Worked on the 1Panel-dev/appstore repository to deliver PostgreSQL 18 compatibility, focusing on deployment readiness and technical upgrades. Updated the Docker configuration to use PostgreSQL 18, ensuring the application could leverage the latest database features and security improvements. Introduced environment variables for database credentials and port settings, enhancing deployment flexibility and security across environments. Provided deployment-friendly documentation to support future migrations and reduce upgrade risks. The work primarily involved DevOps practices, leveraging Docker and PostgreSQL, and was implemented using YAML for configuration management. No bugs were fixed during this period, with efforts concentrated on feature delivery and infrastructure modernization.
