Docker errors - Nginx keeps looking for files under /etc/nginx/html

Question

I have a seperate docker container setup with Lesencrypt (using nginx, nginx-gen, nginx-letsencrypt)

The Nginx and app containers are working fine but I see errors in Docker logs for Nginx.

I have the volumes for nginx docker at:

 - /srv/www/nginx-proxy/conf.d:/etc/nginx/conf.d
 - /srv/www/nginx-proxy/vhost.d:/etc/nginx/vhost.d
 - /srv/www/nginx-proxy/html:/usr/share/nginx/html
 - /srv/www/nginx-proxy/certs:/etc/nginx/certs:ro

I see a lot of docker errors in Nginx Docker logs Most of these errors are caused due to a missing files at /etc/nginx/html:

These are the same with other Docker applications that are deployed.

Say we have a Wordpress Docker deployed with volumes

- ./wordpress:/var/www/html

Or say we have a server block setup for external load balancer such as ALB/CloudFront/CloudFlare, this is important for us to mitigate docker errors for these external load balancers to failover to other servers in the event of a server failure.

I see errors for missing files at /etc/nginx/html/ like the below:

Below are the Nginx and sample webapp(foo.bar) server blocks that are created automatically by the Dockers:

server {
        server_name _; # This is just an invalid value which will never trigger on a real hostname.
        listen 80;
        access_log /var/log/nginx/access.log vhost;
        return 503;
}
server {
        server_name _; # This is just an invalid value which will never trigger on a real hostname.
        listen 443 ssl http2;
        access_log /var/log/nginx/access.log vhost;
        return 503;
        ssl_session_tickets off;
        ssl_certificate /etc/nginx/certs/default.crt;
        ssl_certificate_key /etc/nginx/certs/default.key;
}

server {
        server_name foo.bar;
        listen 80 ;
        access_log /var/log/nginx/access.log vhost;
        include /etc/nginx/vhost.d/default;
        location / {
                proxy_pass http://foo.bar;
        }
}
server {
        server_name foo.bar;
        listen 443 ssl http2 ;
        access_log /var/log/nginx/access.log vhost;
        return 500;
        ssl_certificate /etc/nginx/certs/default.crt;
        ssl_certificate_key /etc/nginx/certs/default.key;
}

Am I missing something or should we consider these errors normal?

Is there a way to get rid of these errors?

Hi Michael, the server blocks are added to the question. Thanks. — Harish Chennamsetty, Mar 14 '19 at 18:15
I know this is old... but I'm having the same exact issue today. Was this ever solved @HarishChennamsetty? — Drew, Jan 27 '22 at 20:40
