plexd

plexd runs on every node in a Plexsphere-managed environment. It connects to the control plane, registers the node, establishes encrypted WireGuard mesh tunnels to peers, enforces network policies, and continuously reconciles local state against the desired state.

MVP / Work in Progress – This project is under active development. APIs, configuration formats, protocols, and internal interfaces are subject to change without prior notice. Do not rely on current behavior or interfaces for production use.

Key Capabilities

Self-Registration with one-time bootstrap tokens (Cloud-Init, K8s Secret, or manual enrollment)
Mesh Connectivity via direct encrypted WireGuard tunnels between authorized peers
NAT Traversal with STUN endpoint discovery and bridge-node relay fallback
Policy Enforcement through peer visibility filtering and local firewall rules
Configuration Reconciliation against the control plane's source of truth
Bridge Mode for user access, public ingress, site-to-site VPN, and NAT relay
Observability with metrics collection, log forwarding, and audit data forwarding
Remote Actions & Hooks with SHA-256 integrity verification
Local Node API exposing node state via Unix socket (bare-metal/VM) or CRD (Kubernetes)
Secure Access for platform-mediated SSH and Kubernetes API tunneling through the mesh

Runs on bare-metal servers, VMs, Kubernetes clusters, OpenWRT routers, and as bridge/gateway. Linux (amd64, arm64, mipsle).

Quick Start

# Install
curl -fsSL https://get.plexsphere.com/plexd | sh

# Enroll the node (interactive token prompt)
plexd join

# Run as a service
sudo plexd install
sudo systemctl enable --now plexd

See Installation & Quick Start for container, Kubernetes, OpenWRT, and bridge-mode deployments.
