rvc-knife - Chef knife module for RVC (Ruby vSphere Console)
This module integrates a subset of Chef's knife functionality with RVC. Nodes returned by knife search can be applied to VM operations and VMs can be queried for Chef node attributes.
RVC version 1.4.1 or higher - github.com/vmware/rvc
Chef version 0.9.12 or higher - www.opscode.com/chef
% gem install rvc % git clone https://github.com/dougm/rvc-knife.git % mkdir ~/.rvc % ln -s lib/rvc/modules/knife.rb ~/.rvc/
Chef knife configuration is expected to be in the appropriate place(s), such as ~/.chef/knife.rb
The 'knife.mark' command should be given the same QUERY parameter that would be given to 'knife search node QUERY'. The VirtualMachine(s) matching the chef node(s) of this query are saved as an RVC mark. The mark can be then be applied to any RVC commands using the '~mark_name' lookup syntax.
Note that the 'rvc mark' command only allows 'w+' as the name, any characters that do not match 'w' are replaced with an underscore '_'.
% rvc user:pass@vcenter-instance /vcenter-instance> knife.mark role:test-harness created mark 'role_test_harness' with 76 VMs /vcenter-instance> show ~role_test_harness /vcenter-instance/datacenter/vm/testvm-046: VirtualMachine /vcenter-instance/datacenter/vm/testvm-059: VirtualMachine /vcenter-instance/datacenter/vm/testvm-018: VirtualMachine /vcenter-instance/datacenter/vm/testvm-075: VirtualMachine ...
You can also use the 'name' option:
/vcenter-instance> knife.mark --name testvms role:test_harness created mark 'testvms' with 76 VMs
Example to power on all VMs in this role:
/vcenter-instance> vm.on ~testvms
Example to destroy all your Windows VMs:
/vcenter-instance> knife.mark os:windows created mark 'os_windows' with 18 VMs /vcenter-instance> vm.kill ~os_windows
The 'knife.show' command is just like 'knife node show' for given VM.
Example default, where 'em4j-eng050' is the VM name:
/vcenter-instance> cd datacenter/vm /vcenter-instance/datacenter/vm> knife.show em4j-eng050 Node Name: w1-em4j050.eng.vmware.com Environment: _default FQDN: w1-em4j050.eng.vmware.com IP: 10.136.28.75 Run List: role[em4j-harness] Roles: swaps-1x, em4j, em4j-harness, vcva-clovervm-vm, ... Recipes: hugetlb, vsphere::vminfo, hudson::node_ssh, swaps::linux, ... Platform: ubuntu 10.04
Example with attributes:
/vcenter-instance/datacenter/vm> knife.show em4j-eng050 -a hugetlb.vm hugetlb.vm: hugepages_treat_as_movable: 0 hugetlb_shm_group: 0 nr_hugepages: 548 nr_overcommit_hugepages: 0
