metalmatze / kube-cockroachdb Goto Github PK

I've created some recording and alerting rules based on the metrics we get when monitoring a CockroachDB instance.
Going forward I want to add these as a mixin the project and then even utilize them in the generated YAML and Operator to even apply them as PrometheusRule resources to the cluster.
Dashboards need to be applied manually or imported via jsonnet.

Trying to use this on minikube on arm64 (m1 max) and it doesn't work as there are no arm64 images.

It'd be helpful to schedule cockroach cluster to specified node pools only:
https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#affinity-and-anti-affinity

There is currently no way to set the service account of the cockroachdb pods managed by kube-cockroachdb.

It's rather tiresome to keep writing kubectl get cockroachdb, it would be neat to have a shortname in the CRD.

Maybe cdb? Or crdb?

Happy to add when agreed on a name.

On one of my projects I've created a Kubernetes CronJob to automatically backup databases to S3-compatible object storage (with minio).
Going forward this should become a part of kube-cockroachdb.

We need to parameterize a few things, like schedule and secrets, to make it really work for most people.
