The following requirements and recommendations apply when running Elasticsearch in Docker in production.
The vm.max_map_count kernel setting must be set to at least 262144 for production use.
How you set vm.max_map_count depends on your platform.
To view the current value for the vm.max_map_count setting, run:
grep vm.max_map_count /etc/sysctl.conf
vm.max_map_count=262144
To apply the setting on a live system, run:
sysctl -w vm.max_map_count=262144
To permanently change the value for the vm.max_map_count setting, update the value in /etc/sysctl.conf.
macOS with Docker for Mac
The vm.max_map_count setting must be set within the xhyve virtual machine:
From the command line, run:
screen ~/Library/Containers/com.docker.docker/Data/vms/0/tty
Press enter and use sysctl to configure vm.max_map_count:
sysctl -w vm.max_map_count=262144
To exit the screen session, type Ctrl a d.
Windows and macOS with Docker Desktop
The vm.max_map_count setting must be set via docker-machine:
docker-machine ssh
sudo sysctl -w vm.max_map_count=262144
The vm.max_map_count setting must be set in the docker-desktop container:
wsl -d docker-desktop sysctl -w vm.max_map_count=262144
