Run three service

# service 01
./bin/gin-server -env-file .env.server01
# service 02
./bin/gin-server -env-file .env.server02
# service 03
./bin/chi-server -env-file .env.server03

Start client

run three client with Go

./bin/client -env-file .env.server01
./bin/client -env-file .env.server02
./bin/client -env-file .env.server03

Testing with other command

Use curl

run client with curl command

curl --header "Content-Type: application/json" \
    --data '{"name": "foobar"}' \
    http://localhost:8080/gitea.v1.GiteaService/Gitea

health check

curl --header "Content-Type: application/json" \
    --data '{"service": "gitea.v1.GiteaService"}' \
    http://localhost:8080/grpc.health.v1.Health/Check

Use grpcurl

run client with grpcurl command

grpcurl \
  -plaintext \
  -d '{"name": "foobar"}' \
  localhost:8080 \
  gitea.v1.GiteaService/Gitea

health check

grpcurl \
  -plaintext \
  -d '{"service": "gitea.v1.GiteaService"}' \
  localhost:8080 \
  grpc.health.v1.Health/Check
