Exposing local dockerised app using nginx docker container - docker

Question

I have a julia app which has been dockerized using below docker file. And,I am running this local app as docker container on port 8080. The goal is to expose this docker app (port 8080) to public using nginx docker container.
I have followed this tutorial: https://www.domysee.com/blogposts/reverse-proxy-nginx-docker-compose and based on the instructions I have created two files, docker-compose.yml and nginx.conf as shown below.
Dockerfile for the local-app:
FROM julia:1.6
RUN apt-get update && apt-get install -y gcc
ENV JULIA_PROJECT #.
WORKDIR /home
ENV VERSION 1
ADD . /home
EXPOSE 8080
ENTRYPOINT ["julia", "-JApp.so", "-t", "auto", "-L", "src/App.jl", "-e", "App.run()"]
Docker-Compose:
version: "3.9"
services:
nginx:
image: nginx:alpine
container_name: production_nginx
volumes:
- ./nginx.conf:/etc/nginx/nginx.conf
- .:/usr/share/nginx/html
- ./nginx/error.log:/etc/nginx/error_log.log
- ./nginx/cache/:/etc/nginx/cache
- /etc/letsencrypt/:/etc/letsencrypt/
ports:
- 8080:80
- 443:443
local-app:
image: local-app:latest
container_name: production-local-app
expose:
- "8080"
Nginx.conf:
events {
}
http {
error_log /etc/nginx/error_log.log warn;
client_max_body_size 20m;
proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;
server {
server_name app.local.hosting;
location /local-app {
proxy_pass http://localhost:8080;
rewrite ^/local-app(.*)$ $1 break;
}
listen 80;
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/app.local.hosting/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/app.local.hosting/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
}
}
However, running the docker-compose starts two containers, 1 app and 2 nginx, but nginx exits with some error. May I ask, what could be the potential cause of the service failure. Look forward to all the suggestions, thanks in advance!
Update:
Adding the output from terminal upon executing the docker-compose file:
user#user:~/Desktop/App$sudo docker-compose up
Starting production-local-app ... done
Starting production_nginx ... done
