Grafana 没有看到 loki（docker-compose 设置）

Question

我正在尝试使用相同的 docker compose 将我的应用程序登录到 grafana/loki/promtail 中，连接到 loki 时出现以下错误：

本地主机：3100 -> 404 页面未找到

当我尝试将其挂接到grafana时：

URL [http://loki:3100 ]-> Loki：错误网关。502错误的网关

我发现你必须在 grafana 中输入容器的名称才能检测到它，但我得到了同样的错误。

promtail 和 loki 容器在其日志中均未显示任何错误。

version: "3.7"

services:   
my-service-to-log:
    image: example:latest

    volumes:

    command: -config.file=/etc/loki/local-config.yaml

   promtail:

还有我的 promtail-config.yaml

   promtail:

      - /var/log:/var/log
    command: -config.file=/etc/promtail/config.yml

   grafana:
    image: grafana/grafana:latest
    ports:
      - "3000:3000"

我尝试从 grafana 容器到 loki 容器进行 nc 操作，似乎看到了它....有什么想法吗？

当您想从另一个容器访问 Loki 时，Loki 需要监听所有接口，而不仅仅是本地主机：

common:
  path_prefix: /tmp/loki
  storage:
    filesystem:
      chunks_directory: /tmp/loki/chunks
      rules_directory: /tmp/loki/rules
  replication_factor: 1
  ring:
    instance_addr: 0.0.0.0
    kvstore:
      store: inmemory
