搭建集群的帖子有很多，但是似乎新版做了一些改动。

下面说一下我启动的步骤：先用如下命令启动第一个节点

 docker run --name es01 -it --privileged --memory="2g" \-p 9200:9200 -p 9300:9300 \-e cluster.name=my-application  \-e node.name=node-1  \-e cluster.initial_master_nodes='["node-1"]' \-e network.publish_host=你的ip \elasticsearch:8.17.0

然后进入容器生成token

docker exec -it es01 /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node

使用如下命令修改密码

docker exec -it es01 /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic -i

启动其他节点

docker run --name es02 -it --privileged --memory="2g" -d \-p 9200:9200 -p 9300:9300 \-e cluster.name=my-application  \-e node.name=node-2  \-e network.publish_host=你的ip \-e ENROLLMENT_TOKEN="eyJ2ZXIiOiI4LjEDguMTA1OjkyMDAiXSwiZmdyIjoiY2I3MWVmNTc2NjlmYjljZTRlMDZGQ4Yzk5OGUwMzY3MTcxYzM4N2Y3YSIsImtleSI6InVkdWtLSlVCUXM1NjNQWUhyblptOjJlOU5ndjZ2U3VtV3JGdHdZRlYzbFEifQ=="  \
elasticsearch:8.17.0
