docker nginx - 404 not found - docker

Question

I followed these steps to setup nginx in docker at my server:
I create a nginx/ folder and put all the docker-compose.yml and conf.d/ with conf.d/default.conf accordingly.
docker-compose.yml:
version: "3.8"
services:
web:
image: nginx:latest
restart: always
volumes:
- ./public:/var/www/html
- ./conf.d:/etc/nginx/conf.d
- ./certbot/conf:/etc/nginx/ssl
- ./certbot/data:/var/www/certbot
ports:
- 80:80
- 443:443
certbot:
image: certbot/certbot:latest
command: certonly --webroot --webroot-path=/var/www/certbot --email abc#xyz.com --agree-tos --no-eff-email -d example.com -d www.example.com
volumes:
- ./certbot/conf:/etc/letsencrypt
- ./certbot/logs:/var/log/letsencrypt
- ./certbot/data:/var/www/certbot
and my cond.f/default.conf:
server {
listen [::]:80;
listen 80;
server_name example.com www.example.com;
location ~ /.well-known/acme-challenge {
allow all;
root /var/www/certbot;
}
# redirect http to https www
return 301 https://www.example.com$request_uri;
}
server {
listen [::]:443 ssl http2;
listen 443 ssl http2;
server_name example.com;
# SSL code
ssl_certificate /etc/nginx/ssl/live/example.com/fullchain.pem;
ssl_certificate_key /etc/nginx/ssl/live/example.com/privkey.pem;
root /var/www/html;
location / {
index index.html;
}
return 301 https://www.example.com$request_uri;
}
server {
listen [::]:443 ssl http2;
listen 443 ssl http2;
server_name www.example.com;
# SSL code
ssl_certificate /etc/nginx/ssl/live/example.com/fullchain.pem;
ssl_certificate_key /etc/nginx/ssl/live/example.com/privkey.pem;
root /var/www/html/example/public;
location / {
index index.html;
}
}
I am sure the SSL is working because I can access https://example.com with no problem.
But I always get 404 not found.
I do have a public/ folder in nginx/ folder with index.html. But somehow I always get 404.
I am using Ubuntu 20.
How can I resolve this?

Answer 1

Ok, after #Amin's comments, I read carefully on my config file, and found out that with all the rerouting of the port 80 to port 443, the root folder actually change to /var/www/html/example/public. so I just have to change my docker-compose volume binding from:
volumes:
- ./public:/var/www/html
to
volumes:
- ./public:/var/www/html/example/public
Now it works.
