Nginx proxy_pass returns 404, where is error in http.conf?

Question

Nginx

on localhost:3000 raised react
on localhost:5090 raised API
on GET requests answered

decided to try to make http proxying

made http.conf

server {

    listen 80;

    server_name localhost;

        access_log  /var/log/nginx/localhost_access.log main;
        error_log /var/log/nginx/localhost_error.log warn;

    location /nginx_status {
                stub_status on;
                allow 127.0.0.1;
                deny all;
        }

    location /service {
        proxy_pass http://service1:5090;
        # Do not change this
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

    location /react {
        proxy_pass http://localhost:3000;
        # Do not change this
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

}

service1:5090 ; running in a container and accessible from the docker network by name and by localhost:5090

running under the feet of the axis npm start building a

docker image

FROM nginx:1.15.8

#change timezone on Moskow
ENV TZ=Europe/Moscow
RUN apt-get update && apt-get install -yy tzdata
RUN cp /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apt-get install -yy telnet iputils-ping curl

COPY conf.d/* /etc/nginx/conf.d/http/
COPY nginx.conf /etc/nginx/nginx.conf

after building and raising the container, I make a GET request to localhost / react
nginx returns a 404 error
in the logs

2022/02/08 21:25:59 [error] 7#7: *1 open() "/usr/share/nginx/html/react" failed (2: No such file or directory), client: 172.21.0.1, server: localhost, request: "GET /react HTTP/1.1", host: "localhost"

what's wrong?

Answer 1

The problem here is
COPY conf.d/* /etc/nginx/conf.d/http/
COPY nginx.conf /etc/nginx/nginx.conf
the first command replaces the contents of the http folder and there lay everything copied from conf.d
the second command replaces everything in the nginx folder with nginx.conf. Those. the first command does nothing. Or rather, the second kills everything that the first does.
