## Usage:
|
|
|
|
Creating resources:
|
|
|
|
```
|
|
from x import resource
|
|
|
|
node1 = resource.create('node1', 'x/resources/ro_node/', 'rs/', {'ip':'10.0.0.3', 'ssh_key' : '/vagrant/tmp/keys/ssh_private', 'ssh_user':'vagrant'})
|
|
|
|
node2 = resource.create('node2', 'x/resources/ro_node/', 'rs/', {'ip':'10.0.0.4', 'ssh_key' : '/vagrant/tmp/keys/ssh_private', 'ssh_user':'vagrant'})
|
|
|
|
keystone_db_data = resource.create('mariadb_keystone_data', 'x/resources/data_container/', 'rs/', {'image' : 'mariadb', 'export_volumes' : ['/var/lib/mysql'], 'ip': '', 'ssh_user': '', 'ssh_key': ''}, connections={'ip' : 'node2.ip', 'ssh_key':'node2.ssh_key', 'ssh_user':'node2.ssh_user'})
|
|
|
|
nova_db_data = resource.create('mariadb_nova_data', 'x/resources/data_container/', 'rs/', {'image' : 'mariadb', 'export_volumes' : ['/var/lib/mysql'], 'ip': '', 'ssh_user': '', 'ssh_key': ''}, connections={'ip' : 'node1.ip', 'ssh_key':'node1.ssh_key', 'ssh_user':'node1.ssh_user'})
|
|
```
|
|
|
|
to make connection after resource is created use `signal.connect`
|
|
|
|
To test notifications:
|
|
|
|
```
|
|
keystone_db_data.args # displays node2 IP
|
|
|
|
node2.update({'ip': '10.0.0.5'})
|
|
|
|
keystone_db_data.args # updated IP
|
|
```
|
|
|
|
If you close the Python shell you can load the resources like this:
|
|
|
|
```
|
|
from x import resource
|
|
|
|
node1 = resource.load('rs/node1')
|
|
|
|
node2 = resource.load('rs/node2')
|
|
|
|
keystone_db_data = resource.load('rs/mariadn_keystone_data')
|
|
|
|
nova_db_data = resource.load('rs/mariadb_nova_data')
|
|
```
|
|
|
|
Connections are loaded automatically.
|
|
|
|
|
|
You can also load all resources at once:
|
|
|
|
```
|
|
from x import resource
|
|
|
|
all_resources = resource.load_all('rs')
|
|
```
|
|
|
|
## CLI
|
|
|
|
You can do the above from the command-line client:
|
|
|
|
```
|
|
cd /vagrant
|
|
|
|
python cli.py resource create node1 x/resources/ro_node/ rs/ '{"ip":"10.0.0.3", "ssh_key" : "/vagrant/tmp/keys/ssh_private", "ssh_user":"vagrant"}'
|
|
|
|
python cli.py resource create node2 x/resources/ro_node/ rs/ '{"ip":"10.0.0.4", "ssh_key" : "/vagrant/tmp/keys/ssh_private", "ssh_user":"vagrant"}'
|
|
|
|
python cli.py resource create mariadb_keystone_data x/resources/data_container/ rs/ '{"image": "mariadb", "export_volumes" : ["/var/lib/mysql"], "ip": "", "ssh_user": "", "ssh_key": ""}'
|
|
|
|
python cli.py resource create mariadb_nova_data x/resources/data_container/ rs/ '{"image" : "mariadb", "export_volumes" : ["/var/lib/mysql"], "ip": "", "ssh_user": "", "ssh_key": ""}'
|
|
|
|
# View resources
|
|
python cli.py resource show rs/mariadb_keystone_data
|
|
|
|
# Connect resources
|
|
python cli.py connect rs/node2 rs/mariadb_keystone_data
|
|
|
|
python cli.py connect rs/node1 rs/mariadb_nova_data
|
|
|
|
# Test update
|
|
python cli.py update rs/node2 '{"ip": "1.1.1.1"}'
|
|
python cli.py resource show rs/mariadb_keystone_data # --> IP is 1.1.1.1
|
|
|
|
# View connections
|
|
python cli.py connections show
|
|

|
