Common Mistakes

Using numeric permissions like 777 or 644 which may be insecure or incorrect.

Using flags that remove permissions like -r.

💡 Hint

Common Mistakes

Moving kubectl to /usr/local/sbin which is for system admin binaries.

Using /bin or /usr/bin which may be reserved for system binaries.

The standard location for user binaries is /usr/local/bin, so kubectl is accessible system-wide.

4fill in blank

Fill both blanks to verify kubectl installation and check its version.

Kubernetes

kubectl [1] && kubectl [2] version --client

Drag options to blanks, or click blank then click option'

Bget

Cdescribe

Dconfig

Attempts:

💡 Hint

Common Mistakes

Using 'get' or 'describe' which are for resources, not version info.

Using 'config' which manages kubeconfig files.

The version command shows kubectl's version and confirms it is installed.

5fill in blank

hard

Fill all three blanks to set the kubeconfig environment variable and verify cluster info.

Kubernetes

export [1]=[2] && kubectl [3] nodes

Drag options to blanks, or click blank then click option'

Cget

Dset

💡 Hint

Common Mistakes

Using 'set' instead of 'get' for the kubectl command.

Using wrong environment variable names or paths.

Setting KUBECONFIG points kubectl to the config file. Then kubectl get nodes shows cluster details.
