ChubaoFS

Overview

ChubaoFS (储宝文件系统 in Chinese) is a distributed file system and object storage service for cloud native applications. It is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox project.

ChubaoFS has been commonly used as the underlying storage infrastructure for online applications, database or data processing services and machine learning jobs orchestrated by Kubernetes. An advantage of doing so is to separate storage from compute - one can scale up or down based on the workload and independent of the other, providing total flexibility in matching resources to the actual storage and compute capacity required at any given time.

Some key features of ChubaoFS include:

• Scale-out metadata management

• Strong replication consistency

• Specific performance optimizations for large/small files and sequential/random writes

• Multi-tenancy

• POSIX-compatible and mountable

• S3-compatible object storage interface

We are committed to making ChubaoFS better and more mature. Please stay tuned.

Build

$ git clone http://github.com/chubaofs/chubaofs.git
$ cd chubaofs
$ make

If the build succeeds, cfs-server and cfs-client can be found in build/bin

Docker

A helper tool called run_docker.sh (under the docker directory) has been provided to run ChubaoFS with docker-compose.

$ docker/run_docker.sh -r -d /data/disk

Note that /data/disk can be any directory but please make sure it has at least 10G available space.

To check the mount status, use the mount command in the client docker shell:

$ mount | grep chubaofs

To view grafana monitor metrics, open http://127.0.0.1:3000 in browser and login with admin/123456.

To run server and client separately, use the following commands:

$ docker/run_docker.sh -b
$ docker/run_docker.sh -s -d /data/disk
$ docker/run_docker.sh -c
$ docker/run_docker.sh -m

For more usage:

$ docker/run_docker.sh -h
