Nginx can't access SSL certificates - docker

Question

Trying to set up an HTTPS server using NGINX and DOCKER. Keep getting the same error while checking nginx configuration file nginx -t:
2020/11/13 13:37:52 [emerg] 6#6: cannot load certificate "/etc/nginx/certs/cert.crt": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/nginx/certs/cert.crt','r') error:2006D080:BIO routines:BIO_new_file:no such file) nginx: [emerg] cannot load certificate "/etc/nginx/certs/cert.crt": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/nginx/certs/cert.crt','r') error:2006D080:BIO routines:BIO_new_file:no such file) nginx: configuration file /etc/nginx/nginx.conf test failed
Tried copying certs dir into etc/nginx in Dockerfile and it didn't work:
Dockerfile
FROM node:latest as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY ./ .
RUN npm run build
FROM nginx as production-stage
RUN mkdir /app
COPY --from=build-stage /app/dist /app
COPY certs /etc/nginx
COPY nginx.conf /etc/nginx/nginx.conf
RUN nginx -t
Tried setting up docker volumes as well and still the same error.
nginx.conf

worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
server_name test;
ssl_certificate certs/cert.crt;
ssl_certificate_key certs/cert.key;
location / {
root /app;
index index.html;
try_files $uri $uri/ /index.html;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
}
P.S. Permissions of the certs are set to 444
chmod -R 444 certs
