Kubernetes set environment variables depending on namespace

I want to set specific env variables depending on the namespace.

The goal is to have one config yaml file for different namespaces and set different env variables/config maps for dev, qa and prod depending on the namespace which the config file is applied to.

Afaik, kubernetes doesn't come with this capability out of the box.

There are two ways to get around this:

  1. Deploy a standard ConfigMap that contains everything any deployment needs. Make your app recognise the namespace and use the appropriate variable.
  2. Deploy a sidecar app that generates a namespace-specific ConfigMap from a template. This sidecar will need access to kube-apiserver to deploy new ConfigMap manifests automatically.
