Creating Let's Encrypt Certificate & Certbot Within Docker Image

I have a Vue.js application that runs with Nginx in a docker image. I have followed some tutorials but none of them was helpful for my case to apply Let's Encrypt certification. How can I create a certificate within my docker file with my configuration?

Dockerfile:

FROM alpine:3.7

RUN apk add --update nginx nodejs

RUN mkdir -p /tmp/nginx/web
RUN mkdir -p /var/log/nginx
RUN mkdir -p /var/www/html

COPY nginx_config/nginx.conf /etc/nginx/nginx.conf
COPY nginx_config/default.conf /etc/nginx/conf.d/default.conf

WORKDIR /tmp/nginx/web

COPY . .

RUN npm install

RUN npm run build

RUN cp -r dist/* /var/www/html

RUN chown nginx:nginx /var/www/html

CMD ["nginx", "-g", "daemon off;"]

nginx_config folder:

default.conf:

server {
  location / {
      root /var/www/html;
      try_files $uri $uri/ /index.html;
  }
}

nginx.conf:

user  nginx;
worker_processes  1;

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

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    sendfile        off;

    keepalive_timeout  60;

    gzip  on;
    gzip_static on;
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_proxied  any;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_buffers 16 8k;
    gzip_http_version 1.1;

    include /etc/nginx/conf.d/*.conf;
}
