Elasticsearch docker container: max virtual memory error

Question

I've pulled the Elasticsearch docker image and ran it according to the instructions here .

However, the processes exits due to the following error:

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

• Isn't a docker container supposed to ready to run, without issues?
• This site suggests sysctl vm.max_map_count 262144 . Is this safe?

Answer 1

To resolve Max virtual memory low error you need to use the below command:

sysctl -w vm.max_map_count=262144

But this setting will reset to its original value, after the host reboots. To make this change permanent you need to add vm.max_map_count to 262144 in /etc/sysctl.conf
