NOTE: This project is the alpha stage of the golang port of https://github.com/opensvc/opensvc.
A cluster orchestrator with a distinctive feature set
- Simple and powerful
- Targeted at 1-32 nodes clusters
- Human readable services configurations and status
- Coherent alternative to a wide range of integration methods: from systemd to kubernetes
- Highly redundant cluster communications (ucast, mcast, disk, 3rd site relay)
- All nodes symmetric orchestration policies
- Orchestrate application stacks based on containers, and much more
- Provision stacks from template configurations, including disk, vg, fs, ip
- Optional CNI cluster networks, cluster DNS, ingress gateways
- DevOps, or pipelined delivery
