Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

Accessing Ceph object storage using the Swift API


Ceph supports RESTful API that is compatible with the basic data access model of the Swift API. In the last section, we covered accessing the Ceph cluster via the S3 API; in this section, we will learn to access it via the Swift API.

How to do it

To use Ceph object storage with the Swift API, we need the Swift subuser and secret keys that we created earlier in this chapter. This user information will then be passed using the Swift CLI tool in order to access Ceph object storage:

  1. On client-node1, a virtual machine installs the python Swift client:

    # apt-get install python-setuptools
    # easy_install pip
    # pip install --upgrade setuptools
    # pip install --upgrade python-swiftclient
    
  2. Get the swift subuser and secret keys:

    # radosgw-admin user info --uid mona
    
  3. Access Ceph object storage by listing the default bucket:

    # swift -A http://192.168.1.106:7480/auth/1.0 -U mona:swift -K 6vxGDhuEBsPSyX1E7vYvFrTXLVqoJByMHT+jnXPV list
    
  4. Add a new bucket, second-bucket...
