1. Log in to a cluster node and create a markdown template.

    vi <template-name>

    The content is as follows:

    apiVersion: v1
data:
  template: |
    {{- define "nm.default.markdown.test" }}
    {{- range .Alerts }}
    {{- $rawStatus := .Status }}
    {{- if eq $rawStatus "firing" }}
    ### <font color="yellow">{{ template "nm.default.message" . }}</font>
    {{- else }}
    ### <font color="green">{{ template "nm.default.message" . }}</font>
    {{- end }}
    {{- range .Labels.SortedPairs }}
    {{- if eq .Name "severity" }}
    {{- $color := "" }}
    {{- if eq .Value "critical" }}
    {{- $color = "red" }}
    {{- else if eq .Value "error" }}
    {{- $color = "orange" }}
    {{- else if eq .Value "warning" }}
    {{- $color = "yellow" }}
    {{- else if eq .Value "info" }}
    {{- $color = "blue" }}
    {{- end }}
    > <font color="{{$color}}">**{{ .Name | translate }}:  {{ .Value }}**</font>
    {{- else }}
    > **{{ .Name | translate }}**:  {{ .Value }}
    {{- end }}
    {{- end }}
    {{ range .Annotations.SortedPairs.Filter "runbook_url" "message" "summary" "summary_cn" }}
    > **{{ .Name | translate }}**:  {{ .Value }}
    {{- end }}
    {{ end }}
    {{- end }}

kind: ConfigMap
metadata:
  name: notification-manager-template-test
  namespace: kubesphere-monitoring-system

  2. Execute the following command to create a ConfigMap named notification-manager-template-test.

    kubectl apply -f <template-name>

  3. Configure WeCom in the Notification Channels or User Notification Settings to receive notification messages in WeCom sessions or WeCom group chats.

  4. View the wechat receiver.

    kubectl -n kubesphere-monitoring-system get receiver

    • Receivers starting with global-, such as global-wechat-receiver, are globally configured wechat receivers.

    • Receivers starting with a user name, such as admin-wechat-receiver, are tenant-level configured wechat receivers.

  5. Edit the corresponding wechat receiver to use the markdown template in notification messages.

    kubectl -n kubesphere-monitoring-system edit receiver <wechat-receiver-name>
    spec:
  wechat:
    enabled: true
    template: nm.default.markdown.test
    tmplText:
      name: notification-manager-template-test
      namespace: kubesphere-monitoring-system
    tmplType: markdown

    WeCom notification messages will be displayed using this markdown template.
