before forking, create the following environment variables in Jenkins:
Example: wordpress.yourdomain.com
Note: When adding a stack that uses a new domain name, it's recommened to configure the DNS before deploying to avoid DNS caching issues on your local machine. This occurs when you attempt to go to a domain before the DNS for it has been configured. The unconfigured resolution will can get cached on your router or computer, which technically doesn't cause issues for anyone but you, but it is annoying!
Example: wordpress.yourdomain.com
Default: wordpress
Add new global credentials to jenkins of type user/password
with id wordpress-db-root-auth
user: root, password: generate a new password
Add new global credentials to jenkins of type user/password
with id wordpress-db-auth
user: choose a username, password: generate a new password
