Octopus Deploy's Release 3.11 introduces a comprehensive Certificates feature designed to streamline the management and automation of certificates within deployment pipelines, addressing the complexity and inefficiency often encountered in these processes. Users can now store certificates in PFX, PEM, or DER formats, and utilize them as typed variables within Octopus, which can be expanded upon deployment to simulate object-oriented properties. The update includes an Import Certificate deployment step, allowing for easy integration into Windows Certificate Stores and the configuration of HTTPS bindings. Additionally, certificates can be exported in the original or modified formats, with options for private-key inclusion, and expiry notifications can be configured to alert users when certificates are nearing expiration. The Replace feature enables seamless updating of certificates by inheriting properties from the expired version, and the functionality is accessible via Octopus's HTTP REST API and .NET client library, facilitating integration into existing X.509 certificate management processes. Paul Stovell, the founder of Octopus Deploy, emphasizes the importance of user feedback for further enhancements.
