Modify the parameters according to the actual situation.

docker run -d --restart=always --user=root \
    --privileged=true \
    --name elasticsearch \
    -p 9200:9200 \
    -p 9300:9300 \
    --ulimit nofile=65536:65536 \
    -v "/data/elasticsearch/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml" \
    -v "/data/elasticsearch/data":/usr/share/elasticsearch/data \
