Initial commit of Thanos that stores metrics results in object storage allowing for better querying, metric compaction, and smaller prometheus instances. The installation uses the kube-thanos project (https://github.com/thanos-io/kube-thanos), manifests generation uses the `Makefile`, with application using kustomize. As the upstream project using jsonnet for configuration, most configuration options are in the settings.jsonnet file. Changes to the settings, requires rerunning the `make manifests` to create the new manifests. Commit the results to the metacpan-k8s repository.
Initial commit of prometheus that collects and displays metrics, stores them in Thanos, and includes dashboards in Grafana. The installation uses the kube-prometheus project (https://github.com/prometheus-operator/kube-prometheus), manifests generation uses the `Makefile`, with application using kustomize. As the upstream project using jsonnet for configuration, most configuration options are in the settings.jsonnet file. Changes to the settings, requires rerunning the `make manifests` to create the new manifests. Commit the results to the metacpan-k8s repository.
Initial commit of Loki that collects log data and stores them in an object store, for display/querying in Grafana. The installation uses the Loki project (https://github.com/grafana/loki), manifests generation uses the `Makefile`, with application using kustomize. As the upstream project using helm for configuration, most configuration options are in the values.yaml file. Changes to the settings, requires rerunning the `make manifests` to create the new manifests. Commit the results to the metacpan-k8s repository.
Adding this configuration enables grafana to query loki to display logs.
Initial commit of Vector Agent that collects logs from running pods and forwards them to Loki. The installation uses the Vector project (https://github.com/vectordotdev/vector), manifests generation uses the `Makefile`, with application using kustomize. As the upstream project using helm for configuration, most configuration options are in the values.yaml file. Changes to the settings, requires rerunning the `make manifests` to create the new manifests. Commit the results to the metacpan-k8s repository.

Observability stack for MetaCPAN
This PR uses upstream projects to provide observability for MetaCPAN. With
these tools, we can monitor the health of the application and the
infrastructure it runs on. This is the initial implementation that provides
basic monitoring and log collection.
