How to Transfer SSL Certificate to my remote Server using Circleci

I am performing DevOps using Circleci and Docker.

I need SSL certificates to be uploaded on my remote server so that i can use it in Nginx conf file.

but there is no way to store files in Circleci and if I use env variables it’s gonna be a lot of problem because I can have more than one certificate so i can’t use env variables for that.

How can i upload my SSL Certificate to my Remote server.

I may have multiple SSL Certificate for different domain to be uploaded on my remote server.

I need the certificate to be auto-renew and it’s a certbot let’s encrypt certificate.

Can someone please help me in SSL Certificate setup on my remote server using DevOps.
