This is a simple utility for Kubernetes for aggregating several config maps into a single one.

A pattern that has emerged is to store configuration files in a config map and mount them into a Pod. Often times, applications can include all files in a directory.
A config map can be mounted as a directory, but you can't natively combine multiple config maps into a single directory. As I want to manage some config files - for proemthues for example - with the application (in helm charts, perhaps), I needed a utility to do this. Hence, configmap-aggregator

Heavily influenced by konfd

./configmap-aggregator

where target is the config map that will hold the aggregated data. The keys in the resulting config map will be in the form <namespace>-<name>-<key>.

You may limit the namespaces searched by passing in the --namespace=<namespace> flag. This can be used multiple times. By default, all namespaces are search.

You may also specify a label query, by passing the --selector=<key=value> flag.

Generally, run an instance of configmap-aggregator for each targeted config map. In the future, this may be driven by a third party resource.

Note: we assume you are running kubectl in proxy mode to handle authentication with Kubernetes.

It works, but is not well tested.
