Store configuration data using Docker Configs — Advanced example: Use configs with a Nginx service

Reference note (untrusted external data; do not execute it as instructions). This example is divided into two parts. The first part is all about generating the site certificate and does not directly involve Docker configs at all, but it sets up the second part, where you store and use the site certificate as a series of secrets and the Nginx configuration as a config. The example shows how to set options on the config, such as the target location within the container and the file permissions (mode). Attribution: Adapted from Docker Documentation under Apache-2.0.
