NAMEoc expose − Expose a replicated application as a service or route

SYNOPSISoc expose [OPTIONS]

DESCRIPTIONExpose containers internally as services or externally via routes There is also the ability to expose a deployment configuration, replication controller, service, or pod as a new service on a specified port. If no labels are specified, the new object will re−use the labels from the object it exposes.

OPTIONS−−allow−missing−template−keys=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. −−cluster−ip=""
ClusterIP to be assigned to the service. Leave empty to auto−allocate, or set to 'None' to create a headless service. −−dry−run=false
If true, only print the object that would be sent, without sending it. −−external−ip=""
Additional external IP address (not managed by Kubernetes) to accept for the service. If this IP is routed to a node, the service can be accessed by this IP in addition to its generated service IP. −f, −−filename=[]
Filename, directory, or URL to files identifying the resource to expose a service −−generator=""
The name of the API generator to use. Defaults to "route/v1". Available generators include "service/v1", "service/v2", and "route/v1". "service/v1" will automatically name the port "default", while "service/v2" will leave it unnamed. −−hostname=""
Set a hostname for the new route −l, −−labels=""
Labels to apply to the service created by this call. −−load−balancer−ip=""
IP to assign to the LoadBalancer. If empty, an ephemeral IP will be created and used (cloud−provider specific). −−name=""
The name for the newly created object. −o, −−output=""
Output format. One of: json|yaml|name|templatefile|template|go−template|go−template−file|jsonpath|jsonpath−file. −−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. −−path=""
Set a path for the new route −−port=""
The port that the resource should serve on. −−protocol=""
The network protocol for the service to be created. Default is 'TCP'. −−record=false
Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists. −R, −−recursive=false
Process the directory used in −f, −−filename recursively. Useful when you want to manage related manifests organized within the same directory. −−save−config=false
If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future. −−selector=""
A label selector to use for this service. Only equality−based selector requirements are supported. If empty (the default) infer the selector from the replication controller or replica set.) −−session−affinity=""
If non−empty, set the session affinity for the service to this; legal values: 'None', 'ClientIP' −−target−port=""
Name or number for the port on the container that the service should direct traffic to. Optional. −−template=""
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⟩]. −−type=""
Type for this service: ClusterIP, NodePort, LoadBalancer, or ExternalName. Default is 'ClusterIP'. −−wildcard−policy=""
Sets the WildcardPolicy for the hostname, the default is "None". Valid values are "None" and "Subdomain"

EXAMPLE # Create a route based on service nginx. The new route will re−use nginx's labels oc expose service nginx # Create a route and specify your own label and route name oc expose service nginx −l name=myroute −−name=fromdowntown # Create a route and specify a hostname oc expose service nginx −−hostname=www.example.com # Create a route with wildcard oc expose service nginx −−hostname=x.example.com −−wildcard−policy=Subdomain This would be equivalent to *.example.com. NOTE: only hosts are matched by the wildcard, subdomains would not be included. # Expose a deployment configuration as a service and use the specified port oc expose dc ruby−hello−world −−port=8080 # Expose a service as a route in the specified path oc expose service nginx −−path=/nginx # Expose a service using different generators oc expose service nginx −−name=exposed−svc −−port=12201 −−protocol="TCP" −−generator="service/v2" oc expose service nginx −−name=my−route −−port=12201 −−generator="route/v1" Exposing a service using the "route/v1" generator (default) will create a new exposed route with the "−−name" provided (or the name of the service otherwise). You may not specify a "−−protocol" or "−−target−port" option when using this generator.
