        Overview
        ========
        
        This module provides a RESTful API client for Cloudvision\ |reg| Portal (CVP)
        which can be used for building applications that work with Arista CVP.
        
        When the class is instantiated the logging is configured. Either syslog,
        file logging, both, or none can be enabled. If neither syslog nor
        filename is specified then no logging will be performed.
        
        This class supports creating a connection to a CVP node and then issuing
        subsequent GET and POST requests to CVP. A GET or POST request will be
        automatically retried on the same node if the request receives a
        requests.exceptions.Timeout or ReadTimeout error. A GET or POST request
        will be automatically retried on the same node if the request receives a
        CvpSessionLogOutError. For this case a login will be performed before
        the request is retried. For either case, the maximum number of times a
        request will be retried on the same node is specified by the class
        attribute NUM\_RETRY\_REQUESTS.
        
        If more than one CVP node is specified when creating a connection, and a
        GET or POST request that receives a requests.exceptions.ConnectionError,
        requests.exceptions.HTTPError, or a requests.exceptions.TooManyRedirects
        will be retried on the next CVP node in the list. If a GET or POST
        request that receives a requests.exceptions.Timeout or
        CvpSessionLogOutError and the retries on the same node exceed
        NUM\_RETRY\_REQUESTS, then the request will be retried on the next node
        on the list.
        
        If any of the errors persists across all nodes then the GET or POST
        request will fail and the last error that occurred will be raised.
        
        The class provides connect, get, and post methods that allow the user to
        make RESTful API calls to CVP. See the example below using the get
        method.
        
        The class provides a wrapper function around the CVP RESTful API
        operations. Each API method takes the RESTful API parameters as method
        parameters to the operation method. The API class was added to the
        client class because the API functions are required when using the CVP
        RESTful API and placing them in this library avoids duplicating the
        calls in every application that uses this class. See the examples below
        using the API methods.

        Installation
        ============
        
        The source code for cvprac is provided on Github at
        https://github.com/aristanetworks/cvprac. All current development is
        done in the develop branch. Stable released versions are tagged in the
        master branch and uploaded to https://pypi.python.org.
        
        If your platform has internet access you can use the Python Package
        manager to install cvprac.
        
        ::
        
            admin:~ admin$ sudo pip install cvprac
        
        You can upgrade cvprac
        
        ::
        
            admin:~ admin$ sudo pip install --upgrade cvprac
        
        Development: Run from Source
        ----------------------------
        
        We recommend running cvprac in a virtual environment. For more
        information, read this:
        http://docs.python-guide.org/en/latest/dev/virtualenvs/
        
        These instructions will help you install and run cvprac from source.
        This is useful if you plan on contributing or if you would always like
        to see the latest code in the develop branch. Note that these steps
        require the pip and git commands.
        
        Step 1: Clone the cvprac Github repo
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        ::
        
            # Go to a directory where you'd like to keep the source
            admin:~ admin$ cd ~/projects
            admin:~ admin$ git clone https://github.com/aristanetworks/cvprac
            admin:~ admin$ cd cvprac
        
        Step 2: Check out the desired version or branch
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        ::
        
            # Go to a directory where you'd like to keep the source
            admin:~ admin$ cd ~/projects/cvprac
        
            # To see a list of available versions or branches
            admin:~ admin$ git tag
            admin:~ admin$ git branch
        
            # Checkout the desired version of code
            admin:~ admin$ git checkout v0.3.3
        
        Step 3: Install cvprac using Pip with -e switch
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        ::
        
            # Go to a directory where you'd like to keep the source
            admin:~ admin$ cd ~/projects/cvprac
        
            # Install
            admin:~ admin$ sudo pip install -e ~/projects/cvprac
        
        Step 4: Install cvprac development requirements
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        ::
        
            # Go to a directory where you'd like to keep the source
            admin:~ admin$ pip install -r dev-requirements.txt
        
        Getting Started
        ===============
        
        Once the package has been installed you can run the following example to
        verify that everything has been installed properly.
        
        Example
        -------
        
        Example using get method:
        
        ::
        
            >>> from cvprac.cvp_client import CvpClient
            >>> clnt = CvpClient()
            >>> clnt.connect(['cvp1', 'cvp2', 'cvp3'], 'cvp_user', 'cvp_word')
            >>> result = clnt.get('/cvpInfo/getCvpInfo.do')
            >>> print result
            {u'version': u'2016.1.0'}
            >>>
        
        Same example as above using the API method:
        
        ::
        
            >>> from cvprac.cvp_client import CvpClient
            >>> clnt = CvpClient()
            >>> clnt.connect(['cvp1', 'cvp2', 'cvp3'], 'cvp_user', 'cvp_word')
            >>> result = clnt.api.get_cvp_info()
            >>> print result
            {u'version': u'2016.1.0'}
            >>>
        
        Example using the API method to create a container, wait 5 seconds, then
        delete the container. Before running this example manually create a
        container named DC-1 on your CVP node.
        
        ::
        
            >>> import time
            >>> from cvprac.cvp_client import CvpClient
            >>> clnt = CvpClient()
            >>> clnt.connect(['cvp1'], 'cvp_user', 'cvp_word')
            >>> parent = clnt.api.search_topology('DC-1')
            >>> clnt.api.add_container('TORs', 'DC-1', parent['containerList'][0]['key'])
            >>> child = clnt.api.search_topology('TORs')
            >>> time.sleep(5)
            >>> result = clnt.api.delete_container('TORs', child['containerList'][0]['key'], 'DC-1', parent['containerList'][0]['key'])
            >>>
        
        Notes for API Class Usage
        =========================
        
        Containers
        ----------
        
        With the API the containers are added for all cases. If you add the
        container to the original root container ‘Tenant’ then you have to do a
        refresh from the GUI to see the container after it is added or deleted.
        If the root container has been renamed or the parent container is not
        the root container then an add or delete will update the GUI without
        requiring a manual refresh.
        
        Testing
        =======
        
        The cvprac module provides system tests. To run the system tests, you
        will need to update the ``cvp_nodes.yaml`` file found in test/fixtures.
        
        Requirements for running the system tests:
        
        -  Need one CVP node for test with a test user account. Create the same
           account on the switch used for testing. The user account information
           follows:
        
        ::
        
            username: CvpRacTest
            password: AristaInnovates
        
            If switch does not have correct username and/or password then the tests that
            execute tasks will fail with the following error:
        
            AssertionError: Execution for task id 220 failed
        
            and in the test log is the error:
        
            Failure response received from the netElement : ' Unauthorized User '
        
        -  Test has dedicated access to the CVP node.
        
        -  CVP node contains at least one device in a container.
        
        -  Container or device has at least one configlet applied.
        
        To run the system tests:
        
        -  run ``make tests`` from the root of the cvprac source folder.
