Port's Ocean is an open-source extensibility framework designed to connect third-party tools to a Port organization, streamlining platform engineering and unifying the software development lifecycle (SDLC). The framework provides a command-line interface (CLI) to scaffold custom integrations, which can be tailored to specific organizational needs using Python 3.11 or higher. Creating a successful integration requires careful planning and preparation, including assessing the need for a custom integration, securing admin permissions, understanding the tool being integrated, and gathering necessary API credentials. Ocean supports event-driven tasks, offering built-in defaults and flexibility for custom configurations, while ensuring that integration projects adhere to defined specifications and mapping configurations. Once developed, integrations can be tested using Ocean's CLI or makefile commands, with potential errors addressed before publishing. The final steps involve code cleanup, linter checks, and opening a pull request for review by the Ocean team, after which the integration becomes available in Port's data sources menu.
