om3

The Go port and continuation of opensvc/opensvc.

om3 is a cluster orchestrator for small-to-mid clusters — a coherent alternative to stitching together systemd, container runtimes, and ad-hoc scripts, with symmetric orchestration on every node.

Features

• Targeted at 1-32 node clusters, human-readable service configurations and status
• Highly redundant cluster communications (unicast, multicast, disk, third-site relay)
• Deploy application stacks on containers, persistent or volatile volumes, or low-level resources — disks, volume groups, filesystems, IP addresses, app launchers
• Native, zeroconf, encrypted datastores, with keys exposed as files for your deployments
• Manage everything through the API, the om command line, or the ox terminal UI

Install

See the installation guide — the complete documentation lives there too.

Play

Deploy a simple service:

om test/svc/simple deploy --kw fs#1.type=flag --kw nodes='*' --kw orchestrate=ha

Then open an ox session and watch it move around the cluster.
