Fix Localhost Binding for Safari

Safari does not automatically bind *.localhost domains to 127.0.0.1. To use Safari for local development and especially when using docker with SSL you will need to add the entries to your /etc/hosts file. Here is an example: 

sudo nano /etc/hosts

# add the following entries
127.0.0.1       mysite.localhost
127.0.0.1       somesubdomain.mysite.localhost
