kube-prometheus example configuration

This repository holds an configuration example for kube-prometheus. It can be used to build Kubernetes manifests that will install the Prometheus Operator. The jsonnet sources can be found in the kube-prometheus contrib directory upstream.

Prerequisites

jsonnet and gojsontoyaml.

Build

$ ./build.sh

This will create a manifests/ directory with all resources to apply:

$ kubectl -f manifests/

Building manifests for an internal repository

It's possible to specify an image repository we'd like to use instead of upstream images:

./build.sh --tla-str repository=foo.com/organization

Mirroring public images to an internal repository

Because the image names and tags used by the prometheus operator are defined in code, I've written a bit of jsonnet outputting the docker commands necessary to mirror all images used by the operator to an internal repository:

$ jsonnet -S --tla-str repository=foo.com/organization sync-to-registry.jsonnet
