kubernetes - 如何在同一个命名空间中部署多个大使守护进程 - kubernetes

Question

我遇到了大使(特使)的问题。大使不同时支持 HTTP 和 HTTPS。因此，作为一种解决方法，我必须部署两组大使(一组用于 HTTP，另一组用于 HTTPS)。我已经部署了两组大使。

NAME                       READY   STATUS    RESTARTS   AGE
pod/ambassador-k7nlr       2/2     Running   0          55m
pod/ambassador-t2dbm       2/2     Running   0          55m
pod/ambassador-tls-7h6td   2/2     Running   0          107s

NAME                           TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
service/ambassador-admin       NodePort    10.233.58.170   <none>        8877:30857/TCP   18d
service/ambassador-admin-tls   NodePort    10.233.33.29    <none>        8878:32339/TCP   28m
service/ambassador-monitor     ClusterIP   None            <none>        9102/TCP         18d

NAME                            DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR                      AGE
daemonset.apps/ambassador       2         2         2       2            2           node-role.kubernetes.io/node=      58m
daemonset.apps/ambassador-tls   1         1         1       1            1           node-role.kubernetes.io/node=tls   107s

下面是我想用于 http 的两组 pod

pod/ambassador-k7nlr       2/2     Running   0          55m
pod/ambassador-t2dbm       2/2     Running   0          55m

而这个用于 https

pod/ambassador-tls-7h6td   2/2     Running   0          107s

下面是我的服务注释

getambassador.io/config: |
  ---
  apiVersion: ambassador/v0
  kind: Module
  name: tls
  config:
    server:
      secret: dashboard-certs
  ---
  apiVersion: ambassador/v0
  kind:  Mapping
  name:  dashboard_test_mapping
  host:  dashboard.example.com
  service: https://dashboard.test.svc.cluster.local
  prefix: /

这里apiVersion: ambassador/v0指的是两个大使集，所以我在服务注释中所做的任何更改都将反射(reflect)在这两个大使集中。

我想为特定的大使守护进程 (HTTPS) 设置此服务注释。

有什么建议 ？？

您可以使用 AMBASSADOR_ID为此，像这样:

getambassador.io/config: |
  ---
  ambassador_id: ambassador-1
  apiVersion: ambassador/v0
  kind: Module
  name: tls
  config:
    server:
      secret: dashboard-certs
  ---
  ambassador_id: ambassador-1
  apiVersion: ambassador/v0
  kind:  Mapping
  name:  dashboard_test_mapping
  host:  dashboard.example.com
  service: https://dashboard.test.svc.cluster.local
  prefix: /

然后在 DaemonSet 的 env 变量中指定这个 id:

env:
- name: AMBASSADOR_ID
  value: ambassador-1
