From 5e45960a1847d3acfa5fc269e7d43cf5c41087f6 Mon Sep 17 00:00:00 2001 From: Michal Date: Wed, 8 Apr 2026 01:55:13 +0100 Subject: [PATCH] feat: add Kubernetes orchestrator for MCP server pod management mcpd can now deploy MCP server instances as Kubernetes pods instead of Docker containers. Set MCPD_ORCHESTRATOR=kubernetes to enable. - Add @kubernetes/client-node with thin wrapper (context enforcement via MCPD_K8S_CONTEXT to prevent multi-cluster mishaps) - Rewrite KubernetesOrchestrator: pod CRUD, pod IP extraction, exec via SPDY (one-shot + interactive), log streaming - Manifest generator: stdin:true for STDIO servers, args (not command) to preserve runner image entrypoint, security hardening - Orchestrator selection in main.ts via MCPD_ORCHESTRATOR env var - 25 unit tests for k8s orchestrator, all 624 tests pass Tested end-to-end on local k3s: - mcpd deployed via Pulumi, creates pods in mcpctl-servers namespace - NetworkPolicy verified: only mcpd can reach MCP server pods - Python runner (uvx) successfully runs aws-documentation-mcp-server
