Configure OOD in Kubernetes with Dex

I follow the simple one and I encountered this problem:

Failed to submit session with the following error:

error: error loading config file “/home/rocky95/.kube/config”: open /home/rocky95/.kube/config: permission denied

here I was modified the cluster.d/my_k8s_cluster.yml

v2:
metadata:
title: “My K8s Cluster”
login:
host: “172.16.1.38”
job:
adapter: “kubernetes”
config_file: “/home/rocky95/.kube/config”
cluster: “ood-prod”
context: “ood-prod”
bin: “/usr/bin/kubectl”
username_prefix: “prod-”
namespace_prefix: “user-”
all_namespaces: false
auto_supplemental_groups: false
server:
endpoint: “172.16.1.38:6443”
cert_authority_file: “/etc/kubernetes/pki/ca.crt”
auth:
type: “oidc”
mounts:
batch_connect:
ssh_allow: false

I try to change the chmod config for /home/rocky95/.kube/config from chmod 600, 666, or even 755 and it’s still has the same problem

I also use the
config_file: ~/.kube/config
and also encountered the same problem.

I also try to follow this previous discussion, follow the cluster configuration and can’t solve this problem.
