Flags

Name Shorthand Default Usage
allow-missing-template-keys true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.
dry-run false If true, only print the object that would be sent, without sending it.
generator poddisruptionbudget/v1beta1/v2 The name of the API generator to use.
max-unavailable The maximum number or percentage of unavailable pods this budget requires.
min-available The minimum number or percentage of available pods this budget requires.
no-headers false When using the default or custom-column output format, don’t print headers (default print headers).
output o Output format. One of: json|yaml|wide|name|custom-columns=…|custom-columns-file=…|go-template=…|go-template-file=…|jsonpath=…|jsonpath-file=… See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
output-version DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: ‘jobs.v1.batch/myjob’).
save-config false If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future.

selector A label selector to use for this budget. Only equality-based selector requirements are supported.
show-all a false When printing, show all resources (default hide terminated pods.)
show-labels false When printing, show all labels as the last column (default hide labels column)

template Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
