What does it do and what's different?
-------------------------------------

Proxmoxer is a wrapper around the `Proxmox REST API v2 <https://pve.proxmox.com/pve-docs/api-viewer/index.html>`_.

It was inspired by slumber, but it dedicated only to Proxmox. It allows to use not only REST API over HTTPS, but
the same api over ssh and pvesh utility.

Like `Proxmoxia <https://github.com/baseblack/Proxmoxia>`_ it dynamically creates attributes which responds to the
attributes you've attempted to reach.

Installation
------------

.. code-block:: bash

    pip install proxmoxer

For 'https' backend install requests

.. code-block:: bash

    pip install requests

For 'ssh_paramiko' backend install paramiko

.. code-block:: bash

    pip install paramiko


Short usage information
-----------------------

The first thing to do is import the proxmoxer library and create ProxmoxAPI instance.

.. code-block:: python

    from proxmoxer import ProxmoxAPI
    proxmox = ProxmoxAPI('proxmox_host', user='admin@pam',
                         password='secret_word', verify_ssl=False)

This will connect by default through the 'https' backend.

It is possible to use already prepared public/private key authentication. It is possible to use ssh-agent also.

.. code-block:: python

    from proxmoxer import ProxmoxAPI
    proxmox = ProxmoxAPI('proxmox_host', user='proxmox_admin', backend='ssh_paramiko')

**Please note, https-backend needs 'requests' library, ssh_paramiko-backend needs 'paramiko' library,
openssh-backend needs 'openssh_wrapper' library installed.**

Queries are exposed via the access methods **get**, **post**, **put** and **delete**. For convenience added two
synonyms: **create** for **post**, and **set** for **put**.

.. code-block:: python

    for node in proxmox.nodes.get():
        for vm in proxmox.nodes(node['node']).openvz.get():
            print "{0}. {1} => {2}" .format(vm['vmid'], vm['name'], vm['status'])

    >>> 141. puppet-2.london.baseblack.com => running
        101. munki.london.baseblack.com => running
        102. redmine.london.baseblack.com => running
        140. dns-1.london.baseblack.com => running
        126. ns-3.london.baseblack.com => running
        113. rabbitmq.london.baseblack.com => running

same code can be rewritten in the next way:

.. code-block:: python

    for node in proxmox.get('nodes'):
        for vm in proxmox.get('nodes/%s/openvz' % node['node']):
            print "%s. %s => %s" %  (vm['vmid'], vm['name'], vm['status'])


for example next lines do the same job:

.. code-block:: python

    proxmox.nodes(node['node']).openvz.get()
    proxmox.nodes(node['node']).get('openvz')
    proxmox.get('nodes/%s/openvz' % node['node'])
    proxmox.get('nodes', node['node'], 'openvz')


Some more examples:

.. code-block:: python

    for vm in proxmox.cluster.resources.get(type='vm'):
        print("{0}. {1} => {2}" .format(vm['vmid'], vm['name'], vm['status']))


.. code-block:: python

    node = proxmox.nodes('proxmox_node')
    pprint(node.storage('local').content.get())

or the with same results

.. code-block:: python

    node = proxmox.nodes.proxmox_node()
    pprint(node.storage.local.content.get())


Example of creation of lxc container:

.. code-block:: python

    node = proxmox.nodes('proxmox_node')
    node.lxc.create(vmid=202,
        ostemplate='local:vztmpl/debian-9.0-standard_20170530_amd64.tar.gz',
        hostname='debian-stretch',
        storage='local',
        memory=512,
        swap=512,
        cores=1,
        password='secret',
        net0='name=eth0,bridge=vmbr0,ip=192.168.22.1/20,gw=192.168.16.1')

Example of creating the same lxc container with parameters in a dictonary.
This approach allows to add ``ssh-public-keys`` without getting syntax errors.

.. code-block:: python

    newcontainer = { 'vmid': 202,
        'ostemplate': 'local:vztmpl/debian-9.0-standard_20170530_amd64.tar.gz',
        'hostname': 'debian-stretch',
        'storage': 'local',
        'memory': 512,
        'swap': 512,
        'cores': 1,
        'password': 'secret',
        'net0': 'name=eth0,bridge=vmbr0,ip=192.168.22.1/20,gw=192.168.16.1' }
    node = proxmox.nodes('proxmox_node')
    node.lxc.create(**newcontainer)

Example of template upload:

.. code-block:: python

    local_storage = proxmox.nodes('proxmox_node').storage('local')
    local_storage.upload.create(content='vztmpl',
        filename=open(os.path.expanduser('~/templates/debian-6-my-core_1.0-1_i386.tar.gz'))))


Example of rrd download:

.. code-block:: python

    response = proxmox.nodes('proxmox').rrd.get(ds='cpu', timeframe='hour')
    with open('cpu.png', 'wb') as f:
        f.write(response['image'].encode('raw_unicode_escape'))

Example of usage of logging:

.. code-block:: python

    # now logging debug info will be written to stdout
    logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(levelname)s:%(name)s: %(message)s')
