Debian – Connecting to Mongodb Bi-connector remotely in docker

The simplest solution is to remove the index directive and not rely on explicit or implicit $uri/ redirects. For example:

server {
  listen 80;
  root /var/www;
  location /docs {
    try_files $uri $uri/index.html =404;
  }
}

This isn't identical behaviour as it avoids the redirect altogether. If you wanted a trailing slash redirect like the index module gives, then a more complex solution is required. For example:

server {
  listen 80;
  root /var/www;
  location /docs {
    try_files $uri @redirect;
  }
  location @redirect {
    if ($uri ~* ^(.+)/$) { rewrite ^ $uri/index.html last; }
    if (-d $document_root$uri) { return $scheme://$host:8080$uri/; }
    return 404;
  }
}

Problem was a 100% EBCAK. Turns out I set up the the initial SSH tunnel to the MySQL instance using these instructions which maps a port on my local machine to port 3306 on the Amazon RDS instance, whereas the MongoDB daemon (mongod) runs on the EC2 instnace. When setting up the SSH tunnel to the MongoDB instance I followed the instructions a little too closely and as result mapped port 12345 on my machine to port 27017 on the MySQL instance and not the EC2 instance running mongod.

Not surprisingly, updating the tunnel to connect to the EC2 instance and not to the RDS instance did the trick.
