NAME¶
oc expose - Expose a replicated application as a service or route
SYNOPSIS¶
oc expose [OPTIONS]
DESCRIPTION¶
Expose containers internally as services or externally via routes.
There is also the ability to expose a deployment config, replication controller, service, or pod as a new service on a specified port. If no labels are specified, the new object will reuse 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="none"
Must be "none", "server", or "client". If
client strategy, only print the object that would be sent, without sending
it. If server strategy, submit server-side request without persisting the
resource.
--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.
--field-manager="kubectl-expose"
Name of the manager used to track field ownership.
-f, --filename=[]
Filename, directory, or URL to files identifying the resource to expose a
service
--hostname=""
Set a hostname for the new route
-k, --kustomize=""
Process the kustomization directory. This flag can't be used together with -f
or -R.
-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, go-template, go-template-file,
template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
--override-type="merge"
The method used to override the generated object: json, merge, or
strategic.
--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 service should serve on. Copied from the resource being
exposed, if unspecified
--protocol=""
The network protocol for the service to be created. Default is 'TCP'.
-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'
--show-managed-fields=false
If true, keep the managedFields when printing objects in JSON or YAML
format.
--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"
OPTIONS INHERITED FROM PARENT COMMANDS¶
--as=""
Username to impersonate for the operation. User could be a regular user or a
service account in a namespace.
--as-group=[]
Group to impersonate for the operation, this flag can be repeated to specify
multiple groups.
--as-uid=""
UID to impersonate for the operation.
--cache-dir="/home/abuild/.kube/cache"
Default cache directory
--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
--disable-compression=false
If true, opt-out of response compression for all requests to the server
--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.
--match-server-version=false
Require server version to match client version
-n, --namespace=""
If present, the namespace scope for this CLI request
--profile="none"
Name of profile to capture. One of
(none|cpu|heap|goroutine|threadcreate|block|mutex)
--profile-output="profile.pprof"
Name of the file to write the profile to
--request-timeout="0"
The length of time to wait before giving up on a single server request.
Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h).
A value of zero means don't timeout requests.
-s, --server=""
The address and port of the Kubernetes API server
--tls-server-name=""
Server name to use for server certificate validation. If it is not provided,
the hostname used to contact the server is used
--token=""

--user=""
The name of the kubeconfig user to use
--warnings-as-errors=false
Treat warnings received from the server as errors and exit with a non-zero
exit code
EXAMPLE¶
# Create a route based on service nginx. The new route will reuse 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 host name
oc expose service nginx --hostname=www.example.com
# Create a route with a 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
