允许在 kubernetes 集群外连接

Question

我的图表中有这个服务文件，如何允许 JDBC 在 kuberiq 外部连接，例如 DBeaver？我尝试配置 nodeport，但它一直失败。有人可以帮忙吗？

apiVersion: v1
    kind: Service
    metadata:
      name: {{ include "ignite.fullname" . }}
      labels:
        app: {{ include "ignite.fullname" . }}
    spec:
      ports:
        - name: jdbc
          port: 11211
          targetPort: 11211
        - name: spi-communication
          port: 47100
          targetPort: 47100
        - name: spi-discovery
          port: 47500
          targetPort: 47500
        - name: jmx
          port: 49112
          targetPort: 49112
        - name: sql
          port: 10800
          targetPort: 10800
        - name: rest
          port: 8080
          targetPort: 8080
        - name: thin-clients
          port: 10900
          targetPort: 10900
      clusterIP: None
      selector:

这是我想尝试连接的 ignite 服务，即使只是为了创建用户 $ kubectl describe svc ignite

我尝试像下面这样添加节点端口，但没有保存它。怎么了？

apiVersion: v1
kind: Service
metadata:
  name: {{ include "ignite.fullname" . }}
  labels:
    app: {{ include "ignite.fullname" . }}
spec:
  ClusterIP:
  ports:
    - name: jdbc
      port: 11211
      targetPort: 11211
    - name: spi-communication
      port: 47100
      targetPort: 47100
    - name: spi-discovery
      port: 47500
      targetPort: 47500
    - name: jmx
      port: 49112
      targetPort: 49112
    - name: sql
      port: 10800
      targetPort: 10800
      nodedport: 30008
    - name: rest
      port: 8080
      targetPort: 8080
    - name: thin-clients
      port: 10900
      targetPort: 10900
  selector:
    app: {{ include "ignite.fullname" . }}
  sessionAffinity: None
  type: NodePort

Answer 1

总结我们对评论的讨论：

解决方案是更改 headless service to Nodeport Service。

问题是编辑服务导致错误，因为某些服务的字段是不可变的（错误：Invalid value: "": field is immutable）。必须重新创建服务。

解决方案是在 helm 中使用 --force 标志。

> helm upgrade --help | grep force
--force        force resource updates through a replacement strategy
