Docker启动Elastic Search报错 ERROR: [1] bootstrap checks failed

1. 报错

ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

原因：如果是pull 官方镜像后直接启动，是没有配置Elastic Search的，所以需要添加一些配置信息。

注：博主这里配置过句柄数，如果没有配置过，可能也会报句柄数过小的错误。

2. 解决办法

找到elasticsearch.yml 文件：
注意：如果你有多个elastic search镜像或者容器，会查询到多个文件，这个需要一一尝试才能找到对应的配置文件，所以建议把所有的配置文件都添加上下面的内容。。。

在文件末尾添加：

bootstrap.system_call_filter: false
cluster.initial_master_nodes: ["node-1"]

重新启动测试：

docker start  容器名称/ID

完！
