# kubectl expose

kubectl exposeSynopsisExpose a resource as a new Kubernetes service.Looks up a deployment, service, replica set, replication controller or pod by name and uses the selector for that resource as the selector for a new service on the specified port. A deployment or replica set will be exposed as a service only if its selector is convertible to a selector that service supports, i.e. when the selector contains only the matchLabels component. Note that if no port is specified via --port and the exposed resource has multiple ports, all will be re-used by the new service. Also if no labels are specified, the new service will re-use the labels from the resource it exposes.Possible resources include (case insensitive):pod (po), service (svc), replicationcontroller (rc), deployment (deploy), replicaset (rs)kubectl expose (-f FILENAME | TYPE NAME) [--port=port] [--protocol=TCP|UDP|SCTP] [--target-port=number-or-name] [--name=name] [--external-ip=external-ip-of-service] [--type=type] Examples # Create 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 # Create a service for a replication controller identified by type and name specified in "nginx-controller.yaml", which serves on port 80 and connects to the containers on port 8000 kubectl expose -f nginx-controller.yaml --port=80 --target-port=8000 # Create a service for a pod valid-pod, which serves on port 444 with the name "frontend" kubectl expose pod valid-pod --port=444 --name=frontend # Create 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 # Create a service for a replicated nginx using replica set, which serves on port 80 and connects to the containers on port 8000 kubectl expose rs nginx --port=80 --target-port=8000 # Create a service for an nginx deployment, which serves on port 80 and connects to the containers on port 8000 kubectl expose deployment nginx --port=80 --target-port=8000 Options--allow-missing-template-keys Default: trueIf 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 stringClusterIP to be assigned to the service. Leave empty to auto-allocate, or set to 'None' to create a headless service.--dry-run string[="unchanged"] Default: "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 stringAdditional 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 string Default: "kubectl-expose"Name of the manager used to track field ownership.-f, --filename stringsFilename, directory, or URL to files identifying the resource to expose a service-h, --helphelp for expose-k, --kustomize stringProcess the kustomization directory. This flag can't be used together with -f or -R.-l, --labels stringLabels to apply to the service created by this call.--load-balancer-ip stringIP to assign to the LoadBalancer. If empty, an ephemeral IP will be created and used (cloud-provider specific).--name stringThe name for the newly created object.-o, --output stringOutput format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).--override-type string Default: "merge"The method used to override the generated object: json, merge, or strategic.--overrides stringAn 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 stringThe port that the service should serve on. Copied from the resource being exposed, if unspecified--protocol stringThe network protocol for the service to be created. Default is 'TCP'.-R, --recursiveProcess the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.--save-configIf 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 stringA 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 stringIf non-empty, set the session affinity for the service to this; legal values: 'None', 'ClientIP'--show-managed-fieldsIf true, keep the managedFields when printing objects in JSON or YAML format.--target-port stringName or number for the port on the container that the service should direct traffic to. Optional.--template stringTemplate 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 stringType for this service: ClusterIP, NodePort, LoadBalancer, or ExternalName. Default is 'ClusterIP'.Parent Options Inherited--as stringUsername to impersonate for the operation. User could be a regular user or a service account in a namespace.--as-group stringsGroup to impersonate for the operation, this flag can be repeated to specify multiple groups.--as-uid stringUID to impersonate for the operation.--cache-dir string Default: "$HOME/.kube/cache"Default cache directory--certificate-authority stringPath to a cert file for the certificate authority--client-certificate stringPath to a client certificate file for TLS--client-key stringPath to a client key file for TLS--cluster stringThe name of the kubeconfig cluster to use--context stringThe name of the kubeconfig context to use--disable-compressionIf true, opt-out of response compression for all requests to the server--insecure-skip-tls-verifyIf true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure--kubeconfig stringPath to the kubeconfig file to use for CLI requests.--kuberc stringPath to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.--match-server-versionRequire server version to match client version-n, --namespace stringIf present, the namespace scope for this CLI request--password stringPassword for basic authentication to the API server--profile string Default: "none"Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)--profile-output string Default: "profile.pprof"Name of the file to write the profile to--request-timeout string Default: "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 stringThe address and port of the Kubernetes API server--storage-driver-buffer-duration duration Default: 1m0sWrites in the storage driver will be buffered for this duration, and committed to the non memory backends as a single transaction--storage-driver-db string Default: "cadvisor"database name--storage-driver-host string Default: "localhost:8086"database host:port--storage-driver-password string Default: "root"database password--storage-driver-secureuse secure connection with database--storage-driver-table string Default: "stats"table name--storage-driver-user string Default: "root"database username--tls-server-name stringServer name to use for server certificate validation.
