Review Comment:
   The previous health check script explicitly validated the Nacos gRPC port (9848) in addition to the HTTP endpoint. The current health check only validates the HTTP endpoint. Since port 9849 has been added to the exposed ports and Nacos 2.x uses gRPC for service communication, consider adding a health check for the gRPC ports or using a compound health check command that validates both HTTP and gRPC endpoints to ensure complete service readiness.
   ```suggestion
         test: [ "CMD-SHELL", "curl -f http://localhost:8848/nacos/ && nc -z localhost 9848 && nc -z localhost 9849" ]
   ```

Review Comment:
   The advertise-client-urls has been changed from `http://127.0.0.1:2379` to `http://etcd:2379`. This is problematic because the advertise URL is what etcd tells clients to use for connecting. Since the etcd service is accessed from the host machine via port mapping (port 2379 is exposed), and the test clients connect using `127.0.0.1:2379` (as seen in registry/etcd/go-client/cmd/client.go and registry/etcd/go-server/cmd/server.go), changing the advertise URL to the Docker internal hostname `etcd` will break client connectivity. The advertise-client-urls should remain as `http://127.0.0.1:2379` or `http://0.0.0.0:2379` to work with external clients accessing via the port mapping.
   ```suggestion
         - --advertise-client-urls=http://127.0.0.1:2379
   ```

Review Comment:
   The initial-advertise-peer-urls and initial-cluster have been changed to use the Docker hostname `etcd` instead of `127.0.0.1`. While this change is generally acceptable for internal peer communication within the Docker network, it should be consistent with the advertise-client-urls change. Since the advertise-client-urls needs to be reverted to `127.0.0.1` or `0.0.0.0` for external client access, consider reverting these peer URLs as well for consistency, or ensure the etcd container can resolve the `etcd` hostname properly (which it should via Docker networking).
   ```suggestion
         - --advertise-client-urls=http://127.0.0.1:2379
         - --listen-peer-urls=http://0.0.0.0:2380
         - --initial-advertise-peer-urls=http://127.0.0.1:2380
         - --initial-cluster=etcd0=http://127.0.0.1:2380

Review Comment:
   The health check retry count has been reduced from 24 retries (120 seconds) to 3 retries (15 seconds) plus start_period. For Nacos, this gives a total of 45 seconds (30s start_period + 15s retries) compared to the original 120 seconds. If Nacos takes longer to start in certain environments (CI, resource-constrained systems), this may cause integration tests to fail prematurely. Consider increasing retries to at least 10 to allow more time for service initialization, especially in CI environments where resources may be limited.
   ```suggestion
         retries: 10
   ```

Review Comment:
   The health check retry count has been reduced from 24 retries (120 seconds) to 3 retries (15 seconds) plus start_period. For Polaris, this gives a total of 35 seconds (20s start_period + 15s retries) compared to the original 120 seconds. If Polaris takes longer to start in certain environments (CI, resource-constrained systems), this may cause integration tests to fail prematurely. Consider increasing retries to at least 10 to allow more time for service initialization.
   ```suggestion
         retries: 10
   ```

Review Comment:
   There appears to be trailing whitespace at the end of these lines. While this doesn't affect functionality, it's good practice to remove trailing whitespace for cleaner code.

Review Comment:
   The health check endpoint has changed from `/nacos/v1/console/health/liveness` to `/nacos/`. While `/nacos/` may work, the previous endpoint was specifically designed for health checks (liveness probe). Consider using the dedicated health check endpoint to ensure proper service readiness validation. The Nacos v2.x API typically provides `/nacos/v1/console/health/liveness` and `/nacos/v1/console/health/readiness` endpoints for this purpose.
   ```suggestion
         test: [ "CMD", "curl", "-f", "http://localhost:8848/nacos/v1/console/health/liveness" ]
   ```

Review Comment:
   确定 liveness check 可以吧 v1/console/health/liveness 去掉吗?
