synopsis: Perform a rolling update of the given ReplicationController.
description: |-
  Perform a rolling update of the given ReplicationController.

  Replaces the specified replication controller with a new replication controller by updating one pod at a time to use the
  new PodTemplate. The new-controller.json must specify the same namespace as the
  existing replication controller and overwrite at least one (common) label in its replicaSelector.
options:
- name: container
  usage: |
    Container name which will have its image upgraded. Only relevant when --image is specified, ignored otherwise. Required when using --image on a multi-container pod
- name: deployment-label-key
  default_value: deployment
  usage: |
    The key to use to differentiate between two different controllers, default 'deployment'.  Only relevant when --image is specified, ignored otherwise
- name: dry-run
  default_value: "false"

    If true, print out the changes that would be made, but don't actually make them.
- name: filename
  shorthand: f
  default_value: '[]'
  usage: |
    Filename or URL to file to use to create the new replication controller.
- name: image
  usage: |
    Image to use for upgrading the replication controller. Must be distinct from the existing image (either new image or new image tag).  Can not be used with --filename/-f
- name: include-extended-apis
  default_value: "true"
  usage: |
    If true, include definitions of new APIs via calls to the API server. [default true]
- name: no-headers
  default_value: "false"
  usage: When using the default output, don't print headers.
- name: output
  shorthand: o
  usage: |
    Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://releases.k8s.io/HEAD/docs/user-guide/jsonpath.md].
- name: output-version
  usage: |
    Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
- name: poll-interval
  default_value: 3s
  usage: |
    Time delay between polling for replication controller status after the update. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
- name: rollback
  default_value: "false"
  usage: |
    If true, this is a request to abort an existing rollout that is partially rolled out. It effectively reverses current and next and runs a rollout
- name: schema-cache-dir
  default_value: ~/.kube/schema
  usage: |
    If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'
- name: show-all
  shorthand: a
  default_value: "false"
  usage: |
    When printing, show all resources (default hide terminated pods.)
- name: show-labels
  default_value: "false"
  usage: |
    When printing, show all labels as the last column (default hide labels column)
- name: sort-by
  usage: |
    If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
- name: template
  usage: |
    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].
- name: timeout
  default_value: 5m0s
  usage: |
    Max time to wait for a replication controller to update before giving up. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
- name: update-period
  default_value: 1m0s
  usage: |
    Time to wait between updating pods. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
- name: validate
  default_value: "true"
  usage: |
    If true, use a schema to validate the input before sending it
inherited_options:
- name: alsologtostderr
  default_value: "false"
  usage: log to standard error as well as files
- name: api-version
  usage: |
    DEPRECATED: The API version to use when talking to the server
- name: as
  usage: Username to impersonate for the operation.
- name: certificate-authority
  usage: Path to a cert. file for the certificate authority.
- name: client-certificate
  usage: Path to a client certificate file for TLS.
- name: client-key
  usage: Path to a client key file for TLS.
- name: cluster
  usage: The name of the kubeconfig cluster to use
- name: context
  usage: The name of the kubeconfig context to use
- name: insecure-skip-tls-verify
  default_value: "false"
  usage: |
    If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
- name: kubeconfig
  usage: Path to the kubeconfig file to use for CLI requests.
- name: log-backtrace-at
  default_value: :0
  usage: when logging hits line file:N, emit a stack trace
- name: log-dir
  usage: If non-empty, write log files in this directory
- name: log-flush-frequency
  default_value: 5s
  usage: Maximum number of seconds between log flushes
- name: logtostderr
  default_value: "true"
  usage: log to standard error instead of files
- name: match-server-version
  default_value: "false"
  usage: Require server version to match client version
- name: namespace
  usage: If present, the namespace scope for this CLI request.
- name: password
  usage: Password for basic authentication to the API server.
- name: server
  shorthand: s
  usage: The address and port of the Kubernetes API server

example: |
  # Update pods of frontend-v1 using new replication controller data in frontend-v2.json.
  kubectl rolling-update frontend-v1 -f frontend-v2.json

  # Update pods of frontend-v1 using JSON data passed into stdin.
  cat frontend-v2.json | kubectl rolling-update frontend-v1 -f -

  # Update the pods of frontend-v1 to frontend-v2 by just changing the image, and switching the
  # name of the replication controller.
  kubectl rolling-update frontend-v1 frontend-v2 --image=image:v2

  # Update the pods of frontend by just changing the image, and keeping the old name.
  kubectl rolling-update frontend --image=image:v2

  # Abort and reverse an existing rollout in progress (from frontend-v1 to frontend-v2).
  kubectl rolling-update frontend-v1 frontend-v2 --rollback
