ubuntu 24.04 provides a default 'ubuntu' user. best practices I found suggest to just remove it before adding our own user.

groupadd -g 1000 elasticsearch && \\
useradd --uid 1000 --gid 1000 --home-dir /usr/share/elasticsearch --create-home elasticsearch && \\
usermod -aG root elasticsearch && \\
chown -R 0:0 /usr/share/elasticsearch
