Developing cf CLI Plug-ins

Page last updated:

This topic describes creating and installing Cloud Foundry Command Line Interface (cf CLI) plug-ins.


You can create and install cf CLI plug-ins to provide custom commands. You can submit and share these plug-ins to the CF Community repository.


To use plug-ins, you must use cf CLI v7 or later. For information about downloading, installing, and uninstalling tcf CLI commands, see Installing the Cloud Foundry Command Line Interface.

Installing the Architecture

To prepare to create a plug-in:

  1. Implement the predefined plug-in interface from plugin.go in the Cloud Foundry CLI repository on GitHub.

  2. Clone the Cloud Foundry CLI repository from GitHub. To create a plug-in, you need the basic GO plugin.

Initializing the Plug-in

To initialize a plug-in:

  1. From within the main() method of your plug-in, call:


    The plugin.Start(...) function requires a new reference to the struct that implements the defined interface.

Invoking cf CLI Commands

To invoke cf CLI commands,

  1. From within the Run(...) method of your plug-in, call:


The Run(...) method receives the cliConnection as its first argument. The cliConnection.CliCommand([]args) returns the output printed by the command and an error.

The output is returned as a slice of strings. The error occurs if the call to the cf CLI command fails.

For more information, see Plugin API in the Cloud Foundry CLI repository on GitHub.

Installing a Plug-in

To install a plug-in:

  1. Run:

    cf install-plugin PATH-TO-PLUGIN-BINARY

    Where PATH-TO-PLUGIN-BINARY is the path to your plug-in binary.

For more information about developing plug-ins, see plugin_examples in the Cloud Foundry CLI repository on GitHub.
