Worked on the lfnovo/open-notebook repository to enhance deployment flexibility by introducing an environment-driven API host configuration, enabling IPv6 dual-stack support. Replaced the previously hardcoded API listen host in the process manager with a configurable API_HOST variable, allowing seamless adaptation across cloud and on-premises environments. Updated Docker configurations and documentation to reflect these changes, ensuring that the default behavior remains compatible while supporting overrides for specific deployment needs. Leveraged skills in Docker, configuration management, and infrastructure as code to lay the foundation for more reliable multi-environment deployments and smoother integration with automated deployment pipelines, focusing on network readiness and maintainability.
