I came across an exception from Sinatra 2.0.0 beta 2 with Rails 5 deploying to Amazon Linux AMI v 2.1. 6. I posted the question in the Sinatra Github repro, but was asked to post it here.
Edit: I came across this with Elastic Beanstalk, but as @neal reports that this also happens with the deployment of Capistrano in EC2.
Following are the steps to reproduce the problem:
Add this line to the gemfile:
gem 'sinatra', '2.0.0.beta2'
Create a new Elastic Beanstalk web environment such as "64-bit Amazon Linux 2016.03 v2.1.6 running Ruby 2.3 (Puma)," a web server. Use all the defaults except resizing the instance on t2.small (there’s not enough memory to deploy for something less)
Add two new environment variables to the Elastic Beanstalk environment using the web console SECRET_KEY_BASE = (set the value for this) RAILS_ENV = production
Deploy the application in this new environment, for example, using the eb command-line tools.
- Deploy it again
- Tail logs through the Elastic Beanstalk console.
