A Python client for Doozer. This is partly based on Jeff Lindsay's and Neuman Vong's progrium/pydoozer. gevent has been taken out.
The latest is 0.1.5
.
Install via pip
:
$ pip install git+ssh://git@github.com/cloudControl/PyDoozerLib.git@0.1.5
There is a case when you try to install pydoozerlib
via python setup.py install
and run into following error:
[..]
Downloading http://protobuf.googlecode.com/files/protobuf-2.4.1.zip
Processing protobuf-2.4.1.zip
error: Couldn't find a setup script in /tmp/easy_install-riZxUs/protobuf-2.4.1.zip
Simply install protobuf
via pip
manually:
$ pip install protobuf
Then run python setup.py install
again!
Using the pip install git+ssh://...
method doesn't seem to run into this issue.
For more information check following issue: Protobuf Issue #66
Using PyDoozerLib
is dead simple.
Establish a connection to a running doozerd node:
from pydoozerlib import PyDoozerLib
client = PyDoozerLib(doozerd_host, doozerd_port)
client.connect()
Get the value at '/watch':
print client.get('/watch').value
Overwrite the given value at '/watch' with a new value:
client.set('/watch', 'Some random value to be set')
Delete a value:
rev = client.get('/watch').rev
client.delete('/watch', rev)
And disconnect:
client.disconnect()
Also refer to the examples/Example.py
file for a thorough example.
Make sure to go through following points if you want to modify PyDoozerLib
.
In the <project_root>/protobuf
directory you will find a msg.proto
file. First, install protobuf
, e.g. on Mac:
$ brew install protobuf
Then, compile the proto file with protoc
:
$ protoc --python_output=. msg.proto
This will create a msg_pb2.py
which can then be used in your Python project.
