Example 2: Write & Publish gRPC Python Service

This example shows you how to write and publish a gRPC Python service

Please see:

Compile service API

cat echo_service.proto
python3 -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. ./echo_service.proto

Start service server

cat echo_service.py
screen -d -m python3 echo_service.py

Check that service works

cat echo_client.py
python3 echo_client.py

Publish service to the Registry

snet identity publisher
snet service metadata_init . EchoService $PUBLISHER_ADDR --encoding proto --service_type grpc
snet service metadata_set_fixed_price 3
snet service metadata_add_endpoints
cat service_metadata.json
snet service publish ExampleOrganization EchoService --yes

Start daemon

cat snetd.config.json
screen -d -m snetd-linux-amd64

Call service via SingularityNet

snet identity caller
snet client open_init_channel_registry ExampleOrganization EchoService 50 57600 -y
snet client call 0 3 localhost:8080 echo '{"message": "hello"}'

Stop the service
