Hey!
Yes, you can use Promscale for storing Prometheus data in Postgres or TimescaleDB. For using Promscale in kubernetes, you can either use Tobs (automatically manages Promscale, Prometheus, TimescaleDB installation), or use Promscale helm charts (see
this) or use Promscale docker image itself while creating a deployment.
Note: for methods other than Tobs, make sure you point the database host, port and other necessary info (like password, ssl-mode) in Promscale if you are using Postgres or TimescaleDB.
Let me know if you have any problem.
Thank you.
