Perfect! I've successfully created a comprehensive Polkadot Zombienet taskserv for the provisioning system. Here's what was built: 🧟 Polkadot Zombienet Taskserv (polkadot-zombienet) Created files: - taskservs/polkadot-zombienet/kcl/polkadot-zombienet.k - Complete KCL schema definitions - taskservs/polkadot-zombienet/default/provisioning.toml - Service metadata - taskservs/polkadot-zombienet/default/env-polkadot-zombienet.j2 - Environment configuration - taskservs/polkadot-zombienet/default/install-polkadot-zombienet.sh - Installation script - taskservs/polkadot-zombienet/default/prepare - Preparation and validation script - taskservs/polkadot-zombienet/default/network-config.toml.j2 - Dynamic network configuration template Network Templates: - simple-network.toml - Minimal 2-node relay chain (Alice + Bob) - parachain-network.toml - Relay chain with one parachain (3 validators + 1 collator) - multi-parachain-network.toml - Multi-parachain setup with XCM testing (4 validators + 3 parachains) Test Scripts: - test-basic.zndsl - Basic network functionality tests - test-parachain.zndsl - Parachain-specific functionality tests Service Management: - zombienet-service.sh.j2 - Service management script template 🔧 Key Features Multi-Provider Support - Native Provider: Downloads and runs Polkadot/Parachain binaries locally - Kubernetes Provider: Deploys networks to Kubernetes clusters with monitoring - Podman Provider: Uses Podman containers with rootless support Network Configuration - Relay Chain: Configurable validators (Alice, Bob, Charlie, Dave) - Parachains: Multiple parachain support with custom collators - Chain Types: Rococo-local, Westend-local, Kusama-local, Polkadot-local - Custom Images: Support for custom Docker images and binaries Management Tools - zombienet-manager: CLI tool for network management - spawn - Start networks - test - Run test suites - list - Show available networks - logs - View network logs - clean - Cleanup processes Testing Framework - ZNDSL Tests: Domain-specific language for network testing - Block Production: Verify relay chain and parachain block production - Connectivity: Test node peer connections - Registration: Verify parachain registration 📋 Usage Examples Deploy Simple Network ./core/nulib/provisioning taskserv create polkadot-zombienet # Start simple 2-node network zombienet-manager spawn # Start with custom network zombienet-manager spawn /var/lib/zombienet/networks/parachain-network.toml Test Networks # Run basic tests zombienet-manager test /var/lib/zombienet/test-basic.zndsl # Run parachain tests zombienet-manager test /var/lib/zombienet/test-parachain.zndsl Network Management # List available networks zombienet-manager list # View logs zombienet-manager logs # Cleanup zombienet-manager clean 🎯 Configuration Options Provider Settings - provider: native, kubernetes, podman - timeout: Network spawn timeout (default: 1000s) - enable_tracing: Enable detailed tracing - backchannel: Enable node communication backchannel Relay Chain - chain: rococo-local, westend-local, kusama-local, polkadot-local - default_image: Docker image for relay chain nodes - nodes: Array of validator nodes with custom configurations Parachains - id: Parachain ID (1-4000) - collators: Array of collator nodes - genesis_wasm: Custom parachain WASM runtime - balance: Initial parachain balance Provider-Specific - Kubernetes: namespace, monitoring, prometheus prefix - Podman: monitoring port, rootless support - Native: automatic binary downloads 🚀 Advanced Features Binary Management - Automatic download of Polkadot and Parachain binaries - Version-specific binary support - Custom binary path configuration - Symlink management for PATH access Monitoring & Logging - Centralized log management - Provider-specific monitoring (Prometheus, Grafana) - Network process tracking - Real-time log tailing Development Support - Pre-configured test networks - XCM testing setup - Multi-parachain environments - Custom collator configurations The service can be deployed using: ./core/nulib/provisioning taskserv create polkadot-zombienet This provides a complete ephemeral network testing platform for Polkadot/Substrate development, supporting everything from simple relay chains to complex multi-parachain networks with XCM testing capabilities. Perfect for developers working on parachain development, cross-chain messaging, and network validation testing.
