![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).

• 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

• 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

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}"
  username: "{VC_Username}"
  password: "{VC_Password}"
  datacenter_name: "Datacenter"           # VC datacenter name
  datastore_name: "vsphereDatastore"      # VC datastore name as above
  validate_cert: no                       # VC SSL Cert validation  

Please see configuration examples in the config directory.
