.SH NAME
.PP
kubectl expose \- Take a replication controller, service or pod and expose it as a new Kubernetes Service


.SH SYNOPSIS
.PP
\fBkubectl expose\fP [OPTIONS]


.SH DESCRIPTION
.PP
Take a replication controller, service or pod and expose it as a new Kubernetes Service.

.PP
Looks up a replication controller, service or pod by name and uses the selector for that resource as the
selector for a new Service on the specified port. If no labels are specified, the new service will
re\-use the labels from the resource it exposes.


.SH OPTIONS
.PP
\fB\-\-container\-port\fP=""
    Synonym for \-\-target\-port

.PP
\fB\-\-create\-external\-load\-balancer\fP=false
    If true, create an external load balancer for this service (trumped by \-\-type). Implementation is cloud provider dependent. Default is 'false'.

.PP
\fB\-\-dry\-run\fP=false
    If true, only print the object that would be sent, without creating it.

.PP
\fB\-\-external\-ip\fP=""
    External IP address to set for the service. The service can be accessed by this IP in addition to its generated service IP.

.PP
\fB\-f\fP, \fB\-\-filename\fP=[]
    Filename, directory, or URL to a file identifying the resource to expose a service

.PP
\fB\-\-generator\fP="service/v2"
    The name of the API generator to use. There are 2 generators: 'service/v1' and 'service/v2'. The only difference between them is that service port in v1 is named 'default', while it is left unnamed in v2. Default is 'service/v2'.

.PP
\fB\-l\fP, \fB\-\-labels\fP=""
    Labels to apply to the service created by this call.

.PP
\fB\-\-load\-balancer\-ip\fP=""
    IP to assign to to the Load Balancer. If empty, an ephemeral IP will be created and used(cloud\-provider specific).

.PP
\fB\-\-name\fP=""
    The name for the newly created object.

.PP
\fB\-\-no\-headers\fP=false
    When using the default output, don't print headers.

.PP
\fB\-o\fP, \fB\-\-output\fP=""
    Output format. One of: json|yaml|wide|name|go\-template=...|go\-template\-file=...|jsonpath=...|jsonpath\-file=... See golang template [
\[la]http://golang.org/pkg/text/template/#pkg-overview\[ra]] and jsonpath template [
\[la]http://releases.k8s.io/HEAD/docs/user-guide/jsonpath.md\[ra]].

.PP
\fB\-\-output\-version\fP=""
    Output the formatted object with the given version (default api\-version).

.PP
\fB\-\-overrides\fP=""
    An inline JSON override for the generated object. If this is non\-empty, it is used to override the generated object. Requires that the object supply a valid apiVersion field.

.PP
\fB\-\-port\fP=\-1
    The port that the service should serve on. Copied from the resource being exposed, if unspecified

.PP
\fB\-\-protocol\fP="TCP"
    The network protocol for the service to be created. Default is 'tcp'.

.PP
\fB\-\-selector\fP=""
    A label selector to use for this service. If empty (the default) infer the selector from the replication controller.

.PP
\fB\-\-session\-affinity\fP=""
    If non\-empty, set the session affinity for the service to this; legal values: 'None', 'ClientIP'

.PP
\fB\-a\fP, \fB\-\-show\-all\fP=false
    When printing, show all resources (default hide terminated pods.)

.PP
\fB\-\-sort\-by\fP=""
    If non\-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. 'ObjectMeta.Name'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
