How to use the official docker elasticsearch container?

Question

I have the following Dockerfile:

FROM docker.elastic.co/elasticsearch/elasticsearch:5.4.0
RUN elasticsearch
EXPOSE 80

I think the 3rd line

Answer 1

Your container is auto exiting because of insufficient virtual memory, by default to run an elastic search container your memory should be a min of 262144 but if you run this command sysctl vm.max_map_countand see it will be around 65530. Please increase your virtual memory count by using this command sysctl -w vm.max_map_count=262144 and run the container again docker run IMAGE IDthen you should have your container running and you should be able to access elastic search at port 9200 or 9300
