用于elasticsearch 7.0.1和kibana 7.0.1的docker-compose.yml [英] docker-compose.yml for elasticsearch 7.0.1 and kibana 7.0.1

问题描述

我在Windows 10上将Docker Desktop与linux容器一起使用，并希望在docker撰写文件上启动最新版本的elasticsearch和kibana容器。

I am using Docker Desktop with linux containers on Windows 10 and would like to launch the latest versions of the elasticsearch and kibana containers over a docker compose file.

一切在使用某些较旧的版本（如6.2.4）时可以正常工作。

Everything works fine when using some older version like 6.2.4.

这是6.2.4的有效docker-compose.yml文件。

This is the working docker-compose.yml file for 6.2.4.

version: '3.1'

services:

  elasticsearch:
   image: docker.elastic.co/elasticsearch/elasticsearch:6.2.4
   container_name: elasticsearch
   ports:
    - "9200:9200"
   volumes:
    - elasticsearch-data:/usr/share/elasticsearch/data
   networks:
    - docker-network

  kibana:
   image: docker.elastic.co/kibana/kibana:6.2.4
   container_name: kibana
   ports:
    - "5601:5601"
   depends_on:
    - elasticsearch
   networks:
    - docker-network

networks:
  docker-network:
    driver: bridge

volumes:
  elasticsearch-data:

我删除了所有已安装的Docker容器并通过将6.2.4更改为7.0.1修改了docker-compose.yml文件。
通过启动新的compose文件，一切看起来都很好，启动了elasticsearch和kibana容器。但是几秒钟后，elasticsearch容器退出了（kibana容器正在运行）。我重新启动了所有程序，将终端连接到了Elasticsearch容器，并看到以下错误消息：

I deleted all installed docker containers and adapted the docker-compose.yml file by changing 6.2.4 to 7.0.1. By starting the new compose file everything looks fine, both the elasticsearch and kibana containers are started. But after a couple of seconds the elasticsearch container exits (the kibana container is running further). I restarted everything, attached a terminal to the elasticsearch container and saw the following error message:

...
ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
...

要使Elasticsearch 7.0.1正常工作，必须在docker-compose.yml文件中进行哪些更改？

What must be changed in the docker-compose.yml file to get elasticsearch 7.0.1 working?

推荐答案

进行一些更改对我有用-

Making a few changes worked for me -

• 添加 cluster.initial_master_nodes 撰写Elasticsearch服务-

• Add cluster.initial_master_nodes to the elasticsearch service in compose -

environment:
  - cluster.initial_master_nodes=elasticsearch

vm.max_map_count 至少设置为262144-

vm.max_map_count on the linux box kernel setting needs to be set to at least 262144 -

$ sudo sysctl -w vm.max_map_count=262144

对于开发模式，您也可以使用以下设置-

For development mode, you can use below settings as well -

    environment:
      - discovery.type=single-node

为我工作的文件-

version: '2.2'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.0.1
    container_name: es01
    environment:
      - cluster.initial_master_nodes=es01
    ulimits:
      memlock:
        soft: -1
        hard: -1
    ports:
      - 9200

对于生产模式，您必须考虑按照官方文档中的建议使用多个ES节点/容器

For production mode, you must consider having multiple ES nodes/containers as suggested in the official documentation
