Prometheus Docker无法以`Template：(dynamic)：parse: template：:10: undefined "$labels"`启动

Question

我正试图在游牧民族上运行普罗米修斯。一切看起来都很好，但是当我在annotations中添加一个带有模板的警报规则时，它失败了。

下面是一个简单的警报规则：

groups:
- name: alertmanager.rules
  rules:
  - alert: AlertmanagerDown
    expr: up{job="alertmanager"} == 0
    for: 1s
    labels:
      severity: critical
    annotations:
      description: 'Alertmanager on {{ $labels.role }} instance {{ $labels.node }} has not produced any metrics for 5 minutes'
      summary: 'Alertmanager is down on {{ $labels.role }} instance {{ $labels.node }}'

容器失败，返回Template: (dynamic): parse: template: :10: undefined variable "$labels"

如果我删除annotations部分，它启动时没有任何问题。

我必须将left_delimiter和right_delimiter设置为{{和}} https://www.nomadproject.io/docs/job-specification/template.html#left_delimiter以外的值
