bootstrap checks failed at docker-compose up

[DaniSchenk]

When I try to start my elk container I get the following error message:
node validation exception
bootstrap checks failed
max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

docker-compose.yml:

elk2:
  image: "sebp/elk:es500_l500_k500"
  ports:
    - "5601:5601"
    - "9200:9200"
    - "5044:5044"

console output:

I fixed the error by running sysctl -w vm.max_map_count=262144 in terminal (Linux/Ubuntu).
Then I created a file named 60-elasticsearch.conf and placed it in /etc/sysctl.d/ with the following content

vm.max_map_count=262144

Creating this .conf file makes the change permanent and still present after server restarts, right?

Yep, see #79 and http://elk-docker.readthedocs.io/#troubleshooting.
