Practice Test - KubeConfig

Solutions to the practice test - kubeconfig

  • Look for the kube config file under /root/.kube

    ``` $ ls -l /root/.kube ```

  • Run the kubectl config view command and count the number of clusters

    ``` $ kubectl config view ```

  • Run the command kubectl config view and count the number of users

    ``` $ kubectl config view ```

  • How many contexts are defined in the default kubeconfig file?

    ``` $ kubectl config view ```

  • Run the command 'kubectl config view' and look for the user name.

    ``` $ kubectl config view ```

  • What is the name of the cluster configured in the default kubeconfig file?

    ``` $ kubectl config view ```

  • Run the command 'kubectl config view --kubeconfig my-kube-config'

    ``` $ kubectl config view --kubeconfig my-kube-config ```

  • How many contexts are configured in the 'my-kube-config' file?

    ``` $ kubectl config view --kubeconfig my-kube-config ```

  • What user is configured in the 'research' context?

    ``` $ kubectl config view --kubeconfig my-kube-config ```

  • What is the name of the client-certificate file configured for the 'aws-user'?

    ``` $ kubectl config view --kubeconfig my-kube-config ```

  • What is the current context set to in the 'my-kube-config' file?

    ``` $ kubectl config view --kubeconfig my-kube-config ```

  • Run the command kubectl config --kubeconfig=/root/my-kube-config use-context research

    ``` $ kubectl config --kubeconfig=/root/my-kube-config use-context research ```

  • Replace the contents in the default kubeconfig file with the content from my-kube-config file.

    ``` $ mv .kube/config .kube/config.bak $ cp /root/my-kube-config .kube/config ```

  • The path to certificate is incorrect in the kubeconfig file. Fix it. All users certificates are stored at /etc/kubernetes/pki/users

$ kubectl get pods master $ ls dev-user.crt dev-user.csr dev-user.key master $ vi /root/.kube/config master $ grep dev-user.crt /root/.kube/config client-certificate: /etc/kubernetes/pki/users/dev-user/dev-user.crt master $ pwd /etc/kubernetes/pki/users/dev-user master $ kubectl get pods No resources found in default namespace.
