Nginx with TLS (Handel certs in Docker)

I use alot of nginx with tls. And almost ll of my docker are public. So how do i solve the tls issues.
Well i have done it like so in my docker file i generate ssl cert for nginx in a folder i called /etc/nginx/tls
Then when i use my ngix in dev i get the generated certs.


But in prod then i mount the volum from the host with the correct certs into my ngix in /etc/nginx/tls and now my nginx pick up the prod certs and use them.


FROM nginx
LABEL name="Hackathon"
LABEL vendor="Base"
#Setting up tls
RUN mkdir /etc/nginx/tls
WORKDIR /etc/nginx/tls
RUN openssl req \
-new \
-newkey rsa:4096 \
-days 365 \
-nodes \
-x509 \
-subj "/C=US/ST=Denial/L=Springfield/O=Dis/" \
-keyout nginx.key \
-out nginx.crt
#Adding config
ADD nginx.conf /etc/nginx/nginx.conf
CMD nginx -g "daemon off;"

my nginx config


#user nobody;
worker_processes 1;
events {
worker_connections 1024;
http {
include mime.types;
include sites-enabled/*.conf;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream web {
server web1:5000;
server web2:5000;
server web3:5000;
server web4:5000;
server { 
listen 80;
listen 443 ssl;
ssl_certificate /etc/nginx/tls/nginx.crt;
ssl_certificate_key /etc/nginx/tls/nginx.key;
ssl_trusted_certificate /etc/nginx/tls/ca-certs.pem;
location / {
proxy_pass http://web;
proxy_set_header Host \$http_host; # required for docker client's sake
proxy_set_header X-Real-IP \$remote_addr; # pass on real client's IP
proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto \$scheme;
proxy_read_timeout 900;

Then when I start my continer in prod i uses docker run -d -v /etc/tls/hosname:/etc/ngix/tls -t cars-lb
