SolidFire Plugin for ClusterHQ-Flocker

Plugin for SolidFire Flocker integration

Description

This plugin provides the ability to use SolidFire Storage Clusters as backend devices in a Flocker deployment.

Installation

Each of the following packages needs to be installed on EVERY Flocker Node

  • Open-iSCSI

    • Ubuntu
    sudo apt-get install open-iscsi
    • Redhat variants
    sud yum in stall iscsi-initiator-utils

  • SolidFire Flocker Plugin (NOTE: Be sure to use flockers installed pip)

    /opt/flockder/bin/pip install solidfire-flocker-driver
    • or
    git clone https://github.com/solidfire/solidfire-flocker-driver
cd solidfire-flocker-driver
sudo python ./setup.py install

Configuration

After install, this plugin reads configuration information on each Flocker node via the /etc/flocker/agent.yml config file. Note that you will want to use the same backend entries on each Flocker node. Below is an example configuration:

version: 1
control-service:
    hostname: "192.168.33.10"
dataset:
    backend: "solidfire_flocker_driver"
    endpoint: "https://admin:admin@192.168.160.3:443/json-rpc/7.0"
    profiles: "{'Gold':{'minIOPS': 10000, 'maxIOPS': 15000, 'burstIOPS': 20000},
                'Silver':{'minIOPS': 5000, 'maxIOPS': 10000, 'burstIOPS': 15000},
                'Bronze':{'minIOPS': 1000, 'maxIOPS': 5000, 'burstIOPS': 10000}}"

There are also additional optional values that can be specified in case of using VLAN's for your SVIP, or explicitly providing initiator names:

version: 1
control-service:
    hostname: "192.168.33.10"
dataset:
    backend: "solidfire_flocker_driver"
    endpoint: "https://admin:admin@192.168.160.3:443/json-rpc/7.0"
    profiles: "{'Gold':{'minIOPS': 10000, 'maxIOPS': 15000, 'burstIOPS': 20000},
                'Silver':{'minIOPS': 5000, 'maxIOPS': 10000, 'burstIOPS': 15000},
                'Bronze':{'minIOPS': 1000, 'maxIOPS': 5000, 'burstIOPS': 10000}}"
    initiator_name: "iqn.1993-08.org.debian:01:d7e03b6fc8fd"
    svip: "10.10.10.10"

Note the format of the endpoint is https://<login>:<password>@<mvip>/json-rpc/<element-version>

Profiles are used to set desired QoS of Volumes via Flockers Storage Profiles. Modify the IOP values as desired, however the key names are required.

Currenlty the SolidFire Flocker plugin utilizes Volume Access Groups for tenancy. It's required that you create a specific Voume Access Group on the SolidFire Cluster for Flocker, and assign the initiator IQN of each Flocker Node to the VAG prior to attempting to provision Volumes with Flocker. The vag_id setting show above would be the SolidFire ID of the Flocker VAG that you create.

After installing the plugin and setting up your configuration file you're now ready to restart the flocker agent service.
