6 oc expose - Expose a replicated application as a service or route
7
11 oc expose [OPTIONS]
12
16 Expose containers internally as services or externally via routes
17 There is also the ability to expose a deployment configuration, repli‐
20 cation controller, service, or pod as a new service on a specified
21 port. If no labels are specified, the new object will re-use the labels
22 from the object it exposes.
23
27 --allow-missing-template-keys=true
28 If true, ignore any errors in templates when a field or map key is
29 missing in the template. Only applies to golang and jsonpath output
30 formats.
31 --cluster-ip=""
34 ClusterIP to be assigned to the service. Leave empty to auto-allo‐
35 cate, or set to 'None' to create a headless service.
36 --dry-run=false
39 If true, only print the object that would be sent, without sending
40 it.
41 --external-ip=""
44 Additional external IP address (not managed by Kubernetes) to ac‐
45 cept for the service. If this IP is routed to a node, the service can
46 be accessed by this IP in addition to its generated service IP.
47 -f, --filename=[]
50 Filename, directory, or URL to files identifying the resource to
51 expose a service
52 --generator=""
55 The name of the API generator to use. Defaults to "route/v1".
56 Available generators include "service/v1", "service/v2", and
57 "route/v1". "service/v1" will automatically name the port "default",
58 while "service/v2" will leave it unnamed.

62 Set a hostname for the new route
63 -l, --labels=""
66 Labels to apply to the service created by this call.

106 only if one already exists.
107 -R, --recursive=false

112 rectory.
113 --save-config=false
116 If true, the configuration of current object will be saved in its
117 annotation. Otherwise, the annotation will be unchanged. This flag is
118 useful when you want to perform kubectl apply on this object in the fu‐
119 ture.
120 --selector=""
123 A label selector to use for this service. Only equality-based se‐

404 # Create a route based on service nginx. The new route will re-use nginx's labels
405 oc expose service nginx
406 # Create a route and specify your own label and route name
408 oc expose service nginx -l name=myroute --name=fromdowntown
409 # Create a route and specify a hostname
411 oc expose service nginx --hostname=www.example.com
412 # Create a route with wildcard
414 oc expose service nginx --hostname=x.example.com --wildcard-policy=Subdomain
415 This would be equivalent to *.example.com. NOTE: only hosts are matched by the wildcard, subdomains would not be included.
416 # Expose a deployment configuration as a service and use the specified port
