VictoriaMetrics doesn’t need any of that, the setup is trivial in the VM side, there is no configuration at all, you just pass the retention period in the docker command line, that’s it, in the HA side you use the config for influx v1 without org, bucket, token ok r password, see the link below.
Thanks to this thread I discovered VM while researching options for long term storage, and I got VM/grafana running in 10 minutes, it’s fantastic. All in a raspberry pi with a just-installed crucial x6 ssd. Also running frigate with a coral accelerator, all dockerized.
