Working with Plugins and Integrations in GoCD - Tutorial

Introduction

Plugins and integrations play a crucial role in extending the functionality of GoCD to meet your specific requirements. GoCD provides a rich ecosystem of plugins that enable you to integrate with external tools, customize your workflows, and enhance your continuous delivery process. In this tutorial, we will explore how to work with plugins and integrations in GoCD, including installing and configuring plugins, using built-in integrations, and creating custom plugins.

1. Installing and Configuring Plugins

Installing and configuring plugins in GoCD is a straightforward process. Follow these steps to install and configure a plugin:

1. Download the plugin binary or JAR file from the GoCD plugin repository or other trusted sources.
2. Copy the plugin file to the appropriate directory on the GoCD server.
3. Restart the GoCD server to load the newly installed plugin.
4. Configure the plugin by providing any required configuration parameters, such as API keys or connection settings.

Here's an example of installing and configuring the Slack Notification Plugin in GoCD:

2. Using Built-in Integrations

GoCD comes with several built-in integrations that provide seamless connectivity with popular tools and platforms. These integrations enable you to automate various stages of your delivery pipeline. Follow these steps to use a built-in integration:

1. Access the GoCD server administration dashboard.
2. Navigate to the "Admin" section and select the "Integrations" tab.
3. Enable the desired integration and provide any required configuration details, such as API keys or authentication credentials.
4. Save the configuration and test the integration by triggering a pipeline or performing a relevant action.

Here's an example of configuring the GitHub integration in GoCD:

3. Creating Custom Plugins

GoCD allows you to create custom plugins to extend its functionality beyond the built-in capabilities and available plugins. Follow these steps to create a custom plugin:

1. Choose a programming language and development framework to create your plugin.
2. Refer to the GoCD plugin development documentation to understand the plugin architecture and API.
3. Implement the desired functionality in your plugin code, such as a custom task plugin or a notification plugin.
4. Build and package your plugin according to the GoCD plugin specifications.
5. Install and configure your custom plugin using the steps mentioned earlier.

Common Mistakes

• Not verifying the compatibility of plugins with the GoCD version being used.
• Not following the plugin installation and configuration instructions provided by the plugin developers.
• Forgetting to restart the GoCD server after installing a new plugin.
• Overlooking the need for plugin dependencies or required libraries.
