docker-compose: zipkin 无法连接到 elasticsearch

Question

我尝试使用 docker-compose.yml 设置 zipkin、elasticsearch、prometheus 和 grafana 当我运行 dockers时，在日志中看到：

dependencies_zipkin | 19/09/30 14:37:09 ERROR NetworkClient: Node [172.28.0.2:9200] failed (java.net.ConnectException: Connection refused (Connection refused)); no other nodes left - aborting...

我在 MacOS X 上 docker 2.1.0.3

我的docker-compose.yml的内容是这个：

version: '3.7'
services:
  storage:
    image: openzipkin/zipkin-elasticsearch7
    container_name: elasticsearch
    ports:
      - "9200:9200"
    environment:
      - "xpack.security.enabled=false"
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    restart: unless-stopped
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    volumes:
      - $PWD/prometheus:/etc/prometheus/
      - /tmp/prometheus:/prometheus/data:rw
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/usr/share/prometheus/console_libraries'
      - '--web.console.templates=/usr/share/prometheus/consoles'
    ports:
      - "9090:9090"
    restart: unless-stopped
  zipkin:
    image: openzipkin/zipkin
    container_name: zipkin
    depends_on: 
      - dependencies
      - storage
    environment: 
      - "STORAGE_TYPE=elasticsearch"
      - "ES_HOSTS=storage"
    ports:
      - "9411:9411"
    restart: unless-stopped
  grafana:
    image: grafana/grafana
    container_name: grafana
    ports:
      - "3000:3000"
    restart: unless-stopped
  dependencies:
    image: openzipkin/zipkin-dependencies
    container_name: dependencies_zipkin
    depends_on: 
      - storage
    environment:
      - "STORAGE_TYPE=elasticsearch"
      - "ES_HOSTS=storage"

当我连接到 localhost:9200 时，我看到 elasticsearch 工作正常并且在端口 9411 上部署了 zipkin 但我有错误：

ERROR: cannot load service names: server error (Service Unavailable)(due to the network error

在日志中，我有以下信息：

105 ^[[35mdependencies_zipkin |^[[0m 19/09/30 14:45:20 ERROR NetworkClient: Node [172.28.0.2:9200] failed (java.net.ConnectException: Connection refused (Connection refused)); no other nodes left - aborting...

还有这个

^[[31mzipkin |^[[0m java.lang.IllegalStateException: couldn't connect any of [Endpoint{storage:80, ipAddr=172.28.0.2, weight=1000}]

有什么想法吗？

更新通过使用 mysql 它工作正常，所以问题出在弹性搜索级别。我也尝试使用

"STORAGE_PORT_9200_TCP_ADDR=127.0.0.1"

但问题仍然存在。

更新由于提到了 Brian 给出的解决方案，我必须使用：

ES_HOSTS=http://storage:9300

关键在端口上，我用的是9200端口

zipkin 和 es 之间错误消失，但 es 和 zipkin-dependencies 之间仍然出现错误。

Answer 1

问题在于您的 ES_HOSTS 变量，来自文档 here:

ES_HOSTS: A comma separated list of elasticsearch base urls to connect to ex. http://host:9200. Defaults to "http://localhost:9200".

所以你需要：ES_HOSTS=http://storage:9200

Answer 2

我终于有了这个文件：

version: '3.7'

services:
  storage:
    image: openzipkin/zipkin-elasticsearch7
    container_name: elasticsearch
    ports:
      - 9200:9200

  zipkin:
    image: openzipkin/zipkin
    container_name: zipkin
    environment: 
      - STORAGE_TYPE=elasticsearch
      - "ES_HOSTS=elasticsearch:9300"
    ports:
      - 9411:9411
    depends_on: 
      - storage

  dependencies:
    image: openzipkin/zipkin-dependencies
    container_name: dependencies
    entrypoint: crond -f
  depends_on:
    - storage
  environment:
    - STORAGE_TYPE=elasticsearch
    - "ES_HOSTS=elasticsearch:9300"
    - "ES_NODES_WAN_ONLY=true"

prometheus:
  image: prom/prometheus:latest
  container_name: prometheus
  volumes:
    - $PWD/prometheus:/etc/prometheus/
    - /tmp/prometheus:/prometheus/data:rw
  command:
    - '--config.file=/etc/prometheus/prometheus.yml'
    - '--storage.tsdb.path=/prometheus'
    - '--web.console.libraries=/usr/share/prometheus/console_libraries'
    - '--web.console.templates=/usr/share/prometheus/consoles'
  ports:
    - "9090:9090"

grafana:
  image: grafana/grafana
  container_name: grafana
  depends_on:
    - prometheus
  ports:
    - "3000:3000"

主要区别在于

的用法

"ES_HOSTS=elasticsearch:9300"

而不是

"ES_HOSTS=storage:9300"

在依赖项配置中，我在依赖项中添加了入口点：

entrypoint: crond -f This one is really the key to not have the exception when I start docker-compose.

为了解决这个问题，我检查了这个项目：https://github.com/openzipkin/docker-zipkin

剩下的问题是：为什么我需要使用入口点：crond -f

docker-compose: zipkin 无法连接到 elasticsearch
