Setting up Rails for the first time with all the dependencies necessary can be daunting for beginners. Docked Rails uses a Rails CLI Docker image to make it much easier, requiring only Docker to be installed.
First install Docker (and WSL on Windows). Then copy'n'paste into your terminal:
docker volume create ruby-bundle-cache
alias rails='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle ghcr.io/rails/cli'
alias rails-server='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle -p 3000:3000 ghcr.io/rails/cli server -b 0.0.0.0'
alias rails-dev='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle -p 3000:3000 --entrypoint bin/dev ghcr.io/rails/cli'
alias bundle='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle --entrypoint bundle ghcr.io/rails/cli'
alias rake='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle --entrypoint rake ghcr.io/rails/cli'
alias yarn='docker run --rm -it -v $PWD:/rails -v ruby-bundle-cache:/bundle --entrypoint yarn ghcr.io/rails/cli'Then create your Rails app:
rails new weblog
cd weblog
rails generate scaffold post title:string body:text
rails db:migrate
rails-serverThat's it! You're running Rails on http://localhost:3000/posts.
