Docker test container
Docker image capable of reporting its own container ID in a web app. This is more useful than the default Docker hello-world image for demonstrating the effect of multiple containers created from the same image.
This container image was needed for Esri's training class on deploying ArcGIS Enterprise on Kubernetes. We needed a way to show students that a page was being served by a particular container when multiple containers were running. One thing I love about this project is that the underlying web application is written in an ancient version of PHP. I don't know anything about PHP, and that version won't be installed on any machine where the app needs to run. But by containerizing it, I can piggyback on somebody else's work and serve up a working app in any environment.
