Question

我有以下Docker-compose 3文件：

version: '3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4
    container_name: elasticsearch
    ...
    ...
    volumes:
      - /path/to/elasticsearch:/usr/share/elasticsearch/data
      - /path/to/elasticsearch/backup:/opt/elasticsearch/backup
    ports:
      - 9200:9200
    networks:
      - elasticnetwork

因此，我将path.repo设置为/ path / to / elasticsearch / backup。但是，运行curl http://127.0.0.1:9200/_nodes/?pretty不会产生path.repo：

"settings" : {
        ...
        "path" : {
          "logs" : "/usr/share/elasticsearch/logs",
          "home" : "/usr/share/elasticsearch"
        },
        ...
      },

我希望在路径中看到"repo" : ["/opt/elasticsearch/backup"]。

如文档中所述，您必须在path.repo文件中设置elasticsearch.yml。该文件位于图像的 / usr / share / elasticsearch / config / 目录中。因此，您的撰写文件应如下所示：

version: '3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4
    container_name: elasticsearch
    volumes:
      - elastic-data:/usr/share/elasticsearch/data
      - elastic-backup:/usr/share/elasticsearch/backup
      - ./elasticsearch/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
    ports:
      - 9200:9200
    environment:
      discovery.type: single-node
volumes:
  elastic-data:
  elastic-backup:

和您的elasticsearch.yml应该具有以下内容：

cluster.name: "docker-cluster"
network.host: 0.0.0.0

# minimum_master_nodes need to be explicitly set when bound on a public IP
# # set to 1 to allow single node clusters
# # Details: https://github.com/elastic/elasticsearch/pull/17288
# discovery.zen.minimum_master_nodes: 1
path.repo: ["/usr/share/elasticsearch/backup"]

启动容器后，我可以在http://127.0.0.1:9200/_nodes/?pretty响应中看到repo

"settings" : {
        "cluster" : {
          "name" : "docker-cluster"
        },
        "node" : {
          "name" : "3cUpSf-"
        },
        "path" : {
          "logs" : "/usr/share/elasticsearch/logs",
          "home" : "/usr/share/elasticsearch",
          "repo" : [
            "/usr/share/elasticsearch/backup"
          ]
        },

Answer 2

version: "3"
services:
  elasticsearch:
    image: elasticsearch:6.8.2
    environment:
      - 'path.repo=/opt/elasticsearch/backup'

这是我正在使用的 Docker Compose。我正在使用安装在卷下的外部路径。

我正在使用可以使用 docker network create --driver bridge apps 来创建的自定义网络

version: '3.7'
x-common-config: &common-config
  networks:
    - network
  restart: always
  ulimits:
    nproc: 65535
    nofile:
      soft: 65535
      hard: 65535
    memlock:
      soft: -1
      hard: -1

services:
  elasticsearch:
    <<: *common-config
    image: docker.elastic.co/elasticsearch/elasticsearch:7.6.1
    container_name: elasticsearch
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - node.name=elasticsearch
      - cluster.name=elasticsearch-cluster
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms2g -Xmx2g"
      - "path.repo=/usr/share/backup"    
    volumes:
      - data:/usr/share/elasticsearch/data
      - /mnt/elastic-backup:/usr/share/backup
  kibana:
    <<: *common-config
    image: docker.elastic.co/kibana/kibana:7.6.1
    container_name: kibana
    ports:
      - 5601:5601
    environment:
      SERVER_NAME: kibana
      XPACK.SECURITY.ENCRYPTIONKEY: <KEY>
    depends_on:
    - elasticsearch

volumes:
  data:
    driver: local

networks:
  network:

    external:
      name: apps
