.. code:: python
import ovh
# Instantiate. Visit https://api.ovh.com/createToken/?GET=/me
# to get your credentials
client = ovh.Client(
endpoint='ovh-eu',
application_key='<application key>',
application_secret='<application secret>',
consumer_key='<consumer key>',
)
# Print nice welcome message
print("Welcome", client.get('/me')['firstname'])
The python wrapper works with Python 3.7+.
The easiest way to get the latest stable release is to grab it from pypi <https://pypi.python.org/pypi/ovh>_ using pip.
.. code:: bash
pip install ovh
Alternatively, you may get latest development version directly from Git.
.. code:: bash
pip install -e git+https://github.com/ovh/python-ovh.git#egg=ovh
People looking for Python 2 compatibility should use 0.6.x version.
To interact with the APIs, the SDK needs to identify itself using an
application_key and an application_secret. To get them, you need
to register your application. Depending the API you plan to use, visit:
OVHcloud Europe <https://eu.api.ovh.com/createApp/>_OVHcloud US <https://api.us.ovhcloud.com/createApp/>_OVHcloud North-America <https://ca.api.ovh.com/createApp/>_So you Start Europe <https://eu.api.soyoustart.com/createApp/>_So you Start North America <https://ca.api.soyoustart.com/createApp/>_Kimsufi Europe <https://eu.api.kimsufi.com/createApp/>_Kimsufi North America <https://ca.api.kimsufi.com/createApp/>_Once created, you will obtain an application key (AK) and an application secret (AS).
The easiest and safest way to use your application's credentials is to create an
ovh.conf configuration file in application's working directory. Here is how
it looks like:
.. code:: ini
[default]
; general configuration: default endpoint
endpoint=ovh-eu
[ovh-eu]
; configuration specific to 'ovh-eu' endpoint
application_key=my_app_key
application_secret=my_application_secret
; uncomment following line when writing a script application
; with a single consumer key.
;consumer_key=my_consumer_key
; uncomment to enable oauth2 authentication
;client_id=my_client_id
;client_secret=my_client_secret
Depending on the API you want to use, you may set the endpoint to:
ovh-eu for OVHcloud Europe APIovh-us for OVHcloud US APIovh-ca for OVHcloud North-America APIsoyoustart-eu for So you Start Europe APIsoyoustart-ca for So you Start North America APIkimsufi-eu for Kimsufi Europe APIkimsufi-ca for Kimsufi North America APISee Configuration_ for more information on available configuration mechanisms.
.. note:: When using a versioning system, make sure to add ovh.conf to ignored
files. It contains confidential/security-sensitive information!
python-ovh supports two forms of authentication:
For OAuth2, first, you need to generate a pair of valid client_id and client_secret: you
can proceed by following this documentation
Once you have retrieved your client_id and client_secret, you can create and edit
a configuration file that will be used by python-ovh.
To allow your application to access a customer account using the API on your behalf, you need a consumer key (CK).
Here is a sample code you can use to allow your application to access a customer's information:
.. code:: python
import ovh
# create a client using configuration
client = ovh.Client()
# Request RO, /me API access
ck = client.new_consumer_key_request()
ck.add_rules(ovh.API_READ_ONLY, "/me")
# Request token
validation = ck.request()
print("Please visit %s to authenticate" % validation['validationUrl'])
input("and press Enter to continue...")
# Print nice welcome message
print("Welcome", client.get('/me')['firstname'])
print("Btw, your 'consumerKey' is '%s'" % validation['consumerKey'])
Returned consumerKey should then be kept to avoid re-authenticating your
end-user on each use.
.. note:: To request full and unlimited access to the API, you may use add_recursive_rules:
.. code:: python
# Allow all GET, POST, PUT, DELETE on /* (full API)
ck.add_recursive_rules(ovh.API_READ_WRITE, '/')
e-mail redirections may be freely configured on domains and DNS zones hosted by
OVHcloud to an arbitrary destination e-mail using API call
POST /email/domain/{domain}/redirection.
For this call, the api specifies that the source address shall be given under the
from keyword. Which is a problem as this is also a reserved Python keyword.
In this case, simply prefix it with a '_', the wrapper will automatically detect
it as being a prefixed reserved keyword and will substitute it. Such aliasing
is only supported with reserved keywords.
.. code:: python
import ovh
DOMAIN = "example.com"
SOURCE = "sales@example.com"
DESTINATION = "contact@example.com"
# create a client
client = ovh.Client()
# Create a new alias
client.post('/email/domain/%s/redirection' % DOMAIN,
_from=SOURCE,
to=DESTINATION,
localCopy=False
)
print("Installed new mail redirection from %s to %s" % (SOURCE, DESTINATION))
Let's say you want to integrate OVHcloud bills into your own billing system, you
could just script around the /me/bills endpoints and even get the details
of each bill lines using /me/bill/{billId}/details/{billDetailId}.
This example assumes an existing Configuration_ with valid application_key,
application_secret and consumer_key.
.. code:: python
import ovh
# create a client
client = ovh.Client()
# Grab bill list
bills = client.get('/me/bill')
for bill in bills:
details = client.get('/me/bill/%s' % bill)
print("%12s (%s): %10s --> %s" % (
bill,
details['date'],
details['priceWithTax']['text'],
details['pdfUrl'],
))
'Network burst' is a free service but is opt-in. What if you have, say, 10
servers in SBG-1 datacenter? You certainly don't want to activate it
manually for each servers. You could take advantage of a code like this.
This example assumes an existing Configuration_ with valid application_key,
application_secret and consumer_key.
.. code:: python
import ovh
# create a client
client = ovh.Client()
# get list of all server names
servers = client.get('/dedicated/server/')
# find all servers in SBG-1 datacenter
for server in servers:
details = client.get('/dedicated/server/%s' % server)
if details['datacenter'] == 'sbg1':
# enable burst on server
client.put('/dedicated/server/%s/burst' % server, status='active')
print("Enabled burst for %s server located in SBG-1" % server)
Thanks to the application key / consumer key mechanism, it is possible to finely track applications having access to your data and revoke this access. This examples lists validated applications. It could easily be adapted to manage revocation too.
This example assumes an existing Configuration_ with valid application_key,
application_secret and consumer_key.
.. code:: python
import ovh
from tabulate import tabulate
# create a client
client = ovh.Client()
credentials = client.get('/me/api/credential', status='validated')
# pretty print credentials status
table = []
for credential_id in credentials:
credential_method = '/me/api/credential/'+str(credential_id)
credential = client.get(credential_method)
application = client.get(credential_method+'/application')
table.append([
credential_id,
'[%s] %s' % (application['status'], application['name']),
application['description'],
credential['creation'],
credential['expiration'],
credential['lastUse'],
])
print(tabulate(table, headers=['ID', 'App Name', 'Description',
'Token Creation', 'Token Expiration', 'Token Last Use']))
Before running this example, make sure you have the
tabulate <https://pypi.python.org/pypi/tabulate>_ library installed. It's a
pretty cool library to pretty print tabular data in a clean and easy way.
pip install tabulate
Recent dedicated servers come with an IPMI interface. A lightweight control board embedded on the server. Using IPMI, it is possible to get a remote screen on a server. This is particularly useful to tweak the BIOS or troubleshoot boot issues.
Hopefully, this can easily be automated using a simple script. It assumes Java Web Start is fully installed on the machine and a consumer key allowed on the server exists.
.. code:: python
import ovh
import sys
import time
import tempfile
import subprocess
# check arguments
if len(sys.argv) != 3:
print("Usage: %s SERVER_NAME ALLOWED_IP_V4" % sys.argv[0])
sys.exit(1)
server_name = sys.argv[1]
allowed_ip = sys.argv[2]
# create a client
client = ovh.Client()
# create a KVM
client.post('/dedicated/server/'+server_name+'/features/ipmi/access', ipToAllow=allowed_ip, ttl=15, type="kvmipJnlp")
# open the KVM, when ready
while True:
try:
# use a named temfile and feed it to java web start
with tempfile.NamedTemporaryFile() as f:
f.write(client.get('/dedicated/server/'+server_name+'/features/ipmi/access?type=kvmipJnlp')['value'])
f.flush()
subprocess.call(["javaws", f.name])
break
except:
time.sleep(1)
Running is only a simple command line:
.. code:: bash
# Basic
python open_kvm.py ns1234567.ip-42-42-42.eu $(curl ifconfig.ovh)
# Use a specific consumer key
OVH_CONSUMER_KEY=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA python open_kvm.py ns1234567.ip-42-42-42.eu $(curl -s ifconfig.ovh)
You have 3 ways to provide configuration to the client:
The straightforward way to use OVHcloud's API keys is to embed them directly in the application code. While this is very convenient, it lacks of elegance and flexibility.
Example usage:
.. code:: python
client = ovh.Client(
endpoint='ovh-eu',
application_key='<application key>',
application_secret='<application secret>',
consumer_key='<consumer key>',
)
Alternatively it is suggested to use configuration files or environment variables so that the same code may run seamlessly in multiple environments. Production and development for instance.
This wrapper will first look for direct instantiation parameters then
OVH_ENDPOINT, OVH_APPLICATION_KEY, OVH_APPLICATION_SECRET and
OVH_CONSUMER_KEY environment variables. If either of these parameter is not
provided, it will look for a configuration file of the form:
.. code:: ini
[default]
; general configuration: default endpoint
endpoint=ovh-eu
[ovh-eu]
; configuration specific to 'ovh-eu' endpoint
application_key=my_app_key
application_secret=my_application_secret
consumer_key=my_consumer_key
The client will successively attempt to locate this configuration file in
./ovh.conf~/.ovh.conf/etc/ovh.confThis lookup mechanism makes it easy to overload credentials for a specific project or user.
Example usage:
.. code:: python
client = ovh.Client()
When using OVHcloud APIs (not So you Start or Kimsufi ones), you are given the opportunity to aim for two API versions. For the European API, for example:
Calling client.get, you can target the API version you want:
.. code:: python
client = ovh.Client(endpoint="ovh-eu")
# Call to https://eu.api.ovh.com/v1/xdsl/xdsl-yourservice
client.get("/v1/xdsl/xdsl-yourservice")
# Call to https://eu.api.ovh.com/v2/xdsl/xdsl-yourservice
client.get("/v2/xdsl/xdsl-yourservice")
# Legacy call to https://eu.api.ovh.com/1.0/xdsl/xdsl-yourservice
client.get("/xdsl/xdsl-yourservice")
You can also specify a custom configuration file. With this method, you won't be able to inherit values from environment.
Example usage:
.. code:: python
client = ovh.Client(config_file='/my/config.conf')
You can call all the methods of the API with the necessary arguments.
If an API needs an argument colliding with a Python reserved keyword, it
can be prefixed with an underscore. For example, from argument of
POST /email/domain/{domain}/redirection may be replaced by _from.
With characters invalid in python argument name like a dot, you can:
.. code:: python
import ovh
params = {}
params['date.from'] = '2014-01-01'
params['date.to'] = '2015-01-01'
# create a client
client = ovh.Client()
# pass parameters using **
client.post('/me/bills', **params)
If the user has not authenticated yet (ie, there is no valid Consumer Key), you
may force python-ovh to issue the call by passing _need_auth=True to
the high level get(), post(), put() and delete() helpers or
need_auth=True to the low level method Client.call() and
Client.raw_call().
This is needed when calling POST /auth/credential and GET /auth/time
which are used internally for authentication and can optionally be done for
most of the /order calls.
The high level get(), post(), put() and delete() helpers as well
as the lower level call() will returned a parsed json response or raise in
case of error.
In some rare scenario, advanced setups, you may need to perform customer
processing on the raw request response. It may be accessed via raw_call().
This is the lowest level call in python-ovh. See the source for more
information.
This wrapper uses standard Python tools, so you should feel at home with it.
Here is a quick outline of what it may look like. A good practice is to run
this from a virtualenv.
.. code:: bash
git clone https://github.com/ovh/python-ovh.git
cd python-ovh
python setup.py develop
