Red Hat Summit8.2. Local access kubeconfig file
The local access kubeconfig file is written to /var/lib/microshift/resources/kubeadmin/kubeconfig. This kubeconfig file provides access to the API server by using localhost. Choose this file when you are connecting the node locally.
Example contents of kubeconfig for local access
clusters:
- cluster:
certificate-authority-data: <base64 CA>
server: https://localhost:6443
The localhost kubeconfig file can only be used from a client connecting to the API server from the same host. The certificates in the file do not work for remote connections.
8.2.1. Accessing the MicroShift node locally
Use the following procedure to access the MicroShift node locally by using a kubeconfig file.
Prerequisites
-
You installed OpenShift CLI (
oc).
Procedure
Optional: to create a
~/.kube/folder if your Red Hat Enterprise Linux (RHEL) machine does not have one, run the following command:$ mkdir -p ~/.kube/Copy the generated local access
kubeconfigfile to the~/.kube/directory by running the following command:$ sudo cat /var/lib/microshift/resources/kubeadmin/kubeconfig > ~/.kube/configUpdate the permissions on your
~/.kube/configfile by running the following command:$ chmod go-r ~/.kube/config
Verification
Verify that MicroShift is running by entering the following command:
$ oc get pods -AExample output
