I’ve got a Flask app with nginx reverse proxy server in front of it. I have deployed my application on a Digital Ocean droplet. I created a user with root privileges and I’m using this user to run my application over HTTPS. I’ve been having problems with permissions for the .pem files located in the following path: /etc/letsencrypt/live/my-domain-name.com. What I do now is to copy those files to my project folder using a sudo command in the terminal and then in the nginx Dockerfile I copy them again to /etc/nginx and give this path in the configuration file. However, this is not ideal because I want my SSL certificate to be automatically renewed. I tried changing permissions from my root user using commands such as chown -R user:user/etc/letsencrypt but nothing worked. I get this error:
nginx: [emerg] BIO_new_file("/etc/letsencrypt/live/my-domain-name.com/fullchain.pem") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/my-domain-name.com/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
Any idea how I can fix this problem? I want to be able to access the .pem files using the /live/my-domain-name path and to be able to renew my cert when it expires without using the root user. Any help would be greatly appreciated. Thanks.
