# Tugboat
Minimal version of `openkruise/kruise`. It was named Tugboat because it does minimal tasks with a small footprint compared to Kruise.
## Description
Introducing a lightweight Kubernetes operator for BroadcastJobs, enabling efficient pod deployment across your cluster.
### Key Features:
- **Effortless Node-Wide Deployments:** Seamlessly create BroadcastJobs to launch pods on all eligible nodes, streamlining cluster-wide operations.
- **Precise Node Selection:** Customize pod placement with node selectors for granular control.
- **Restart Management:** Define restart limits for individual pods to ensure resilience and manage potential failures.
- **Minimal Footprint:** Designed for efficiency with a smaller resource footprint than OpenKruise, ideal for resource-conscious environments.
- **Perfect for Learning Go:** Built as a learning project, it showcases Go development practices while creating a valuable Kubernetes tool.
Ideal for:
- Cluster-wide maintenance tasks
- Diagnostics and data collection
- Distributing workloads across all nodes
- Get started today and experience effortless cluster-wide pod deployments!
