NOTICE: This project is no longer under active development. F5 may still use internally for other project(s) but is no longer maintaining it publicly.
This project implements an SDK for the iControl® REST interface for BIG-IP®. Use this library to use python to automate a BIG-IP® via its REST API.
Please see the project documentation on Read the Docs: http://f5-sdk.readthedocs.io.
.. code:: shell
pip install f5-sdk
If you are using a pre-release version you must use the ``--pre`` option for the ``pip`` command.
.. code:: python
from f5.bigip import ManagementRoot # Connect to the BIG-IP mgmt = ManagementRoot("bigip.example.com", "admin", "somepassword") # Get a list of all pools on the BigIP and print their name and their # members' name 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 BigIP 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()
I intend the SDK to be easy to use and easy to hack. These overarching goals have a strong influence on my thinking when I am reviewing contributions, this means it is in their own interest that I make them as explicit as possible! The original interface specification was given to me by Shawn Wormke, who I believe was influenced by the Jira and Django projects. At the time I was reading Brett Slatkin's 'Effective Python', and I tried to follow its advice where possible. List of Patterns For Contributing Developers -------------------------------------------- #. Hack this list to make it more correct/complete For list additions assign @zancas as the PR reviewer. #. The call operator ``()`` means: "Try to communicate with the device." This is a strong contract we offer the consumer of the SDK. If an SDK function is invoked with the call operator ``()`` the program is initiating a communication with the device. That communication may fail before reaching the wire, but it has nonetheless been initiated. Conversely, if an SDK user evaluates an SDK expression that *DOES NOT* invoke the ``()`` call operator, then the SDK does *NOT* initiate a communication with the device. Any extension to the SDK that is not consistent with this contract is unlikely to be incorporated into the supported repository. #. The SDK is stupid The SDK doesn't decide things for the consumer, it's simply an interface so that Python programs can manipulate device resources without implementing custom URI/HTTP/network logic. Implications: #. NO DEFAULTS The consumers of this library are themselves Python programs. The Application programmer must say what they mean in their SDK-using program. It violates a critical separation of concerns to add default values to the SDK. Don't do it! (Unless you have a good reason.) #. Failures generate exceptions If the SDK enters a surprising or unexpected state it raises an exception. That's it. It's not generally up to the SDK to implement decision logic that handles edge-cases.. EXCEPT where the SDK is smoothing known issues in the device REST server. (See below.) #. The SDK never interprets responses It just records whatever response the device returns as attributes of the relevant object. (Except where handling significant inconsistencies in the device interface.) #. public-nonpublic pairs e.g. 'create' and '_create' XXX add content here. #. Handle known issues in the device REST server. The SDK intends to provide a rational interface to consumers that does the right thing. This means that one case where it does NOT simply do the stupid thing is when it handles a known idiosyncrasy in the device REST server. For example, some? resources ignore 'disable' and 'enable' configuration options when they are set to 'False'. Rather than force a consumer to learn about this quirk in the server, the SDK guesses that '"disable": False' means '"enable": True' , and submits that value on the consumers behalf. #. Implement-Reimplement-Abstract Solve the problem concretely and simply, if the same problem arises again, solve it concretely, then take the two concrete solutions and use them as your specification to generate an abstraction. In the SDK this usually goes something like this: #. Add logic to a concrete subclass #. Add similar logic to another concrete subclass #. Create a new method in a mixin or Abstract 'resource.py' base class and have both concrete subclasses inherit and use that method. Submodules ~~~~~~~~~~ bigip ^^^^^ Python API for configuring objects on a BIG-IP® device and gathering information from the device via the REST API. Filing Issues ------------- See the Issues section of `Contributing <CONTRIBUTING.md>`__. Contributing ------------ See `Contributing <CONTRIBUTING.md>`__ Test ---- Before you open a pull request, your code must have passing `pytest <http://pytest.org>`__ unit tests. In addition, you should include a set of functional tests written to use a real BIG-IP device for testing. Information on how to run our set of tests is included below. Unit Tests ~~~~~~~~~~ We use pytest for our unit tests. #. If you haven't already, install the required test packages listed in requirements.test.txt in your virtual environment. .. code:: shell $ pip install -r requirements.test.txt #. Run the tests and produce a coverage report. The ``--cov-report=html`` will create a ``htmlcov/`` directory that you can view in your browser to see the missing lines of code. .. code:: shell py.test --cov ./icontrol --cov-report=html open htmlcov/index.html Style Checks ~~~~~~~~~~~~ We use the hacking module for our style checks (installed as part of step 1 in the Unit Test section). .. code:: shell $ flake8 ./ Copyright --------- Copyright 2014-2016 F5 Networks Inc.
