The following is a sample of a gRPC client calling another container running gRPC server to execute a `SayHello` call.  The solution runs on Azure Container Apps.

## Deploy the sample

### Azure CLI

```bash

RESOURCE_GROUP="grpc-sample"

LOCATION="canadacentral"

LOG_ANALYTICS_WORKSPACE="aca-logs"

ACA_ENVIRONMENT="aca-env"

az extension add -y \

  --source https://workerappscliextension.blob.core.windows.net/azure-cli-extension/containerapp-0.2.0-py2.py3-none-any.whl

az provider register --namespace Microsoft.Web

az group create \

  --name $RESOURCE_GROUP \

  --location "$LOCATION"

az monitor log-analytics workspace create \

  --resource-group $RESOURCE_GROUP \

  --workspace-name $LOG_ANALYTICS_WORKSPACE

LOG_ANALYTICS_WORKSPACE_CLIENT_ID=`az monitor log-analytics workspace show --query customerId -g $RESOURCE_GROUP -n $LOG_ANALYTICS_WORKSPACE --out tsv`

LOG_ANALYTICS_WORKSPACE_CLIENT_SECRET=`az monitor log-analytics workspace get-shared-keys --query primarySharedKey -g $RESOURCE_GROUP -n $LOG_ANALYTICS_WORKSPACE --out tsv`

# Create the Container Apps Environment

az containerapp env create \

  --name $ACA_ENVIRONMENT \

  --resource-group $RESOURCE_GROUP \

  --logs-workspace-id $LOG_ANALYTICS_WORKSPACE_CLIENT_ID \

  --logs-workspace-key $LOG_ANALYTICS_WORKSPACE_CLIENT_SECRET \

  --location "$LOCATION"

# Create the gRPC backend internal service

az containerapp create \

  --name grpc-backend \

  --resource-group $RESOURCE_GROUP \

  --environment $ACA_ENVIRONMENT \

  --image ghcr.io/jeffhollan/grpc-sample-go/grpc-backend:main \

  --ingress 'internal' \

  --target-port 50051 \

  --transport 'http2'

GRPC_SERVER_ADDRESS=$(az containerapp show \

  --resource-group $RESOURCE_GROUP \

  --name grpc-backend \

  --query configuration.ingress.fqdn -otsv)

# Create the HTTPS frontend gRPC client container

az containerapp create \

  --name https-frontend \

  --resource-group $RESOURCE_GROUP \

  --environment $ACA_ENVIRONMENT \

  --image ghcr.io/jeffhollan/grpc-sample-go/https-frontend:main \

  --environment-variables GRPC_SERVER_ADDRESS=$GRPC_SERVER_ADDRESS':443' \

  --target-port 8050 \

  --ingress 'external' \

  --query configuration.ingress.fqdn

```

### Try the solution

After deploying, get the FQDN of the https-frontend and call it and hit the `/hello` endpoint. It will call the gRPC backend (via gRPC) and return a message to the client.

## Build and run the code

### Generate the protobuf client

`protoc protos/greet.proto -I. --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative`
