Hi Team,

on the Ubuntu 20.04 Multi Node playground we don’t have permission to modify the value of vm.max_map_count as root.

sysctl -w vm.max_map_count=2097152

Hi,

I want to try install Elasticsearch for testing and the service won’t start if I don’t set the value of
vm.max_map_count to 2097152 .

Hi @fethi.amari ,

Please try the below steps, let me know if this works.

sudo apt-get update 
sudo apt-get install -y gnupg gnupg2 ca-certificates
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https

Hi @Dinesh_Kodekloud

Thank you for the steps,

the Elasticsearch Service won’t start when I configured as a cluster as shown by the below error.

Please give us the permission to modify this parameter.

2022-05-05T11:02:50,571][ERROR][o.e.b.Bootstrap          ] [node01] node validation exception

Hi @fethi.amari ,

Our apologies for the inconvenience. It seems we can’t change such kernel parameters of the DevOps playgrounds as of now. Please consider using the cloud playgrounds ( AWS or Azure).

Let us know if we can help you in any way.
