Issue

1. docker-compose up with docker-compose.yaml file
2. but when docker ps find no elaticsearch container, only kibana and cerebro
3. exec docker ps -a find elasticsearch conbtainer is EXITED status

   [root@localhost ~]# docker ps -a
   CONTAINER ID        IMAGE                                                 COMMAND                  CREATED             STATUS                       PORTS                    NAMES

4. check EXITED containber logs by docker logs 6826362e507e, find that:

   ERROR: [1] bootstrap checks failed
   [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

[Resolution]

• check current

  [root@localhost ~]# sysctl -a|grep vm.max_map_count
  vm.max_map_count = 65530

• modify

  [root@localhost ~]# sysctl -w vm.max_map_count=262144
  vm.max_map_count = 262144

• to overwrite permenently, add to last rom

  [root@localhost ~]# vim /etc/sysctl.conf   
  vm.max_map_count=262144

• cancel the last docker compose

  [root@localhost ~]# docker-compose down -v
  Stopping cerebro ... done
  Stopping kibana7 ... done
  Removing es7_02  ... done
  Removing es7_01  ... done
  Removing cerebro ... done
  Removing kibana7 ... done
  Removing network root_es7net
  Removing volume root_es7data1
  Removing volume root_es7data2

• docker-compose up again
