Replaces direct kubectl usage with SSH-based remote execution for Kubernetes deployment steps. Updates secrets and environment variables to use SSH key and connection info, and modifies manifest transfer and deployment verification to operate over SSH. This improves security and flexibility for remote Kubernetes server management.
Introduce Kubernetes manifests for backend, frontend, ingress, storage, and namespace setup under k8s/. Add Gitea Actions workflow for automated build and deployment to Kubernetes. Provide deployment and cluster setup guides in docs/ and project root. Update .gitignore to exclude Kubernetes secret files.
