部署spring微服务后，Kubernetes中的负载均衡器没有连接到谷歌云平台中提到的端口。
是否有任何防火墙设置需要更改才能连接到已部署的服务？

这很可能是Kubernetes服务和/或部署的问题。GKE将自动提供映射到Service资源的端口所需的防火墙规则。
确保已在Service上公开port 80，并将其映射到Deployment的Pods上的有效端口
下面是一个使用Deployment和Service来暴露nginxpod的示例：
部署人员：
apiVersion: apps/v1 # API Version of this Object
kind: Deployment # This Object Type
metadata: # Allows you to specify custom metadata
name: nginx # Specifies the name of this object
spec: # The official specification matching object type schema
selector: # Label selector for pods
matchLabels: # Must match these label(s)
app: nginx # Custom label with value
template: # Template describes the pods that are created
metadata: # Standard objects metadata
labels: # Labels used to group/categorize objects
app: nginx # The name of this template
spec: # Specification of the desired behaviour of this pod
containers: # List of containers belonging to this pod (cannot be changed/updated)
- name: nginx # Name of this container
image: nginx # Docker image used for this container
ports: # Port mapping(s)
- containerPort: 80 # Number of port to expose on this pods ip
service.yaml：
apiVersion: v1
kind: Service
metadata:
name: nginx
labels:
app: nginx
spec:
type: LoadBalancer
selector:
app: nginx
ports:
- name: http
port: 80
targetPort: 80
要查看映射的ip地址(和端口(，可以运行：kubectl get services和kubectl describe pod <your pod name>`
如果您仍然有问题，请提供上面两个kubectl命令的输出。
祝你好运！
