Summaries

Summarizing Resources

Motivation

Quickly summarizing a collection of Resources and their state.

Summarizing Resource State using a columnar format is the most common way to view cluster state when developing applications or triaging issues. The columnar view gives a compact summary of the most relevant information for a collection of Resources.

Get

The kubectl get reads Resources from the cluster and formats them as output. The examples in this chapter will query for Resources by providing Get the Resource Type as an argument. For more query options see Queries and Options.

Default

If no output format is specified, Get will print a default set of columns.

Note: Some columns may not directly map to fields on the Resource, but instead may be a summary of fields.

kubectl get deployments nginx

NAME      DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
nginx     1         1         1            0           5s

You can also use a number of options to query out and format the way the resources are displayed. Some of the commonly used options include:

• wide
• custom columns
• labels
• show labels
• show kind
