Kubectl config unset

I have a kubernetes config file with some user info, like this:

users:
- name: arn:aws:eks:eu-west-1:123456789012:cluster/cluster1
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args:
      - --region
      - eu-west-1
      - eks
      - get-token
      - --cluster-name
      - cluster1
      command: aws
      env:
      - name: AWS_PROFILE
        value: profile1
- name: arn:aws:eks:eu-west-1:210987654321:cluster/cluster2
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args:
      - --region
      - eu-west-1
      - eks
      - get-token
      - --cluster-name
      - cluster2
      command: aws
      env:
      - name: AWS_PROFILE
        value: profile2

I’d like to remove the env part from both users but I can’t find the way to do it with kubectl config unset.

For example, I can delete the full exec part from the user with name arn:aws:eks:eu-west-1:123456789012:cluster/cluster1 with:

kubectl config unset users.arn:aws:eks:eu-west-1:123456789012:cluster/cluster1.exec

users:
- name: arn:aws:eks:eu-west-1:123456789012:cluster/cluster1
  user: {}
- name: arn:aws:eks:eu-west-1:210987654321:cluster/cluster2
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args:
      - --region
      - eu-west-1
      - eks
      - get-token
      - --cluster-name
      - cluster2
      command: aws
      env:
      - name: AWS_PROFILE
        value: profile2

But if I try to delete only the env part with:

kubectl config unset users.arn:aws:eks:eu-west-1:123456789012:cluster/cluster1.exec.env

I get the following error message:

error: unable to parse one or more field values of users.arn:aws:eks:eu-west-1:123456789012:cluster/cluster1.exec.env

The source code for the unset command is at kubectl/unset.go at master · kubernetes/kubectl · GitHub but I’m not a Go guy and can’t guess the right syntax for the PROPERTY_NAME to delete just de env part.

Can someone give me a :raised_hand_with_fingers_splayed: here?
