|

Create a disk for cloud-init to utilize nocloud
|
||||
|
||||
options:
|
||||
-h | --help show usage
|
||||
-d | --disk-format D disk format to output. default: raw
|
||||
can be anything supported by qemu-img or
|
||||
tar, tar-seed-local, tar-seed-net
|
||||
-H | --hostname H set hostname in metadata to H
|
||||
-f | --filesystem F filesystem format (vfat or iso), default: iso9660
|
||||
|
||||
-i | --interfaces F write network interfaces file into metadata
|
||||
-N | --network-config F write network config file to local datasource
|
||||
-m | --dsmode M add 'dsmode' ('local' or 'net') to the metadata
|
||||
default in cloud-init is 'net', meaning network is
|
||||
required.
|
||||
-V | --vendor-data F vendor-data file
|
||||
-v | --verbose increase verbosity
|
||||
|
||||
Note, --dsmode, --hostname, and --interfaces are incompatible
|
||||
with metadata.
|
||||
|
||||
Example:
|
||||
* cat my-user-data
|
||||
#cloud-config
|
||||
password: passw0rd
|
||||
chpasswd: { expire: False }
|

* echo "instance-id: \$(uuidgen || echo i-abcdefg)" > my-meta-data

* kvm -net nic -net user,hostfwd=tcp::2222-:22 \\
