Translate text with Amazon Translate and Google Translation.
- Translate text with Google Translation API and Amazon Translate API.
This API uses AWS IAM and GCP service account to use each translation API.
For instructions on how to create an AWS account, see Creating an IAM user in your AWS account .
For a GCP account, see Creating and managing service accounts.
Create a server key file and TLS certificate if an API uses TLS.
e.g., Self-signed certificate
$ cd manifest/api/secret
$ openssl genrsa -aes256 -passout pass:gsahdg -out server.pass.key 4096
$ openssl rsa -passin pass:gsahdg -in server.pass.key -out server.key
$ rm server.pass.key
$ openssl req -new -key server.key -out server.csr
...
$ openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

Need Several environment variables.
For details, see .env.example.
Several examples are here.
- Golang
- gRPC
- Kubernetes
- Golang: 1.14.4 darwin/amd64
- Docker: 20.10.2
- AWS IAM credentials, which can use Amazon Translate.
- Google service account, which can use Google Translation API.
We tested in the above environment.
- Install Golang by following Download and install.
- Run
go mod vendorto get modules.
Build
$ make build
go test
Run test with details: "-v" and "-cover"
$ make test
Format sources
Run "go fmt", "goimports", and "go lint".
$ make fmt
$ ./scripts/local.sh
Usage:
./scripts/local.sh Command
Example.
./scripts/local.sh build
Command:
run Run envoy and gRPC server on local.
run:go Run gRPC server on local.
run:envoy Run envoy on local.
down:envoy Stop envoy on local.
grpc Generate gRPC codes.- Directory structure refers to golang-standards/project-layout.
- API services a translation service with gRPC.
