Docker with SLM automatically snapshot

[toaitrancom (Toai Tran)]

Hello,

I'm not the expert, I have followed Elasticsearch's docker documentation, and it worked!

Here's my docker-compose.yml file

    version: '2.2'
services:
  dropbot-es01:
    restart: always
    image: docker.elastic.co/elasticsearch/elasticsearch:7.6.1
    container_name: dropbot-es01
    environment:
      - node.name=dropbot-es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=dropbot-es02,dropbot-es03
      - cluster.initial_master_nodes=dropbot-es01,dropbot-es02,dropbot-es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data01:/usr/share/elasticsearch/data
    ports:
      - 127.0.0.1:9200:9200
    networks:
      - elastic
  dropbot-es02:
    restart: always
    image: docker.elastic.co/elasticsearch/elasticsearch:7.6.1
    container_name: dropbot-es02
    environment:
      - node.name=dropbot-es02
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=dropbot-es01,dropbot-es03
      - cluster.initial_master_nodes=dropbot-es01,dropbot-es02,dropbot-es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data02:/usr/share/elasticsearch/data
    networks:
      - elastic
  dropbot-es03:
    restart: always
    image: docker.elastic.co/elasticsearch/elasticsearch:7.6.1
    container_name: dropbot-es03
    environment:
      - node.name=dropbot-es03
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=dropbot-es01,dropbot-es02
      - cluster.initial_master_nodes=dropbot-es01,dropbot-es02,dropbot-es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data03:/usr/share/elasticsearch/data
    networks:
      - elastic

volumes:
  data01:
    driver: local
  data02:
    driver: local
  data03:
    driver: local

networks:
  elastic:
    driver: bridge

Then, I want to use the SLM feature, where I can back up my entire indexes automatically.

I have used the PUT request to _snapshot endpoint, but it didn't work.

My CURL response

    {
  "error" : {
    "root_cause" : [
      {
        "type" : "repository_exception",
        "reason" : "[backup_elasticsearch] location [/home/backup_elasticsearch] doesn't match any of the locations specified by path.repo because this setting is empty"
      }
    ],
    "type" : "repository_exception",
    "reason" : "[backup_elasticsearch] failed to create repository",
    "caused_by" : {
      "type" : "repository_exception",
      "reason" : "[backup_elasticsearch] location [/home/backup_elasticsearch] doesn't match any of the locations specified by path.repo because this setting is empty"
    }
  },
  "status" : 500
}

Can you please help me in setting the repo.path in docker-compose.yml file?

And do I need to set path.repo for every cluster or just the first one?

Thank you
