gRPC Hostname Example |
|
===================== |
|
|
|
The hostname example is a Hello World server whose response includes its |
|
hostname. It also supports health and reflection services. This makes it a good |
|
server to test infrastructure, like load balancing. |
|
|
|
The example requires grpc to already be built. You are strongly encouraged |
|
to check out a git release tag, since there will already be a build of gRPC |
|
available. |
|
|
|
### Run the example |
|
|
|
1. Navigate to this directory: |
|
|
|
```sh |
|
cd grpc/examples/python/xds |
|
``` |
|
|
|
2. Run the server |
|
|
|
```sh |
|
virtualenv venv -p python3 |
|
source venv/bin/activate |
|
pip install grpcio protobuf |
|
python server.py |
|
``` |
|
|
|
3. Verify the Server |
|
|
|
This step is not strictly necessary, but you can use it as a sanity check if |
|
you'd like. If you don't have it, install |
|
[`grpcurl`](https://github.com/fullstorydev/grpcurl/releases). This will allow |
|
you to manually test the service. |
|
|
|
Exercise your server's application-layer service: |
|
|
|
```sh |
|
> grpcurl --plaintext -d '{"name": "you"}' localhost:50051 |
|
{ |
|
"message": "Hello you from rbell.svl.corp.google.com!" |
|
} |
|
``` |
|
|
|
Make sure that all of your server's services are available via reflection: |
|
|
|
```sh |
|
> grpcurl --plaintext localhost:50051 list |
|
grpc.health.v1.Health |
|
grpc.reflection.v1alpha.ServerReflection |
|
helloworld.Greeter |
|
``` |
|
|
|
Make sure that your services are reporting healthy: |
|
|
|
```sh |
|
> grpcurl --plaintext -d '{"service": "helloworld.Greeter"}' localhost:50051 |
|
grpc.health.v1.Health/Check |
|
{ |
|
"status": "SERVING" |
|
} |
|
|
|
> grpcurl --plaintext -d '{"service": ""}' localhost:50051 |
|
grpc.health.v1.Health/Check |
|
{ |
|
"status": "SERVING" |
|
} |
|
```
