ElasticSearch in Windows docker image vm max map count

Question

I am new to Docker and Elasticsearch. I am using a Windows 7 machine. I am using docker-compose up to bring up the docker container. My yml file has

elasticsearch:   image: elasticsearch:5.1.1   environment:     ES_JAVA_OPTS: "-Xms1g -Xmx1g" 

along with other linked images.
I am using docker to bring up the elasticsearch image and when I do so I get the following error

[36melasticsearch_1   |←[0m ERROR: bootstrap checks failed [36melasticsearch_1   |←[0m max virtual memory areas vm.max_map_count [65530]  is too low, increase to at least [262144] [36melasticsearch_1   |←[0m [2017-02-08T11:06:51,752][INFO ][o.e.n.Node 

I googled for a solution and everywhere they suggest to use sudo sysctl vm.max_map_count=262144, but in Windows sysctl is not available. No clear steps are given for Windows.

Some other Docker images are up and running on my machine so Docker is working.

Can someone give any clues to solve this issue?

Answer 1

I have been stuck for months on this problem, the solution is launch the following commands on cmd.exe (try Powershell or Bash if cmd doesn't work), as stated in the official Elasticsearch documentation:

1) wsl -d docker-desktop 2) sysctl -w vm.max_map_count=262144 

And you are ready to start Elasticsearch!
