python開發F5相關功能

一、安裝依賴

pip install f5-sdk
pip install urllib3

二、相關代碼，參考https://f5-sdk.readthedocs.io/

1、創建、操作pool

from f5.bigip import ManagementRoot

# Connect to the BigIP
mgmt = ManagementRoot("bigip.example.com", "admin", "somepassword")

# Get a list of all pools on the BigIP and print their names and their
# members' names
pools = mgmt.tm.ltm.pools.get_collection()
for pool in pools:
    print pool.name
    for member in pool.members_s.get_collection():
         print member.name

# Create a new pool on the BIG-IP
mypool = mgmt.tm.ltm.pools.pool.create(name='mypool', partition='Common')

# Load an existing pool and update its description
pool_a = mgmt.tm.ltm.pools.pool.load(name='mypool', partition='Common')
pool_a.description = "New description"
pool_a.update()

# Delete a pool if it exists
if mgmt.tm.ltm.pools.pool.exists(name='mypool', partition='Common'):
    pool_b = mgmt.tm.ltm.pools.pool.load(name='mypool', partition='Common')
    pool_b.delete()

2、創建、操作member

members = pool_a.members_s
member = pool_a.members_s.members
# 創建
m1 = pool_a.members_s.members.create(partition='Common', name='192.168.101.50:80')
m2 = pool_a.members_s.members.create(partition='Common', name='192.168.101.51:80')

# load the pool members
m1 = pool_a.members_s.members.load(partition='Common', name='192.168.101.50:80')
m2 = pool_a.members_s.members.load(partition='Common', name='192.168.101.50:80')

# Get all of the pool members for pool_1 and print their names

for member in members:
    print member.name

# Delete our pool member m1
m1.delete()

3、創建、操作virtual server（VS）

 # 創建   
  try:
        mgmt = ManagementRoot("192.168.10.10", "admin", "admin")
        vs = mgmt.tm.ltm.virtuals.virtual.create(
            name='hn_vs3',
            partition='Common',
            destination='192.168.10.122:67',
            pool='mypool1',
            source='0.0.0.0/0'
        )
        print vs.raw
    except Exception as e:
        if isinstance(e, iControlUnexpectedHTTPError):
            text = json.loads(e.response.text)
            response['meaasge'] = text['message']
        else:
            response['meaasge'] = e


# 操作

response = {}
    try:
        mgmt = ManagementRoot("192.168.10.10", "admin", "admin")
        vs = mgmt.tm.ltm.virtuals.virtual.load(
            name='vs_test1',
            partition='Common'
        )
        if hasattr(vs, 'enabled'):
          # 禁用
            vs.disabled = True
        else:
          # 啟用
            vs.enabled = True
        vs.update()
    except Exception as e:
        print e
        if isinstance(e, iControlUnexpectedHTTPError):
            text = json.loads(e.response.text)
            response['meaasge'] = text['message']
        else:
            response['meaasge'] = e

注意事項：1、VS創建之后的狀態與pool的狀態有直接關系。

               2、pool創建之后的狀態與member和Health Monitors有關。

 

 

          3、錯誤處理，如果錯誤異常類型為icontrol.exceptions.iControlUnexpectedHTTPError時，需要特殊處理取得message信息。

 text = json.loads(e.response.text)
message = text['message']

        4、狀態為啟動時，屬性enabled為True，並沒有disabled屬性。為禁用時同理。

        5、想要打印出pool、member、vs的詳細信息，可以使用raw屬性。
