在 Kubernetes 中配置 Loki 时出现“不允许顶级‘配置’”错误我

Question

我正在尝试配置 Loki 以登录我的 Kubernetes 集群，但我不断收到以下错误消息：

Top level 'config' is not allowed. Most common configuration sections are exposed under the `loki` section. If you need to override the whole config, provide the configuration as a string that can contain template expressions under `loki.config`. Alternatively, you can provide the configuration as an external secret

这是我当前的 main.yaml 文件

我不确定我在这里做错了什么。谁能帮助我理解错误消息并修复此配置文件？

我尝试将

loki

放在

config

下方的

values:

上方，但它不会改变任何内容。

Answer 1

查看文档，这些设置似乎应该位于

loki.server

下，而不是

config.server

：

- name: "Deploy loki chart version {{loki_chart_version}} on cluster: {{cluster_name}}"
  kubernetes.core.helm:
    atomic: yes
    name: loki
    chart_ref: grafana/loki
    chart_version: "{{loki_chart_version}}"
    release_namespace: "{{loki_namespace}}"
    create_namespace: yes
    kubeconfig: "{{kube_config}}"
    update_repo_cache: no
    wait: yes
    wait_timeout: 5m
    force: no
    state: present
    values:
      # Mandatory label due to Kyverno policy
      podAnnotations:
        prometheus.io/scrape: "true"
        prometheus.io/port: "{{ loki_port | string }}"

      terminationGracePeriodSeconds: 300
      service:
        port: "{{ loki_port }}"

      loki:
        server:
          http_listen_port: "{{ loki_port }}"
        schema_config:
          configs:
            - from: 2021-09-01
              store: boltdb-shipper
              object_store: azure
              schema: v11
              index:
                prefix: index_
                period: 24h
        ...

看起来其他几个值也可能拼写错误（例如，有

loki.podAnnotations

和

gateway.podAnnotations

等，但我没有看到顶级

podAnnotations

）。
