Setting limits on Prometheus Pod

[arunxls]

• might be a dup of Add resource request and limits to each pod in L5d namespace (including Helm chart) #4122

I'm looking for flags that we can set to limit prometheus memory usage. I looked at the values.yaml but couldn't find anything to specify this. Would love some pointers on how we can configure this at linkerd install.

Thanks!

It is definitely possible. If you're using the Helm chart the relevant section of the values file is right at the bottom.

In the docs for linkerd-viz, you can see these values that are configurable:

prometheus.resources.cpu.limit                 | string | nil 
prometheus.resources.cpu.request               | string | nil 
prometheus.resources.ephemeral-storage.limit   | string | "" 
prometheus.resources.ephemeral-storage.request | string | ""
prometheus.resources.memory.limit              | string | nil  
prometheus.resources.memory.request            | string | nil

In a values file that you're passing to the install, it would look like:

...

prometheus:
  resources:
    cpu:
      # -- Maximum amount of CPU units that the prometheus container can use
      limit:
      # -- Amount of CPU units that the prometheus container requests
      request:
    memory:
      # -- Maximum amount of memory that prometheus container can use
      limit:
      # -- Amount of memory that the prometheus container requests
      request:

That's perfect, thank you!
