Hosted Apache Solr's Revamped Docker-based Architecture

I started Hosted Apache Solr almost 10 years ago, in late 2008, so I could more easily host Apache Solr search indexes for my Drupal websites. I realized I could also host search indexes for other Drupal websites too, if I added some basic account management features and a PayPal subscription plan—so I built a small subscription management service on top of my then-Drupal 6-based Midwestern Mac website and started selling a few Solr subscriptions.

Back then, the latest and greatest Solr version was 1.4, and now-popular automation tools like Chef and Ansible didn't even exist. So when a customer signed up for a new subscription, the pipeline for building and managing the customer's search index went like this:

Fixing ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY SSL error in Chrome

Recently, I was upgrading the infrastructure for Hosted Apache Solr, and as part of the upgrade, I jumped from Nginx 1.8.x to 1.10.x, which includes HTTP/2 support. I had previously used SPDY support in my server configuration to help the site run better/faster on modern browsers with SPDY support:

server
{
    listen 443 ssl spdy;
    server_name hostedapachesolr.com;
    ...
}

After the server upgrades, I was getting the following error on Nginx restarts:

nginx: [warn] invalid parameter "spdy": ngx_http_spdy_module was superseded by ngx_http_v2_module in /etc/nginx/conf.d/hostedapachesolr.conf:10

So I switched the configuration to use http2 instead of spdy on the listen line, and restarted nginx.

Everything worked great in Safari and FireFox, but when I tried loading the page in Chrome, I was greeted with the following error:
