Track Product Version vs Git Version for a Wrapped Service?

[naftulikay]

Let's say I'm running Redis but a custom Docker build of it, so FROM redis:latest but with customizations. My workloads are deployed in Kubernetes.

Right now, I'm labeling my pods like this:

tags.datadoghq.com/env=dev
tags.datadoghq.com/service=redis
tags.datadoghq.com/version=adc83b19e793491b1c6ea0fd8b46cd9f32e592fc

This is nice because then it's easy for me to locate the exact Git version that produced the image/deployment.

However, since the underlying version of Redis may change, it would be nice to be able to add metadata referencing the actual Redis version so that in Datadog, I can distinguish the difference between Redis (e.g. 8.2.1).

Is there a labeling strategy where I can expose the Redis version to Datadog so I can group deployments based on what actual version of Redis that they are running?

Should I instead be labeling the version as the Redis version and embed the Git commit in some other label? How do most customers deal with this issue?
