i'm getting an error when running kubectl one one machine (windows)
the k8s cluster is running on CentOs 7 kubernetes cluster 1.7 master, worker
Here's my .kube\config
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: REDACTED
server: https://10.10.12.7:6443
name: kubernetes
contexts:
- context:
cluster: kubernetes
user: system:node:localhost.localdomain
name: system:node:localhost.localdomain@kubernetes
current-context: system:node:localhost.localdomain@kubernetes
kind: Config
preferences: {}
users:
- name: system:node:localhost.localdomain
user:
client-certificate-data: REDACTED
client-key-data: REDACTED
the cluster is built using kubeadm with the default certificates on the pki directory
kubectl unable to connect to server: x509: certificate signed by unknown authority
One more solution in case it helps anyone:
My scenario:
~/.kube/config
~/.kube/config
for server
is https://kubernetes.docker.internal:6443
Issue: kubectl
commands to this endpoint were going through the proxy, I figured it out after running kubectl --insecure-skip-tls-verify cluster-info dump
which displayed the proxy html error page.
Fix: just making sure that this URL doesn't go through the proxy, in my case in bash I used export no_proxy=$no_proxy,*.docker.internal
