image: elasticsearch:7.12.0
container_name: es01
environment:
- "discovery.type=single-node"
- "ES_JAVA_OPTS=-Xmx256m -Xms256m"
- xpack.security.enabled=true
- xpack.license.self_generated.type=basic
- xpack.security.transport.ssl.enabled=true
volumes:
- /opt/docker/elasticsearch/data:/usr/share/elasticsearch/data:rw
- /opt/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins
- /opt/docker/elasticsearch/logs:/usr/share/elasticsearch/logs
ports:
- "9200:9200"
- "9300:9300"

driver: bridge继部署单机，快速使用后，设置密码只需要加上xpack相关配置即可
重启容器（docker-compose restart）后，进入容器生成密码
# 进入容器
root# docker exec -it es01 /bin/bash
# 在容器内，执行自动生成密码命令
[root@8b97a00d4223 elasticsearch]# bin/elasticsearch-setup-passwords auto
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.
The passwords will be randomly generated and printed to the console.
Please confirm that you would like to continue [y/N]y
Changed password for user apm_system
PASSWORD apm_system = ***
Changed password for user kibana_system
PASSWORD kibana_system = ***
Changed password for user kibana
PASSWORD kibana = ***
Changed password for user logstash_system
PASSWORD logstash_system = ***
Changed password for user beats_system
PASSWORD beats_system = ***
Changed password for user remote_monitoring_user
PASSWORD remote_monitoring_user = ***
Changed password for user elastic
PASSWORD elastic = ***至此密码已经设置成功，可以使用对应用户名和密码访问了，***为自动生成的密码，记住即可。
若要重置密码，修改配置，注释掉这一行配置后重启容器：
#- xpack.security.enabled=true然后访问
curl -XGET "http://localhost:9200/_cat/indices?pretty" -H 'Content-Type: application/json'会出现一个索引： .security-7 ，删除即可
curl -XDELETE http://localhost:9200/.security-7
