In order to start this project locally, you must run mysql first. You can choose how you want do it (install it locally and then run it or just run a mysql docker). Once this is done, then you'll have to create databases manually:
CREATE DATABASE IF NOT EXISTS ecommerce_write_model;
CREATE DATABASE IF NOT EXISTS ecommerce_read_model;
Finally, we are using default mysql user (root) & password (without password). If your mysql has a different user & password, just change it at application.yml configuration.
If you had any kind of problem running the project locally, you can contact us via github or in the codely.tv course ;) We'll fix the issue as soon as possible.
