- Updated docker-compose.yml to include PLAYWRIGHT_BROWSERS_PATH and MCP_PUBLIC_URL environment variables. - Modified k8s-manifests-complete.yaml to add Playwright and MCP configurations in the ConfigMap and deployment spec. - Adjusted resource limits in k8s manifests for improved performance during crawling. - Updated Dockerfiles to install Playwright browsers in accessible locations for appuser. - Added HTTP health check endpoint in mcp_server.py for better monitoring. - Enhanced MCP API to utilize MCP_PUBLIC_URL for generating client configuration. - Created MCP_PUBLIC_URL_GUIDE.md for detailed configuration instructions. - Documented changes and recommendations in K8S_COMPLETE_ADJUSTMENTS.md.

# Server Service - Kubernetes optimized build
|
|
# Optimizations:
|
|
# - Non-root user for security
|
|
# - Proper signal propagation for graceful shutdown
|
|
# - No HEALTHCHECK (K8s uses liveness/readiness probes)
|
|
# - Optimized layer caching
|
|
# - Minimal production footprint
