部署到 GKE

• 访问 Google Cloud 控制台并创建你的 GKE 集群（这可能需要一些时间）。

• 获取集群凭据：

  gcloud container clusters get-credentials  --region us-central-1 --project 

• 上传清单文件：

  kubectl apply -f infra/production/k8s/app-config.yaml
  kubectl apply -f infra/production/k8s/secrets.yaml
  kubectl apply -f infra/production/k8s/api-gateway-deployment.yaml

• 检查部署的状态：

  kubectl get deployments
  kubectl get pods
