build a port to connect to:

      def ssl_bind(host, port, opts)
        o = [
          "cert=#{opts[:cert]}",
          "key=#{opts[:key]}"
        ]

        @options[:binds] << "ssl://#{host}:#{port}?#{o.join('&')}"
      end

It works with the $ puma command (btw it auto reads config/puma.rb no need to specifiy the config file) because there is no provided default port.

The answer is to not use the $ rails s command.

This problem is really weird. One of my rails apps reads the config file, and one does not.

@janwendt it worked for me using these versions:

• rails (5.0.1)
• puma (3.7.0)
