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

Backup completeness: JSON backup API now includes prompts and templates. Previously these were silently dropped during backup/restore, causing data loss on migration. 2. STDIO proxy for docker-image servers: servers with dockerImage but no packageName/command (like docmost) now use k8s Attach to connect to the container's PID 1 stdin/stdout instead of exec.

Resource Model & Design Decisions + +### ADR-001: Kubernetes-Style Resource Model + +| mcpctl Resource | K8s Analogy | Behavior | +|----------------|-------------|----------| +| **Server** | Deployment | Self-contained, complete definition. Contains image, command, transport, env refs, replicas. No external template dependencies at runtime. | +| **Instance** | Pod | Immutable, ephemeral, auto-managed by reconciliation loop. No `create instance` or `edit instance`. Delete triggers re-creation. | +| **Secret** | Secret | Holds sensitive key-value pairs. Servers reference via `env[].valueFrom.secretRef`. | +| **Project** | Namespace | Groups servers, configures ProxyModel and LLM provider. Generates `.mcp.json`. | +| **Prompt** | ConfigMap (sort of) | Instruction text delivered to Claude. Global or project-scoped. Priority-ranked. | +| **Template** | — | Blueprints for server creation. Used at create-time only, not runtime. | +| **RbacDefinition** | ClusterRoleBinding | Named policies with subjects and roleBindings. | + +### ADR-002: Profiles Replaced with Secrets + +The original `McpProfile` resource tried to be secrets, configmaps, and project-server links simultaneously. Environment variables declared in profiles were never actually passed to running containers. + +**Decision:** Replace with dedicated `Secret` resource following Kubernetes conventions: +```yaml +servers: + - name: ha-mcp + env: + - name: HOMEASSISTANT_TOKEN + valueFrom: + secretRef: + name: ha-credentials + key: HOMEASSISTANT_TOKEN +``` + +### ADR-003: Self-Contained Servers with Source Tracking + +Servers store complete definitions (no runtime template dependencies). Optional `source` metadata enables registry-based upgrades via 3-way diff (old snapshot vs current server vs new template). + +**Rationale:** Matches kubectl mental model. `get server X -o yaml > new.yaml && edit && apply` works naturally. Duplication is minimal (~10 lines YAML). + +### ADR-004: ConfigMaps Deferred + +Only Secrets implemented. ConfigMap separation can be added later if needed.
