Worked on enhancing Docker deployment documentation for the inovex/scrumlr.io repository, focusing on improving deployment reliability and security. The update clarified mandatory environment variables required for new deployments and provided detailed, step-by-step instructions for generating secure Postgres passwords and JWT private keys. Markdown was used to structure the documentation, ensuring clarity and accessibility. Additional troubleshooting guidance was added to help users resolve common issues, and the reverse proxy section was updated with concrete examples and relevant links. This work leveraged DevOps and self-hosting expertise to reduce deployment errors, streamline onboarding, and improve the maintainability of deployment documentation across the project.
