kubectl:tldr:21733

The command "kubectl get all" is used to retrieve information about all resources in a Kubernetes cluster.

When you run this command, it will display a list of all the resources in the default namespace (if no namespace is specified). The "all" keyword is a shortcut for all possible resource types that are considered "displayable" in the current namespace.

The output of this command will include the resource names, types, and their current statuses. It gives a brief overview of different resource types, such as pods, services, deployments, replica sets, and more.

Here's an example of the output of "kubectl get all":

NAME                READY   STATUS    RESTARTS   AGE
pod/my-pod          1/1     Running   1          10m
service/my-service  1/1     Running   0          10m

In this example, it displays the name, readiness, status, restart count, and age of the pods and services in the cluster.

It's important to note that "kubectl get all" command doesn't actually retrieve all possible resources in the cluster, but rather a subset of resources that are considered "displayable" or commonly used. To list all resources, you can use specific resource types or retrieve information using "kubectl get --all-namespaces".
