VMware vSphere® Flocker Driver

![vSphere Flocker Integration] (https://cloud.githubusercontent.com/assets/4852973/9564639/7e529746-4e62-11e5-9d61-3bc2ea4228fd.png)

ClusterHQ's Flocker provides an efficient and easy way to connect persistent storage with Docker containers. This project provides a plugin to provision persistent data volumes on VMware's vSphere storage datastores (VMFS, NFS, VSAN, VVOL).

Installation

Pre-requisites:

  • Setup a shared datastore on your VC.
  • Let the name of the datastore be say: vsphereDatastore
  • Create directory with name "FLOCKER" on this datastore. Flocker volumes will reside in this path. [vsphereDatastore] FLOCKER
  • VMware pyVmomi 6.0.0 (python 2.7.9+) or 5.5-2014.1.1 (python 2.7.6)

Install:

  • Deploy Ubuntu VMs (which you will use as Flocker nodes) on ESXi hosts with vsphereDatastore as the shared datastore.

    • Power off these VMs and enable disk uuid on these VMs by adding following to the vmx files.
    disk.EnableUUID​ = "TRUE"
    • Power on these VMs and install VMware Tools, scsitools and sg3-utils
      • Ubuntu
      sudo apt-get install -y open-vm-tools scsitools sg3-utils
    • One of these VMs should have Flocker control service installed.
      • Follow the Ubuntu specific steps on this guide for installing Flocker.

  • Steps to install vsphere-flocker-driver:

    /opt/flocker/bin/pip install git+https://github.com/vmware/vsphere-flocker-driver.git

Usage Instructions

To start the plugin on a node, a configuration file must exist on the node at /etc/flocker/agent.yml. This should be as follows:

version: 1
control-service:
  hostname: "{IP/Hostname of Flocker-Control Service}"
dataset:
  backend: "vsphere_flocker_plugin"
  vc_ip: "{VC_IP}"                        # VC IP address
  username: "{VC_Username}"               # VC privileged user
  password: "{VC_Password}"               # VC privileged user password
  datacenter_name: "Datacenter"           # VC datacenter name
  datastore_name: "vsphereDatastore"      # VC datastore name as above  
  ssl_verify_cert: no                     # VC SSL cert verification
  ssl_key_file: ""                        #    SSL keyfile path
  ssl_cert_file: ""                       #    SSL certfile path
  ssl_thumbprint: ""                      #    SSL host thumbprint

Please see configuration examples in the config directory.
