[Feature]: `grafana` dashboard available behind a versioned URL for user not using `helm` chart

[davinkevin]

Is there an existing issue already for this feature request/idea?

• [X] I have searched for an existing issue, and could not find anything. I believe this is a new feature request to be evaluated.

What problem is this feature going to solve? Why should it be added?

After migration of the Grafana dashboard to the chart, it's not possible anymore to download the dashboard using curl for a specific version

$ curl -qsL https://raw.githubusercontent.com/cloudnative-pg/cloudnative-pg/${VERSION}/docs/src/samples/monitoring/grafana-dashboard.json

It's something required if you don't base your installation on the chart, like I do.

Describe the solution you'd like

Because it's now part of the chart, a solution could be to git tag the chart with the cnpg version associated, so we can use the previous curl call, with just a different url.

If not possible, with a bit of duplication, a kustomize module could be provided for the monitoring feature and stored/versioned in the cnpg repository. This would match exactly the expectation of user of the cnpg.yaml file provided.

See the one I've created fyi: https://gitlab.com/davinkevin.fr/home-server/-/tree/cfc0f4786d719251deff493a02c310f2e28015e2/cnpg-system/base/components/monitoring

Describe alternatives you've considered

Because the chart repository doesn't have tag based on cnpg, I can't say if the dashboard I download is the one for my instance 🤷… and I have no other alternatives.

@davinkevin Is there a reason why you would need a specific version of the chart as it is very much backwards compatible.

[davinkevin]

"very much backward compatible", is it enough for prod use case?

If you assure it is backward compatible, yeah it's useless. But I know it's very complicated to do so. Having a versioned one could be simpler for you and your users

The Grafana dashboard so far has been provided as a sample in the documentation, and never officially supported. As the project grows, we're trying to elevate that, possibly with a separate project within the CloudNativePG organization. Would you be interested in helping?

[davinkevin]

Helping on this yes, but it really depends how much effort. I'm mainly a consumer of the grafana dashboard, nothing else.

The dashboard you just delivered in the Grafana system is, to me, the best solution because it's automatically versionned: https://grafana.com/grafana/dashboards/20417-cloudnativepg/?tab=revisions
