* feat: add CORS support for gRPC-Web on the frontend gRPC server A browser-based gRPC-Web client cannot read a cross-origin response. The request carries a non-simple content type, so the browser sends an `OPTIONS` preflight first, and it drops the call when the response has no `Access-Control-Allow-Origin`. Add `enable_cors` and `cors_allowed_origins` to `[grpc]`, threaded from `GrpcOptions` to `GrpcServerConfig` the same way `tls` is. The CORS layer sits outside `tonic_web::GrpcWebLayer`, so it answers the preflight before the request reaches the gRPC routes. It exposes `grpc-status`, `grpc-message` and `grpc-status-details-bin`, which a browser cannot read otherwise. An empty `cors_allowed_origins` allows any origin. `enable_cors` defaults to false, unlike `[http]`. `GrpcOptions` is shared by the public `[grpc]` section and the internal `[internal_grpc]` one, and serde cannot tell them apart, so a true default would also turn CORS on for the internal gRPC listeners: the frontend internal gRPC server, and the datanode and flownode gRPC servers. None of them authenticate callers, and a browser on the host or in the cluster network can reach all of them. Set `enable_cors = true` to turn it on. Tests start a real server on an ephemeral port and cover the preflight, a custom origin list, and the disabled case. Update the example TOMLs and regenerate config/config.md.

Pin both, the way the HTTP CORS test pins its own headers: a missing allow-headers header would let the preflight pass the origin check and still have the browser block every gRPC-Web call, which a non-browser client would never notice.

Setup tests for multiple storage backend
To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.
Take s3 for example. You need to set your S3 bucket, access key id and secret key:
# Settings for s3 test
GT_S3_BUCKET=S3 bucket
GT_S3_REGION=S3 region
GT_S3_ACCESS_KEY_ID=S3 access key id
GT_S3_ACCESS_KEY=S3 secret access key
Run
Execute the following command in the project root folder:
cargo test integration
Test s3 storage:
cargo test s3
Test oss storage:
cargo test oss
Test azblob storage:
cargo test azblob
Setup tests with Kafka wal
To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.
GT_KAFKA_ENDPOINTS = localhost:9092
Setup kafka standalone
cd tests-integration/fixtures
docker compose -f docker-compose.yml up kafka
Setup tests with etcd TLS
This guide explains how to set up and test TLS-enabled etcd connections in GreptimeDB integration tests.
Quick Start
TLS certificates are already at tests-integration/fixtures/etcd-tls-certs/.
-
Start TLS-enabled etcd:
cd tests-integration/fixtures docker compose up etcd-tls -d -
Start all services (including etcd-tls):
cd tests-integration/fixtures docker compose up -d --wait
Certificate Details
The checked-in certificates include:
ca.crt- Certificate Authority certificateserver.crt/server-key.pem- Server certificate for etcd-tls serviceclient.crt/client-key.pem- Client certificate for connecting to etcd-tls
The server certificate includes SANs for localhost, etcd-tls, 127.0.0.1, and ::1.
Regenerating Certificates (Optional)
If you need to regenerate the etcd certificates:
# Regenerate certificates (overwrites existing ones)
./scripts/generate-etcd-tls-certs.sh
# Or generate in custom location
./scripts/generate-etcd-tls-certs.sh /path/to/cert/directory
If you need to regenerate the mysql and postgres certificates:
# Regenerate certificates (overwrites existing ones)
./scripts/generate_certs.sh
# Or generate in custom location
./scripts/generate_certs.sh /path/to/cert/directory
Note: The checked-in certificates are for testing purposes only and should never be used in production.
