Knife vSphere ↑

DESCRIPTION: ↑

This is an Opscode Knife plugin to interact with VMware’s vSphere. This plugin currently supports the following:

Listings:

  • VMs

  • Folders

  • Templates

  • Datastores

  • VLANs (currently requires distributed vswitch)

  • Resource Pools and Clusters

  • Customization Specifications

  • Hosts in a Pool or Cluster

VM Operations:

  • Power on/off

  • Clone (with optional chef bootstrap and run list)

  • Delete

  • VMDK addition

  • Migrate

  • Connect/disconnect network

Clone-specific customization options (for linux guests):

  • Destination folder

  • CPU core count

  • Memory size

  • DNS settings

  • Hostname / Domain name

  • IP addresses / default gateway

  • vlan (currently requires distributed vswitch)

  • datastore

  • resource pool

INSTALLATION: ↑

gem install knife-vsphere

CONFIGURATION: ↑

For initial development, the plugin targets all communication at a vCenter instance rather than at specific hosts. Only named user authentication is currently supported; you can add the credentials to your knife.rb file:

knife[:vsphere_host] = "vcenter-hostname"
knife[:vsphere_user] = "privileged username"
knife[:vsphere_pass] = "your password"
knife[:vsphere_dc] = "your-datacenter"

If you get the following error, you may need to disable SSL certificate checking: ERROR: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

knife[:vsphere_insecure] = true

Credentials can also be specified on the command line for multiple VSphere servers/data centers

SUBCOMMANDS: ↑

This plugin provides the following Knife subcommands. Specific command options can be found by invoking the subcommand with a --help flag
