network.host setting for Docker running ElasticSearch

Question

I am running a docker in my ubuntu host with the following:

docker run -d --rm -p 9200:9200 -p 9300:9300 --name elasticsearch6.6.1 docker.elastic.co/elasticsearch/elasticsearch:6.6.1

Later on when I query like so, I get failure:

curl 'http://localhost:9200/?pretty'

The failure looks like so:

curl 'http://localhost:9200/?pretty'

[command]/bin/bash --noprofile --norc /home/vsts/work/_temp/dcac22e9-6b6f-443b-8497-c093dd6bb804.sh

curl: (56) Recv failure: Connection reset by peer

So, my question is:

How do I start elasticsearch on docker and publish the ports 9200 and 9300 to the host?
Is network.host=_ site _ setting required?

Thanks,

Could you show result of docker logs elasticsearch6.6.1 or are you sure that it properly set up? — ttomalak

After reviewing the image that you have mentioned, please check the logs of the container as you might have an error similar to this:

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

In my case solved by: sysctl -w vm.max_map_count=262144 then when i try the curl command it works as expected:

curl 'http://localhost:9200/?pretty'
