For install nginx-plus package I should add certificate (https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-plus/#installing-nginx-plus-on-debian-and-ubuntu). I want create mirror repository, but I don't understand where I should add certificate for auth.
When configuring the remote repository in Artifactory which will be used to proxy the NginX Debian repository, you can add the SSL certificate in the Advanced Settings tab. Inside the Remote Authentication section you will find a field for setting the SSL/TLS certificate this repository should use for authentication to the remote resource for which it is a proxy.
