## kubectl rollout resume
|
||||
|
||||
Resume a paused resource
|
||||
|
||||
### Synopsis
|
||||
|
||||
|
||||
Resume a paused resource
|
||||
|
||||
Paused resources will not be reconciled by a controller. By resuming a
|
||||
resource, we allow it to be reconciled again.
|
||||
Currently only deployments support being resumed.
|
||||
|
||||
```
|
||||
kubectl rollout resume RESOURCE
|
||||
```
|
||||
|
||||
### Examples
|
||||
|
||||
```
|
||||
# Resume an already paused deployment
|
||||
$ kubectl rollout resume deployment/nginx
|
||||
```
|
||||
|
||||
### Options
|
||||
|
||||
```
|
||||
-f, --filename=[]: Filename, directory, or URL to a file identifying the resource to get from a server.
|
||||
```
|
||||
|
||||
### Options inherited from parent commands
|
||||
|
||||
```
|
||||
--alsologtostderr[=false]: log to standard error as well as files
|
||||
--api-version="": The API version to use when talking to the server
|
||||
--certificate-authority="": Path to a cert. file for the certificate authority.

||||
--client-certificate="": Path to a client certificate file for TLS.
|
||||
--client-key="": Path to a client key file for TLS.
|
||||
--cluster="": The name of the kubeconfig cluster to use
|
||||
--context="": The name of the kubeconfig context to use
|
||||
--insecure-skip-tls-verify[=false]: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
|
||||
--kubeconfig="": Path to the kubeconfig file to use for CLI requests.
|
||||
--log-backtrace-at=:0: when logging hits line file:N, emit a stack trace
|
||||
--log-dir="": If non-empty, write log files in this directory
|
||||
--log-flush-frequency=5s: Maximum number of seconds between log flushes
|
||||
--logtostderr[=true]: log to standard error instead of files
|
||||
--match-server-version[=false]: Require server version to match client version
|
||||
--namespace="": If present, the namespace scope for this CLI request.
|
||||
--password="": Password for basic authentication to the API server.
|
||||
-s, --server="": The address and port of the Kubernetes API server
|
||||
--stderrthreshold=2: logs at or above this threshold go to stderr
|
||||
--token="": Bearer token for authentication to the API server.
|
||||
--user="": The name of the kubeconfig user to use
|
||||
--username="": Username for basic authentication to the API server.
