max virtual memory areas vm.max_map_count [65530] using docker over PLESK #322

Closed cibernicola closed 4 years ago

cibernicola commented 4 years ago

I'm trying to implement ELK version 7.6.1 With the serial configuration parameters and having modified the vm.max_map_count parameter to 262144

When running grep vm.max_map_count /etc/sysctl.conf after a reset the result is vm.max_map_count=262144.

But when I try to start the Docker instance, I get the error 1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Characteristics: 32GB of RAM available.

OS Distributor ID: Ubuntu Description: Ubuntu 18.04.4 LTS Release: 18.04 Codename: bionic

Plesk Obsidian 18.0.26 Docker extension for Plesk version 1.4.6-168

Any ideas or suggestions?

I understand that after a reboot sysctl vm.max_map_count is still 65530, ignoring what you put in /etc/sysctl.conf, is that right?

Does Plesk enable you to modify the system values? (e.g. can you try https://talk.plesk.com/threads/docker-elasticsearch-6-8-6-memory-error.354868/)

Hello The configuration is correct and permanent, as I mentioned in the first post, executing the sysctl vm.max_map_count the result is vm.max_map_count=262144

It seems that at some point "someone" is not able to either read or transmit this configuration.

Looks like a Docker for Plesk issue, or at the very least a question for the Plesk experts – would advise heading over to a Plesk forum for help. Can't help more I'm afraid.

I faced similar issue, and was able to run sudo sysctl -w vm.max_map_count=262144 on my linux distro where docker is running, the issue was fixed.

Definitely issue with Plesk. Maybe the user is changing in your case who has less permissions.

Closing as likely Plesk-related.

That was the first thing I did, all right, but apparently Plesk doesn't realize or admit it's modification from the outside. So the plesk-plugin docker combination for Plesk-Ubuntu and this ELK distribution are not compatible.
