coreos-cloudinit is capable of reading userdata and metadata from the VMware
|
|
|
|
|
backdoor. This datasource can be enable with the `--from-vmware-backdoor` flag.
|
|
|
|
|
Userdata and metadata are passed from the hypervisor to the virtual machine
|
|
|
|
|
through guest variables. The following guest variables and their expected types
|
|
|
|
|
are supported by coreos-cloudinit:

Note: "n", "m", "l", and "x" are 0-indexed, incrementing integers. The

|
|
|
identifier for the interfaces does not correspond to anything outside of this
|
|
|
|
|
configuration; it is merely for mapping configuration values to each interface.
