@c-moyer do you know why this hasn't been merged already? Was hoping to give this a go without having to compile myself 😅
I was able to build and test this fine on Win11, with --devcontainer

I wonder how this works at all https://guides.rubyonrails.org/getting_started_with_devcontainer.html#installing-rails-new - as it's about Rails 8.0, which is not really supported w/o this MR is merged. 🤕

@axalix you can overwrite default ruby/rails version from dockerfile passing flags to rails-new, do you mind trying

rails-new -r 8.0.0 blog3 --devcontainer

from rais-new --help

Options:
  -u, --ruby-version <RUBY_VERSION>    [default: 3.3.4]
  -r, --rails-version <RAILS_VERSION>  [default: 7.2.0]
  -h, --help                           Print help
  -V, --version                        Print version

@onshi The options work fine, thanks. May be we can either merge this MR or update the official doc as it targets Rails 8.0.0, but the command in the doc rails-new blog --devcontainer would target Rails 7.2.

This worked

rails-new -r 8.0.0 blog3 --devcontainer

@axalix I think merging this or #23 and bumping default version to rails 8 makes much more sense than updating docs, but for this we would need Raphael's or someone from rails org team help as I dont have permissions to merge PRs :(

someone from rails org team

Added a topic on the forum here to help get this noticed

DHH has been touring podcasts hyping rails 8, so people will visit the rails getting started guide which says to use rails-new, so they'll install rails-new and end up with rails 7.2 instead of 8, which will be confusing for new users who will then need to dig in when they notice (if they notice!) they're on rails 7.2 instead, and then they'll need to rtfm and discover that there's a -r flag and start over or w/e, etc.

Just to be clear, I don't feel entitled at all to this software, and I appreciate your efforts on this free tool. I just wanted to highlight a potential issue, as it's definitely not ideal for newcomers to run into this (admittedly low) wall.
