그 밖의 tips

# root 이외 계정으로 실행해야만 하는 경우
runuser -u elasticsearch -- '/usr/share/elasticsearch/bin/elasticsearch'

• elasticsearch 같은 경우 package 로 설치한다면, config path 는 /etc/elasticsearch/ 가 된다.

elasticsearch vm 관련 에러

• limit - Elasticsearch: Max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] - Stack Overflow

wsl -d docker-desktop
echo "vm.max_map_count = 262144" >> /etc/sysctl.conf

이렇게 하고, container 를 새롭게 생성하자.
