Easy and secure GitHub integration

In an effort to enhance the integration between GitHub and Octopus Deploy, two new features have been introduced, aiming to boost ease of use and security: OpenID Connect (OIDC) for GitHub Actions and the Octopus Deploy GitHub app. OIDC provides a streamlined authentication process between systems without the need for sharing long-lived credentials like API keys, which reduces the risk of unauthorized access and the burden of credential management. This change allows GitHub Actions to authenticate with Octopus Deploy through a secure OIDC identity, eliminating the need for storing sensitive API keys as secrets. Additionally, the Octopus Deploy GitHub app, currently under development and expected to be released in Q1 2024, will facilitate a seamless connection from Octopus Deploy to GitHub without requiring GitHub credentials, enabling Octopus to interact directly with GitHub-hosted repositories. This app will also pave the way for deeper integration, allowing Octopus to respond to GitHub events and access repository data such as commits and pull requests, thereby enhancing deployment efficiency and security.
