snfinv is a a simplistic virtual machine provision and dynamic ansible inventory tool to be used on Synnefo IaaS deployments.
Install using `pip`:
$ pip install snfinvCreate an inventory.yml and define your nodes configuration:
provision:
networks:
priv1:
type: MAC_FILTERED
cidr: 10.12.21.0/24
coreos_node1:
project: xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx
flavour:
cpu: 2
ram: 1024
disk: 10
image: b9236d02-0904-4d00-8967-3279f0053d18 // CoreOS image
floating_ips: [auto, 83.212.221.53]
groups: ['sql']
keys: ['/home/user/.ssh/id_rsa.pub']
users: ['core']
networks:
priv1:
ip: 10.12.21.1
vars:
ansible_var1: 'value'
coreos_node2:
project: xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx
flavour:
cpu: 2
ram: 1024
disk: 10
image: b9236d02-0904-4d00-8967-3279f0053d18 // CoreOS image
floating_ips: [auto]
groups: ['web']
keys: ['/home/user/.ssh/id_rsa.pub']
users: ['core']
networks:
priv1:
ip: 10.12.21.1
vars:
ansible_var1: 'value'You can then provision the above specification by running within the directory the file above was created:
$ snfinv --provisionProvision script is reentrant and it won't try to recreate existing resources but it is not smart enough to delicately re-assemble flimsy configuration changes such as changes of vm flavor/ips/keys etc.
snfinv tool provides the required command line interface to be able to use is as a dynamic ansible inventory:
$ ansible `which snfinv` "coreos_node2" -m shell -a ls--dry
Used in conjuction with --provision. If set no calls will be sent to the synnefo api endpoints.
--list-hosts
Outputs /etc/hosts friendly list of the available nodes.
--config=<path-to-inventory.yml>
Provide a custom inventory.yml file. By default ./inventory.yml is used. SNFINV_CONFIG environment variable may also be used to declare the path to the provision configuration file.
--kamaki-config
Use a custom location for the kamaki config file.
