Mothership CLI

Hypervisors

Mothership has built in support for launching a binary on multiple hypervisors. To do this it has dependencies on tools for each particular hypervisor.

Vcloud

Dependencies

  • Install ovftool (Requires a vmware account)
  • Install Docker (Used to add grub bootloader)

Environment variables

The following environment variables will have to be set in order for Vcloud to function.

ovfToolLocation:Location of the ovftool
vcloudUsername:Username for vcloud
vcloudPassword:Password for vcloud

Launch options

Mothership needs the following parameters set for launch

$ mothership launch --hypervisor vcloud
--vcloud-net Name of the network in vcloud to connect to
--vcloud-address Address to vcloud
--vcloud-org Name of vcloud organization
--vcloud-vapp Name of vapp to generate (overwrites existing vapps with same name)

Launch command

The final launch command will look like this:

$ mothership launch --hypervisor vcloud \
      --vcloud-net <name> \
      --vcloud-address <address> \
      --vcloud-org <name> \
      --vcloud-vapp <name> \
      <elf-binary-to-boot>

Multiple network interfaces

To have multiple network interfaces in your application create a vm.json in the same folder that launch is called from.

The following vm.json creates 3 interfaces:

{
  "net" : [
    {"device" : "vmxnet3", "mac" : "c0:01:0a:00:00:2a"},
    {"device" : "vmxnet3", "mac" : "c0:01:0a:00:00:2b"},
    {"device" : "vmxnet3", "mac" : "c0:01:0a:00:00:2c"}
  ]
}
