Upgrading AWS Beanstalk Ruby 2.2 environment to Ruby 2.3
Raw
Ruby upgrade on AWS EBS
Steps I did:
1. Launched a completely new environment on beanstalk running the ruby version that I need, 2.3 (in my case I needed an update from Ruby 2.2 to Ruby 2.3) - used the sample application for faster and easier launch.
2. SSH-ed into the new instance and installed all dependencies that my application needs (packages, dev tools etc.) - you can also do these in the .ebextensions directory
3. Created a custom AMI from the instance running ruby 2.3 with everything installed
4. Used the same command that Rohit posted but with some tweeks:
aws elasticbeanstalk update-environment --region "REGION" --environment-name "ENV_NAME" --solution-stack-name "64bit Amazon Linux 2018.03 v2.8.1 running Ruby 2.3 (Puma)" --option-settings Namespace=aws:autoscaling:launchconfiguration,OptionName=ImageId,Value="ami-
xxxxxxxx"
The AMI option-settings was key for me, as this helped me the AMI with ruby 2.3.7 installed to be used for launching the new instance on the existing environment.
Not to forget, I have also specified the ruby version "2.3.7" in my Gemfile and .ruby-version file in the app as well.
