Nginx on web container proxies to incorrect port on data container in local development environment

[eecavanna]

The Nginx server running on the web container is configured to proxy requests to port 8080 of the data container, as shown here:

nmdc-server/web/nginx.conf.template

Lines 37 to 40 in c0c7f14

	location /data/ {
	proxy_pass http://data:8080/;
	proxy_buffering off;
	}

However, the data container is configured to listen (on the Docker network) on port 80, not 8080. That is implicit as we are not overriding its default configuration:

nmdc-server/docker-compose.yml

Lines 5 to 8 in c0c7f14

	data:
	image: nginx

As a result, when trying to do a bulk download locally, the web container reports this error:

connect() failed (111: Connection refused) while connecting to upstream, [...], upstream: "http://172.21.0.2:8080/[...]

Task

The task here is to reconcile the two port numbers: either have the web container proxy to port 80, or have the data container listen on port 8080. Please keep in mind how changes made here will impact our production and development environments on Spin.

This is related to a longstanding issue of some networking-related information being hard-coded in the nmdc-server repo.

I first noticed this issue while working on #1536.
