Worked on hardening the Grafana container runtime in the Accedian/grafana-docker repository, focusing on resolving permission and ownership issues across both OpenShift and non-OpenShift environments. Addressed deployment errors by ensuring runtime-generated files are group-writable and correctly owned by the Grafana user, and improved startup reliability by invoking the grafana-server executable with proper user permissions. Utilized shell scripting and containerization techniques to set appropriate umask values and manage file ownership transitions from root to the application user. These changes enhanced operational security, improved portability, and reduced permission-related failures, demonstrating a methodical approach to DevOps and scripting challenges in containerized deployments.
