When using Docker Compose, you might encounter the following error: 
max virtual memory areas vm.max_map_count 65530 is too low, increase to at least 262144
This error indicates that the current setting for vm.max_map_count is too low for the application you are trying to run inside a Docker container. This setting controls the maximum number of memory map areas a process may have.

​
Fix

Increase the VM max map count to the required value: 
sudo sysctl -w vm.max_map_count=262144
This change is applied immediately but is not persistent across reboots. To make it permanent, add vm.max_map_count=262144 to /etc/sysctl.conf and run sudo sysctl -p to reload.
