I was trying out the Tectonic Kubernetes sandbox setup and according to their documentation:
https://coreos.com/tectonic/docs/latest/tutorials/first-app.html
I did download the kubectl and the corresponding kube-config files, but when I tried to get the namespaces using the following command:
kubectl get namespacesI get the following error:
The connection to the server localhost:8080 was refused - did you specify the right host or port?What is this? From where is it picking up this port locahost:8080?
EDIT:
Joe-MacBook-Pro:~ joe$ kubectl config get-contexts
CURRENT NAME CLUSTER AUTHINFO NAMESPACE
Joe-MacBook-Pro:~ joe$I'm lacking some details on your setup, but the problem is basically clear - you're not connected to the cluster.
You should have a kubeconfig file containing the cluster connection information i.e. the context, I assume if you run kubectl config view you'll get nothing.
I'm on windows using git bash, if I run the same command I get:
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: REDACTED
server: https://platform-svc-integration.net
name: svc-integration
contexts:
- context:
cluster: svc-integration
user: svc-integration-admin
name: svc-integration-system
current-context: svc-integration-system
kind: Config
preferences: {}
users:
- name: svc-integration-admin
user:
client-certificate: <path>/admin/admin.crt
client-key: <path>/admin/admin.keybasically what I'm trying to say is you need to configure your context, start by doing kubectl config --help to list your options, it's pretty straight forward but if don't manage just refer to the documentation.
