我正在开发一个使用elasticsearch的Django项目.Django版本是1.9.2，python版本是2.7。我在Docker容器中部署项目，该容器通常以root用户身份运行进程。映像已成功构建，除弹性搜索外，一切正常。我得到了

尝试启动ElasticSearch时出现

错误，并且似乎没有办法绕过它。 ElasticSearch无法以root身份运行的原因是什么？在docker容器内部，事物被隔离，根进程被认为是安全的。

Answer 1

不建议以root身份运行elasticsearch。对于临时解决方案，您可以通过在下面的行中启用属性 es.insecure.allow.root 来运行。

bin/elasticsearch -Des.insecure.allow.root=true
