carinamarina/try-rails repository overview

⁠Try Rails on Carina

This is a sample Rails application which runs on Carina and is backed by a MySQL database hosted on the Rackspace Cloud Database service.

1. Create a MySQL database in the IAD region in the Rackspace Cloud Control Panel. Note the host name, and credentials as it will be needed in the next step.

2. Run the carinamarina/try-rails container. Update the DATABASE_URL environment variable with your database connection details.

   docker run --name rails \
   --env DATABASE_URL="mysql://username:password@host/dbname" \
   --detach \
   --publish-all \
   carinamarina/try-rails
   

   Copy

3. Identity the port where the rails application was published. In the example below, the port is 32800.

   $ docker port rails
   3000/tcp -> 172.99.65.237:32800
   

   Copy

4. Open http://<dockerHost>:<containerPort>, for example http://172.99.65.237:32800⁠. You should see the Powered By Carina badge if the database connection was successful.
