SSL 证书 getaddrinfo：名称或服务未知（SocketError）Rails-4.2.0

Question

I have Rails 4.2.0 application with ruby version 2.2.0. I have a requirement where I need to create an SSL certificate for the test environment.

To set-up an SSL certificate I followed the below steps:

step-1: brew install mkcert

step-2: Added entry on /etc/hosts for the localhost domain ie 127.0.0.1 localhost.application_name

step-3: Created the key and certificate files for domain which I created by mkcert localhost.application_name

step-4: Then move those certificate files into the config\ssl folder

step-5: And then I start my rails server like bundle exec rails server -p 3000 -b 'ssl://127.0.0.1:3000?key=config/ssl/localhost.application_name-key.pem&cert=config/ssl/localhost.application_name.pem'

When I run the rails s with the below command I am facing an error 'getaddrinfo': getaddrinfo: Name or service not known (SocketError)

For more clarity, I am attaching the screenshot after rails s execute.

I already tried a lot of solution which is being already present in StackOverflow but no luck as of now. Any help will be appreciated!

Note: I have rails application setup with Docker

Answer 1

Binding syntax you provided (with ssl:// scheme) is used with puma application server.

WEBrick , which was the default application server with Rails 4.x, doesn't support this binding scheme.

So you can jump to puma by simply adding to Gemfile

gem 'puma'

and then run

bundle install

Then you'll be able to start your app as you're used to.
