I work at Grafana and did quite a bit of work on Tanka in the past, so yes.

Any particular libraries you use to generate TF-JSON from jsonnet?

I wrote a generator a little while ago that can create jsonnet libraries from the TF schemas: https://github.com/Duologic/soysonnet

Example lib here: https://github.com/Duologic/soysonnet-aws

I only needed it for AWS so I didn't spend more time on it.

Show HN: Jsonnet implementation in Jsonnet

I've written a Jsonnet interpreter in Jsonnet.A few years ago I wrote a code generator for Jsonnet (crdsonnet [1]) and found templating insufficient. This lead me to create a JSON Schema for the language along with a library[2] that can manifest the expressions reliably. I was unaware that this was an intermediate representation (in the world of interpreters). Fun fact: while cdrsonnet uses...

I'm interested in the code that processes the swagger/openapi into jsonnet, can you link to that?

Hit me up on the #jsonnet channel on Kubernetes Slack or the #tanka channel on Grafana Slack if you want to go a bit more in depth.

At Grafana Labs we're using jsonnet at scale, while being a powerful functional language it is also excellent for rendering JSON/YAML config. We have developed Tanka[0] to work with Kubernetes, for other purposes I can recommend this course[1] (authored by me).

I've bought them 2 years ago including a few spares, haven't replaced them since (not sure what 'vacuum' means in this context).

Re:Grafana Mimir – Horizontally scalable long-term storage for Prometheus on Wednesday March 30, 2022 @10:38AM (#30855808)
Last year I wrote a blog post about this exact question: Who watches the watchers?

The general takeaway is that you run a minimal prometheus/alertmanager setup that only scrapes the agents, then use a dead man switch-like system to ensure this pipeline keeps working.
