Docs feedback: https://grafana.com/docs/loki/latest/setup/size/ is COMPLETELY broken

[simonfelding]

Hi Grafana
The values output here are completely broken and cause the deployment to fail with very bad error messages. Please take the link down or fix the output.

It produces the following output (as an example):

loki:
  authenabled: false
read:
  replicas: 9
  resources:
    requests:
      cpu: 3
      memory: 6
    limits:
      cpu: 3
      memory: 8
write:
  replicas: 4
  resources:
    requests:
      cpu: 1
      memory: 6
    limits:
      cpu: 2
      memory: 12

Problems:

1. It returns a file that does not end with yaml.
2. The output is not complete: You need to add more to get it working.
3. EXTREMELY BAD: The resources do not have units. This causes Kubernetes to break, as it assumes the units are very small.

It results in errors like
Warning FailedMount 18m kubelet MountVolume.SetUp failed for volume "kube-api-access-fl7vf" : write /var/lib/kubelet/pods/ed8cd4f9-ad9f-448a-a2e9-7891dfff649a/volumes/kubernetes.io~projected/kube-api-access-fl7vf/..2024_04_15_13_43_31.1659629596/ca.crt: no space left on device

Because Kubernetes uses the memory limits for the projected volume too.

@simonfelding, thanks for the feedback, someone also reported a different issue last Friday with the values that were being generated, and after some discussion with the Engineering team and leadership, we've decided to pull the sizing calculator for the time being. See #12598.

@JStickler
Hi, do we have any updates on the calculator? It appears to have issues with the units or formulas. I want to determine how much CPU and disk space.... my system requires, but I can't find any information

[JStickler]

The calculator is probably not going to be republished. The engineering team does not have the cycles to update it.

Thank you for your response
