Synopsis Roll back to a previous rollout. kubectl rollout undo (TYPE NAME | TYPE/NAME) [flags] Examples # Roll back to the previous deployment kubectl rollout undo deployment/abc # Roll back to daemonset revision 3 kubectl rollout undo daemonset/abc --to-revision=3 # Roll back to the previous deployment with dry-run kubectl rollout undo --dry-run=server deployment/abc Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

A ServiceAccount provides an identity for processes that run in a Pod. A process inside a Pod can use the identity of its associated service account to authenticate to the cluster's API server. For an introduction to service accounts, read configure service accounts. This task guide explains some of the concepts behind ServiceAccounts. The guide also explains how to obtain or revoke tokens that represent ServiceAccounts, and how to (optionally) bind a ServiceAccount's validity to the lifetime of an API object.

Details of the metric data that Kubernetes components export.

Note: This section links to third party projects that provide functionality required by Kubernetes. The Kubernetes project authors aren't responsible for these projects, which are listed alphabetically. To add a project to this list, read the content guide before submitting a change. More information. Many features rely on specific kernel functionalities and have minimum kernel version requirements. However, relying solely on kernel version numbers may not be sufficient for certain operating system distributions, as maintainers for distributions such as RHEL, Ubuntu and SUSE often backport selected features to older kernel releases (retaining the older kernel version).

Synopsis Create a LoadBalancer service with the specified name. kubectl create service loadbalancer NAME [--tcp=port:targetPort] [--dry-run=server|client|none] Examples # Create a new LoadBalancer service named my-lbs kubectl create service loadbalancer my-lbs --tcp=5678:8080 Options --allow-missing-template-keys     Default: 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 string[="unchanged"]     Default: "none" Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it.

Synopsis Set an individual value in a kubeconfig file. PROPERTY_NAME is a dot delimited name where each token represents either an attribute name or a map key. Map keys may not contain dots. PROPERTY_VALUE is the new value you want to set. Binary fields such as 'certificate-authority-data' expect a base64 encoded string unless the --set-raw-bytes flag is used. Specifying an attribute name that already exists will merge new fields on top of existing values.

Synopsis Create a config map based on a file, directory, or specified literal value. A single config map may package one or more key/value pairs. When creating a config map based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key, you may specify an alternate key. When creating a config map based on a directory, each file whose basename is a valid key in the directory will be packaged into the config map.
