Worked on the Sybit-Education/Coding-Camp-2025 repository to overhaul the containerized deployment workflow, focusing on both reliability and security. Redesigned the Docker CI/CD pipeline using GitHub Actions, Dockerfile, and YAML, introducing automated image building, signing with cosign, and publishing via buildx. Addressed frontend deployment issues by ensuring proper docker pull invocation and correcting image pull syntax in the docker-compose configuration, which stabilized updates across environments. Integrated image signing and verification to prevent unsigned images from being deployed, reducing security risks. These changes streamlined release processes, minimized manual intervention, and improved consistency between staging and production infrastructure deployments.
