Kubernetes get command

kubectl get <resources>

isplay one or many resources.

Prints a table of the most important information about the specified resources. You can filter the
list using a label selector and the –selector flag. If the desired resource type is namespaced you
will only see results in your current namespace unless you pass –all-namespaces.

By specifying the output as ‘template’ and providing a Go template as the value of the –template
flag, you can filter the attributes of the fetched resources.

Use “kubectl api-resources” for a complete list of supported resources.

Examples:

kubectl get pods

kubectl get deployments

kubectl get services

kubectl get configmaps

kubectl get secrets

kubectl get ingress
