## What Is Flamenco?
**Flamenco** is the premier open-source render farm management system for Blender, trusted by professional studios worldwide. Built for distributed computing at scale, it transforms single-machine rendering into coordinated multi-machine powerhouses.
**Community-Driven Excellence**: This isn't corporate software built to extract profit - it's community-grade engineering built with deep passion for the Blender ecosystem. Every optimization, every feature, every line of code is crafted with genuine care for artists and studios who depend on reliable, high-performance rendering infrastructure.
> **๐ Forked from**: [https://projects.blender.org/studio/flamenco](https://projects.blender.org/studio/flamenco) - This fork builds upon the excellent foundation created by Blender Studio, adding comprehensive Docker development environment optimizations and performance enhancements.

### ๐๏ธ Docker Volume Drivers for Production Storage
Flamenco's render farm requires shared storage accessible by all workers. Here's how to configure different Docker volume drivers for production deployments:
#### NFS (Network File System)
```yaml
# docker-compose.yml
volumes:
shared_storage:
driver: local
driver_opts:
type: nfs
o: addr=192.168.1.100,rw,nolock,hard,intr
device: ":/export/flamenco-shared"
services:
flamenco-manager:
volumes:
- shared_storage:/shared-storage
flamenco-worker:
volumes:
- shared_storage:/shared-storage
```
#### CIFS/SMB (Windows File Shares)
```yaml
# docker-compose.yml
volumes:
shared_storage:
driver: local
driver_opts:
type: cifs
o: username=flamenco,password=secure123,uid=1000,gid=1000,iocharset=utf8
device: "//192.168.1.100/flamenco-share"
services:
flamenco-manager:
volumes:
- shared_storage:/shared-storage
```
#### ZFS (High-Performance Storage)
```yaml
# docker-compose.yml
volumes:
shared_storage:
driver: local
driver_opts:
type: zfs
zfs-name: tank/flamenco-shared
services:
flamenco-manager:
volumes:
- shared_storage:/shared-storage
```
#### Block Storage (Cloud/SAN)
```yaml
# For AWS EFS, GCP Filestore, or SAN storage
volumes:
shared_storage:
driver: local
driver_opts:
type: nfs4
o: addr=fs-12345678.efs.us-west-2.amazonaws.com,rsize=1048576,wsize=1048576
device: ":/"
```
#### Third-Party Volume Plugins
```yaml
# NetApp, Pure Storage, etc.
volumes:
shared_storage:
driver: netapp:latest
driver_opts:
size: "500GB"
performance: "high"
snapshot_policy: "hourly"
```
#### Performance Considerations
- **NFS**: Best for mixed OS environments, excellent performance with NFSv4
- **CIFS/SMB**: Ideal for Windows-heavy environments, good Windows compatibility
- **ZFS**: Superior performance and data integrity, great for Linux environments
- **Block Storage**: Cloud-native scaling, excellent for multi-region deployments
- **Enterprise Storage**: Hardware-accelerated performance for high-throughput rendering
### ๐ Docker Swarm Multi-Node Deployment
