nginx container reverse proxy to other containers on podman

Question

Can someone point me to a NGINX Reverse Proxy container how to for podman? Most of the docs I find are for docker. Ideally I would like Nginx to act as reverse proxy so I can have multiple contains on my host nginx would proxy to the proper container base based on url. Keep in mind this is for internal use to my private nework. I currently only have 1 contain but plan to add more.

For example I have a container for my home page home.xxx. I would like nginx to proxy to my home page home so I don't have to type home.foo.org:8081

Any help is appreciated.

If you have your application running at home.foo.org:8081, you can do the following:

1. create a folder nginx and cd into it
2. create a default config and a config for your app

cat << EOF > default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

}
EOF

cat << EOF > app.conf
server {
  listen 80;
  server_name home.foo.org;

  location / {
    proxy_pass http://<your_ip>:8081;
  }
}
EOF

3. start nginx: podman run --name=nginx -p 80:80 -v <your_path>/nginx:/etc/nginx/conf.d:Z -d docker.io/library/nginx

Voila, now you have application available on HTTP. Do note that if you want SSL/TLS you should look for port 443 and change accordingly.
