I want to access the logs of elasticsearch while it's running in a docker container. The goal is to keep track of possible errors while indexing documents.  
I'm using the following docker-compose and I run it with _sudo docker-compose up_

```auto
version: '3.3'
services:
   
  elasticsearch1:
    restart: always
    image: elasticsearch:${ELK_VERSION}
    ports:
      - ${ES_PORT_HTTP}:9200
    volumes:
      - ./elasticsearch/data1:/usr/share/elasticsearch/data
      - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - ./elasticsearch/logs:/usr/share/elasticsearch/logs
    environment:
      - node.name=elasticsearch1
      - discovery.seed_hosts=elasticsearch2
      - cluster.initial_master_nodes=elasticsearch1, elasticsearch2
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS: -Xmx1g -Xms1g"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    networks:
      - ni-network

  elasticsearch2:
    restart: always
    image: elasticsearch:${ELK_VERSION}
    volumes:
      - ./elasticsearch/data2:/usr/share/elasticsearch/data
      - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
    environment:
      - node.name=elasticsearch2
      - discovery.seed_hosts=elasticsearch1
      - cluster.initial_master_nodes=elasticsearch1, elasticsearch2
      - "ES_JAVA_OPTS: -Xmx1g -Xms1g"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    networks:
      - ni-network

networks:
  ni-network:
    external: true

```

Is it the right way to proceed ?  
I can't start this compose because of the following :

```auto
elasticsearch1_1_9fc8d5261881 | Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]
