1. Create rails app in a new folder Follow steps here: https://docs.docker.com/samples/rails/

• Create folder with app name
• Create Dockerfile, Gemfile, Gemfile.lock, entrypoint.sh, docker-compose.yml as per https://docs.docker.com/samples/rails/
• Change Gemfile to 7.0
• Change Dockerfile to Ruby 3.0.0
• Run docker-compose run --no-deps web rails new . --force -T --database=postgresql --api

2. Pull in boilerplate that contains React setup (/frontend), Nginx config (/config), tmp (/tmp) make sure this is empty though and replace docker-compose.yml. React setup contains:

• Vite server
• Redux toolkit
• React Router
• NOTE: May need to alter frontend Dockerfile to install vite globally RUN npm install -g vite
• NOTE: Make sure that node_modules is not copied over from frontend folder
• NOTE: May need to manually run $ dco run frontend npm install which will install packages on container

3. Copy rails files from rails app created in Step 1 to backend folder. Some notes:

• Copy .gitignore, /backend/.gitignore and /backend/.dockerignore files from boilerplate
• Remove docker-compose.yml from rails folder
• Copy config/database.yml from boilerplate (Make sure to replace db name)
• Update Dockerfile from boilerplate
• NOTE: You may have to remove the /tmp folder if you have db issues when creating the database
• NOTE: You'll have to namespace rails routes to api/v1 in order to view on NGINX server

Run the following

• $ dco build
• $ dco up

Make sure the following is working:

• http://localhost:4000/: This should show React frontend
• http://localhost:4000/: This should show Rails backend
• http://localhost:8080/: This should show React frontend on NGinx server
• http://localhost:8080/api: This should show Rails backend on NGinx server

4. Add MUI and fonts by running the following: dco run frontend npm install @mui/material @emotion/react @emotion/styled dco run frontend npm install @fontsource/roboto (Be sure to import fonts in entrypoint)

5. Add sidekiq

• Add gem "sidekiq" to Gemfile
• Update config/application.rb with config.active_job.queue_adapter = :sidekiq
• Add sidekiq initializer
• Add sidekiq routes
• Update docker-compose.yml

NOTE: The following events will require a docker re-build:

• Adding/removing gems from Gemfile
• Altering appRouter

dco build dco up
