docker - Docker Swarm中的Elasticsearch 6.4:为Elasticsearch进程请求了内存锁定，但内存未锁定

Question

我正在尝试在Docker Swarm中运行Elasticsearch。
这是我的docker-compose文件:

version: '3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.4.2
    networks:
      - swarm_network
    ports:
      - "9200:9200"
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - xpack.security.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    deploy:
      mode: replicated
      replicas: 1
      resources:
        limits:
          memory: 1000M

我收到此错误:
错误:[1]引导检查失败
[1]:请求 flex 搜索过程进行内存锁定，但内存未锁定

有谁知道为什么这个错误以及如何解决呢？

设置LimitMEMLOCK=infinity到docker.service单元对我来说工作正常(在ubuntu服务器1804上运行的docker 18.06.1-ce)

(来源:ozswang on https://github.com/FusionAuth/fusionauth-containers/issues/1)

echo -e "[Service]\nLimitMEMLOCK=infinity" | SYSTEMD_EDITOR=tee systemctl edit docker.service

systemctl daemon-reload

systemctl restart docker
