After running docker-compose up I got the error kong_1 | nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

Can you please show me where I’m doing wrong?

Thank you!

Well 80 is a reserved port. I would look into binding to 8080 for easy way out, or run that command that lets you map a process to a reserved port:
