Converting ConfigMap Output into Environment Variables

Altering the perpetual process

All the examples we’ve seen so far are differing only in the source. The destination is always the same. No matter whether ConfigMap is created from a file, from a directory, from literal values, or from an environment file, it perpetually resulted in one or more files being injected into a container.

This time we’ll try something different. We’ll see how we can convert a ConfigMap into environment variables.
