hello @ismailbaskin thanks a lot for participating in the community. Can you confirm this is strictly needed ?

When only being user root and not group from docker it seems to work (have not double checked yet on kubernetes)

docker run --rm --privileged -u 0:1000 -it sonarqube bash
root@a2eaf9b9b0a8:/opt/sonarqube# id
uid=0(root) gid=1000(sonarqube) groups=1000(sonarqube)
root@a2eaf9b9b0a8:/opt/sonarqube# sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144
root@a2eaf9b9b0a8:/opt/sonarqube#
