CLI

This is a command-line interface (CLI) for interacting with Service Catalog resources. svcat is a domain-specific tool to make interacting with the Service Catalog easier. While many of its commands have analogs to kubectl, our goal is to streamline and optimize the operator experience.

svcat communicates with Kubernetes cluster by directly using REST API - just like kubectl.

This document assumes that you’ve installed Service Catalog and the Service Catalog CLI onto your cluster. If you haven’t, please see the installation instructions.

Plugin Mode

To use svcat as a kubectl plugin, run the following command after downloading:

$ svcat install plugin
Plugin has been installed to ~/.kube/plugins/svcat. Run kubectl plugin svcat --help for help using the plugin.

When operating as a plugin, the commands are the same with the addition of the global kubectl configuration flags. One exception is that boolean flags aren’t supported when running in plugin mode, so instead of using --flag you must specify a value --flag=true.

Use

Run svcat --help to see the available commands.

Below are some common tasks made easy with svcat. The example output assumes that the User Provided Service Broker is installed on the cluster.

Register a broker

$ svcat register ups-broker --url http://ups-broker-ups-broker.ups-broker.svc.cluster.local --scope cluster
  Name:     ups-broker                                                  
  URL:      https://ups-broker-ups-broker.ups-broker.svc.cluster.local  
  Status:  

Find brokers installed on the cluster

This lists all brokers available in the current namespace and at the cluster scope.

$ svcat get brokers
     NAME      NAMESPACE                              URL                              STATUS  
+------------+-----------+-----------------------------------------------------------+--------+
  ups-broker               http://ups-broker-ups-broker.ups-broker.svc.cluster.local   Ready   

Trigger a sync of a broker’s catalog

$ svcat sync broker ups-broker
Synchronization requested for broker: ups-broker

List available service classes

This lists all classes available in the current namespace and at the cluster scope.

$ svcat get classes
                 NAME                  NAMESPACE     BROKER          DESCRIPTION

            "endIPAddress" : "75.70.113.131"
        },
        {

            "startIPAddress": "13.54.0.0",
            "endIPAddress" : "13.56.0.0"
        }

Remove all bindings from an instance

$ svcat unbind ups-instance
deleted ups-binding

Remove a single binding from an instance

$ svcat unbind  --name ups-binding
deleted ups-binding

Delete a service instance

Deprovisioning is the process of preparing an instance to be removed, and then deleting it. You must unbind delete all bindings before deprovisioning an instance.

$ svcat deprovision ups-instance
deleted ups-instance

Deregister a broker

Deregistering is the process of removing a broker and its associated classes and plans from the cluster. You must delete all active instances of its classes before deregistering a broker.

$ svcat deregister ups-broker --scope cluster
Successfully removed broker "ups-broker"

Namespaced Resource Support

svcat supports interaction with the namespaced versions of Service Catalog resources. The scope flag is used to indicate whether to execute the command in the cluster, namespace, or all scope.

Register a Namespaced Broker

svcat registers/deregisters brokers as namespaced brokers in the namespace of your current context by default. You can choose another namespace with the -n flag.

$ svcat register ups-broker --url http://ups-broker-ups-broker.ups-broker.svc.cluster.local -n foobar
  Name:     ups-broker                                                 
  URL:      http://ups-broker-ups-broker.ups-broker.svc.cluster.local  
  Status:

Provision an Instance of a Namespaced Class/Plan

svcat does not currently support provisioning instances of namespaced classes and plans.

Querying State

svcat commands that get information about the current state of the system also support the --scope flag, which is set to all by default. This will return all of the resources visible in the cluster scope, and the namespace of your current context. In the following examples, helmbroker is installed as a cluster broker, while ups-broker is installed in the default namespace.

$ svcat get brokers
     NAME      NAMESPACE                              URL                              STATUS
+------------+-----------+-----------------------------------------------------------+--------+
  helmbroker               http://helmbroker-helmbroker.helmbroker.svc.cluster.local   Ready
  ups-broker   default     http://ups-broker-ups-broker.ups-broker.svc.cluster.local   Ready
$ svcat get brokers -n foobar
       NAME      NAMESPACE                              URL                              STATUS
+------------+-----------+-----------------------------------------------------------+--------+
helmbroker               http://helmbroker-helmbroker.helmbroker.svc.cluster.local   Ready
$ svcat get brokers --scope namespace
     NAME      NAMESPACE                              URL                              STATUS
+------------+-----------+-----------------------------------------------------------+--------+
  ups-broker   default     http://ups-broker-ups-broker.ups-broker.svc.cluster.local   Ready
