Create and manage containerized Slurm clusters for development, testing, and CI/CD workflows.
🚀 Getting Started 📖 Documentation
Inspired by kind (Kubernetes in Docker), sind offers a familiar CLI experience for quickly spinning up and tearing down Slurm clusters.
- Multi-node, multi-cluster & multi-realm — run controller, database, REST API, submitter, and worker nodes side by side, or spin up multiple clusters across isolated realms with shared networking
- System containers — full systemd-based nodes that emulate bare metal, compatible with Ansible, Chef, and other config management tools; unmanaged clusters leave Slurm itself to them
- Designed for CI/CD — runs on standard GitHub Actions runners with the runner's Docker daemon, no sudo or privileged containers; sind-action sets up clusters in a single step
- Multiple Slurm versions — official node images for the supported Slurm release lines (26.05 and 25.11) on linux/amd64 and linux/arm64, each with a full MPI stack, or bring your own image
- Job accounting, users and identity — a db node runs MariaDB and slurmdbd; users, groups and Slurm accounts with limits, and identity modes from local accounts to nss_slurm and auth/slurm
- REST API — slurmrestd on an api node with JWT authentication (Slurm 26.05)
- CVMFS — mount
/cvmfsread-only on every node, from the Docker host or a volume plugin - Worker lifecycle — dynamically add and remove worker nodes from running clusters
- Power cycle simulation — shutdown, reboot, freeze, and power-cycle nodes to simulate real-world failure scenarios
- Minimal dependencies — just Docker and a sind container image; usable as both a CLI tool and a Go library
- AI-ready via MCP — built-in MCP server lets AI assistants manage your Slurm clusters
This project is developed with the help of AI coding tools. Since September 2026, changes written by Anthropic's Claude Code agent are committed as Claude <noreply@anthropic.com> and/or carry a Co-Authored-By: Claude … trailer; earlier AI-assisted commits are not individually marked.
