Answer 1

you need to run this in your HOST terminal not the container:

sudo sysctl -w vm.max_map_count=262144

if you check the container logs you will see something like this:

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

please note also the above command will be reseted after rebooting your machine, you need to set the value in /etc/sysctl.conf to make it permenant.

Answer 2

Using the Docker images in production or local

The following requirements and recommendations apply when running Elasticsearch in Docker in production.

Set vm.max_map_count to at least 262144 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.

Linux

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

The vm.max_map_count setting must be set via docker-machine:

docker-machine ssh
sudo sysctl -w vm.max_map_count=262144

**Windows with Docker Desktop WSL 2 **

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
