How do I set permissions in Ubuntu so that all nested files in directories automatically get the permissions I need?

Question

Access rights

Hello. Please help me solve the problem. In ubuntu 14.04, the web server is deployed and the page is published. Every time I change something on this page and re-attach it to a folder, I have to give it rights and change its owner.
chmod -R 777 /folder/folder/
chown -R admin /folder/folder/
How can I avoid this? Thank you!
