helm not installing metrics-server
hi,
i'm trying to install metrics-server using helm, i'm following the official linode video tutorial, which uses this helm command
helm upgrade --install metrics-server bitnami/metrics-server \
--create-namespace --namespace metrics-server \
--set apiService.create=true \
--set extraArgs.kubelet-insecure-tls=true \
--set extraArgs.kubelet-preferred-address-types=InternalIP
unfortunatly it is throwing this error
coalesce.go:175: warning: skipped value for metrics-server.extraArgs: Not a table.
coalesce.go:175: warning: skipped value for metrics-server.extraArgs: Not a table.
Error: INSTALLATION FAILED: YAML parse error on metrics-server/templates/deployment.yaml: error converting YAML to JSON: yaml: line 57: did not find expected '-' indicator
can someone help with this,
thanx

I ran into the same problem. Looks like the helm chart changed. This worked for me:
helm upgrade --install metrics-server bitnami/metrics-server \
--create-namespace --namespace metrics-server \
--set apiService.create=true \
--set --extraArgs.kubelet-insecure-tls=true \
--set --extraArgs.kubelet-preferred-address-types=InternalIP
Looks like it changed in April 2022 from a map/table to a list (github).
I'm using the following values.yaml
apiService:
create: true
extraArgs:
- --kubelet-preferred-address-types=InternalIP
- --kubelet-insecure-tls
namespaceOverride: <NAMESPACE>
so that pods Args are set like so:
Args:
--secure-port=8443
--kubelet-preferred-address-types=InternalIP
--kubelet-insecure-tls
edit: change extraArgs in values.yaml to list of multiple strings
