Changes

• Node: Improve the Node.js installation process to ensure the correct version is installed.
• database.yml: Updated to use environment variables. (Replaced by a copy in staging/production via the Capistrano deploy.)
• storage.yml: Updated the ENV name to align with DevOps.
• puma.rb: Updated to the latest Rails 8 copy.
• Dockerfile: Optimised the size from 4GB down to 2.4GB
• deploy/: Added a folder containing its own Gemfile and .ruby-version to pin the Ruby and Kamal versions for deployment.
• Kamal configs: Added Kamal configuration files.
• Kamal pre-build hook: Enabled the pre-build hook in Kamal.
• Sidekiq: Admin page password was previously managed via Nginx and .htaccess; moved to Rails credentials since this is application-level configuration.
• Removed ALLOWED_HOSTS logic in staging/production environment files. I believe that just for development.

Notes

• Dockerfile: Need hardcore --platform=linux/amd64 for chromium installed by puppeteer.
• Dockerfile.deploy has been tested locally in production mode.
• Environments secrets such as DB credentials, have been extracted from the existing server and added to the project’s GitHub Environments.
• This project connect to 2 databases. The ENV for database is special.
• Assets were previously served by Nginx; they’re now served by Puma. The RAILS_SERVE_STATIC_FILES environment variable has been added in config/deploy.yml.
• The RAILS_LOG_TO_STDOUT environment variable has also been added in config/deploy.yml so that logs are written to stdout.

TODO

• Remove Capistrano (not done yet).
• Finalise staging and production server addresses (TBC).
• Migrate the staging/production local files?
