This is the Dapr SDK for Python, based on the auto-generated proto client.

For more info on Dapr and gRPC, visit this link.

The repository generates following package

• dapr

pip install dapr-client

Note: Depending on your OS, you may want to use pip3 instead of pip.

A client can be created as follows:

from dapr.proto.dapr.v1 import dapr_pb2 as messages
from dapr.proto.dapr.v1 import dapr_pb2_grpc as services
import grpc
from google.protobuf.any_pb2 import Any

channel = grpc.insecure_channel('localhost:50001')
client = services.DaprStub(channel)

You can find a complete example here

You can execute this code using the local dapr runtime:

dapr run --protocol grpc --grpc-port=50001 python example.py

Note: Depending on your OS, you may want to use python3 instead of python.

Package can be generated as:

cd src
python setup.py sdist bdist_wheel

Note: Depending on your OS, you may want to use python3 instead of python.

The package will be generated in src/dist directory. For more information on generating packages, see python documentation at https://packaging.python.org/tutorials/packaging-projects/

As a good practice create a python virtual environment:

python3 -m venv <env_name>
source <env_name>/bin/activate

Run the following commands:

pip3 install -r grpc_requirements
sudo chmod +x protobuf.sh
. ./protobuf.sh

Run the following commands in powershell:

pip3 install -r grpc_requirements
.\protobuf.ps1

Add absolute path of src folder as PYTHONPATH environment variable.

Note: To use the newly generated proto buf stubs and gRPC interface replace daprd with edge version of daprd built from master branch. Refer this for instructions on how to build daprd from master.
