如何连接运行在WSL2中的Grafana和Prometheus容器

Question

我在WSL2中将Prometheus和Grafana作为容器运行，我无法从Windows连接它们。我正在接收错误connect ECONNREFUSED 127.0.0.1:9090 (连接被拒绝)。

当我从WSL2内部访问它们时，一切都正常。

docker-compose.yaml

version: '3.5'

services:
  prometheus:

    image: prom/prometheus:latest
    container_name: prometheus
    volumes:
      - ./prometheus/:/etc/prometheus/
      - prometheus_data:/prometheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yaml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/etc/prometheus/console_libraries'
      - '--web.console.templates=/etc/prometheus/consoles'
    network_mode: "host"

  grafana:
    image: grafana/grafana:latest
    volumes:
      - grafana_data:/data
    network_mode: "host"

volumes:
  prometheus_data:
  grafana_data:

./prometheus/prometheus.yaml

看起来，当运行在WSL2中的服务器运行在:::地址上时会出现问题，比如Grafana - http.server address=[::]:3000的默认地址。

如果主机名更改为127.0.0.1，则一切正常。

将服务器IP地址从Grafana和Prometheus更改为127.0.0.1

在Prometheus上，有必要添加此命令--web.listen-address=127.0.0.1:9090。

在Grafana上，有必要添加这个环境变量GF_SERVER_HTTP_ADDR: "127.0.0.1"。

docker-compose.yaml，主机名设置为127.0.0.1

version: '3.5'

services:
  prometheus:

    image: prom/prometheus:latest
    container_name: prometheus
    volumes:
      - ./prometheus/:/etc/prometheus/
      - prometheus_data:/prometheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yaml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/etc/prometheus/console_libraries'
      - '--web.console.templates=/etc/prometheus/consoles'
      - '--web.listen-address=127.0.0.1:9090'
    network_mode: "host"

  grafana:
    image: grafana/grafana:latest
    volumes:
      - grafana_data:/data
    environment:
      GF_SERVER_HTTP_ADDR: "127.0.0.1"
    network_mode: "host"

volumes:
  prometheus_data:
  grafana_data:
