Nornir 访问 inventory

您可以使用以下inventory属性访问资源inventory：

from nornir import InitNornir
nr = InitNornir(config_file="config.yaml")


print(nr.inventory.hosts)
{'host1.cmh': Host: host1.cmh, 'host2.cmh': Host: host2.cmh, 'spine00.cmh': Host: spine00.cmh, 'spine01.cmh': Host: spine01.cmh, 'leaf00.cmh': Host: leaf00.cmh, 'leaf01.cmh': Host: leaf01.cmh, 'host1.bma': Host: host1.bma, 'host2.bma': Host: host2.bma, 'spine00.bma': Host: spine00.bma, 'spine01.bma': Host: spine01.bma, 'leaf00.bma': Host: leaf00.bma, 'leaf01.bma': Host: leaf01.bma}

inventory有两个类似字典的属性，hosts并且groups可以使用分别访问的host和组：

nr.inventory.hosts

{'host1.cmh': Host: host1.cmh,
 'host2.cmh': Host: host2.cmh,
 'spine00.cmh': Host: spine00.cmh,
 'spine01.cmh': Host: spine01.cmh,
 'leaf00.cmh': Host: leaf00.cmh,
 'leaf01.cmh': Host: leaf01.cmh,
 'host1.bma': Host: host1.bma,
 'host2.bma': Host: host2.bma,
 'spine00.bma': Host: spine00.bma,
 'spine01.bma': Host: spine01.bma,
 'leaf00.bma': Host: leaf00.bma,
 'leaf01.bma': Host: leaf01.bma}


nr.inventory.groups

{'global': Group: global,
 'eu': Group: eu,
 'bma': Group: bma,
 'cmh': Group: cmh}

nr.inventory.hosts["leaf01.bma"]
Host: leaf01.bma

host和组也是类似dict的对象：

host = nr.inventory.hosts["leaf01.bma"]
host.keys()

dict_keys(['site', 'role', 'type', 'asn', 'domain'])

host["site"]

'bma'
