Hi everyone,
I have deployed a Kubernetes cluster based on kubeadm and for the purpose of performing HorizontalPodAutoscaling based on the Custom Metrics, I have deployed prometheus-adpater through Helm.
Now, i want to edit the configuration for prometheus-adpater and because i am new to Helm, i don't know how to do this. So could you guid me how to edit the deployed helm charts?
I guess helm upgrade is that are you looking for.
This command upgrades a release to a specified version of a chart and/or updates chart values.
So if you have deployed prometheus-adapter, you can use command helm fetch
Download a chart from a repository and (optionally) unpack it in local directory
You will have all yamls, you can edit them and upgrade your current deployed chart via helm upgrade
I found an example, which should explain it to you more precisely.
You're trying to customize an installed chart. Please use this guide Customizing the Chart Before Installing.
The key parts:
There are two ways to pass configuration data during install:
--values(or-f): Specify a YAML file with overrides. This can be specified multiple times and the rightmost file will take precedence--set name=value: Specify overrides on the command line
