NAME

kubectl expose - Take a replicated application and expose it as Kubernetes Service

SYNOPSIS

kubectl expose [OPTIONS]

DESCRIPTION

Take a replicated application and expose it as Kubernetes Service.

Looks up a replication controller or service 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.

OPTIONS

--container-port=""
    Synonym for --target-port

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

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

--generator="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'.

-h, --help=false
    help for expose

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

--name=""
    The name for the newly created object.

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

-o, --output=""
    Output format. One of: json|yaml|template|templatefile|wide.

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

--overrides=""
    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.

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

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

--public-ip=""
    Name of a public IP address to set for the service. The service will be assigned this IP in addition to its generated service IP.

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

--target-port=""
    Name or number for the port on the container that the service should direct traffic to. Optional.

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

--type=""
    Type for this service: ClusterIP, NodePort, or LoadBalancer. Default is 'ClusterIP' unless --create-external-load-balancer is specified.

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 key 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.

--v=0
    log level for V logs

--validate=false
    If true, use a schema to validate the input before sending it

--vmodule=
    comma-separated list of pattern=N settings for file-filtered logging

EXAMPLE

    // Creates a service for a replicated nginx, which serves on port 80 and connects to the containers on port 8000.
    $ kubectl expose rc nginx --port=80 --target-port=8000
    // Creates a second service based on the above service, exposing the container port 8443 as port 443 with the name "nginx-https"
    $ kubectl expose service nginx --port=443 --target-port=8443 --name=nginx-https
    // Create a service for a replicated streaming application on port 4100 balancing UDP traffic and named 'video-stream'.
    $ kubectl expose rc streamer --port=4100 --protocol=udp --name=video-stream
