第一次运行elasticsearch:8.11.1镜像，报错如下：

[root@master ~]# docker run --name es03 --net elastic -p 9200:9200 -it -m 1GB docker.elastic.co/elasticsearch/elasticsearch:8.11.1
docker: Error response from daemon: driver failed programming external connectivity on endpoint es03 (7e4d38400e1ee86e37bb258ccd4a74c9e863c065a46d79e1b197297d3b37b8f1): Bind for 0.0.0.0:9200 failed: port is already allocated.

 第二次运行报错同样：

[root@master ~]# docker run --name es01 --net elastic -p 9200:9200 -it -m 1GB docker.elastic.co/elasticsearch/elasticsearch:8.11.1
docker: Error response from daemon: Conflict. The container name "/es01" is already in use by container "b928b38936dd040ecc9e9d6afee38919627546c7c7650e7b6db7a331848d92b8". You have to remove (or rename) that container to be able to reuse that name.

停止运行中的docker镜像文件 

[root@master ~]# docker stop 2b965270912c 

 镜像文件查看

第三次运行elasticsearch:8.11.1镜像 

docker run --name es01 --net elastic -p 9200:9200 -it -m 1GB docker.elastic.co/elasticsearch/elasticsearch:8.11.1 

如下图表示已经运行成功，且保存下面文件内容。 

使用-m标志可以设置容器的内存限制。这样就不需要手动设置JVM大小。 

docker run -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -e ENROLLMENT_TOKEN="<token>" --name es01 -p 9200:9200 --net elastic -it docker.elastic.co/elasticsearch/elasticsearch:8.11.1 

--<token>---就是保存下来文件里的第一个密钥口令，如上图：Am-_WuVOCYKz*Q=dZyTd

docker run -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -e ENROLLMENT_TOKEN="Am-_WuVOCYKz*Q=dZyTd" --name es01 -p 9200:9200 --net elastic -it docker.elastic.co/elasticsearch/elasticsearch:8.11.1
