Guidance Dockerize is a set of configuration files that allow you to dockerize applications for local development and beyond.
Setup The setup.sh script is used when you have a application that you want to dockerize. You run this and it copies the files from the application folders to your project application folders.
Update The update.sh script is used when you want to take the files from your project application and move them back to dockerize to contribute your changes.
