Nginx Redirect to Docker Container

I made my personal server SSL encrypted, so that only port 443 is accessible to the outside world. However, in doing so, I locked my web apps from seeing the outside world.

The gist of it is that I have two Docker chains such that <domain>:2019 and <domain>:2020 are two separate web applications that are each served with Nginx containers, and output correctly on my local machine. I want to have <domain>:2019 output to example1.com and <domain>:2020 output to example2.com from using the host machine's Nginx service. How would I go about doing this?

[edit]

The Docker chains have respective Nginx containers that look like:

 nginx: container_name: domain_nginx build: context: ./nginx volumes: - static_volume:/usr/src/domain_django/static ports: - "2019:80" depends_on: - django

Where the Nginx container outputs to 127.0.0.1:2019. I want a user going to example1.com to see the 127.0.0.1:2019

just need to use the name of the container name / services since you are using docker-compose. Try adding this configuration to your container with nginx:

http { include /etc/nginx/mime.types; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; server { listen 80 default_server; listen [::]:80; server_name example1.com example2.com; return 301 } server { listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name example1.com; ssl_certificate ssl/fullchain1.pem; ssl_certificate_key ssl/privkey1.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; keepalive_timeout 70; location / { proxy_pass ###<-------HERE you can use webapp proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } server { listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name example2.com; ssl_certificate ssl/fullchain2.pem; ssl_certificate_key ssl/privkey2.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; keepalive_timeout 70; location / { proxy_pass ###<-------HERE you can use webapp proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
}

Example of old docker-compose

version: '2'
services: # webapp is the name that you can use inside the nginx configuration webapp: build: build volumes: - .:/home/noc/app ports: - 8000:8000 environment: - RECAPTCHA_SECRET_KEY=**** - RECAPTCHA_SITE_KEY=**** - DB_HOST=****** nginx: image: nginx:1.10.2 volumes: - ./static:/var/www/static - ./config/nginx.conf:/etc/nginx/nginx.conf - /etc/letsencrypt/archive/:/etc/nginx/ssl links: - webapp depends_on: - webapp ports: - 80:80 - 443:443 command: /bin/bash -c "nginx -g 'daemon off;'"
