docker ELK 堆栈的 Search-guard 插件在连接到 elasticsearch 集群时出现问题

Question

几分钟前，我克隆了 search guard branch from here，并且我完全按照 README 所说的去做。

在 docker-compose up -d 之后，所有服务都在工作，但 elasticsearch_1 每隔几秒记录一个错误：

elasticsearch_1 | [2018-09-14T08:59:49,614][ERROR][c.f.s.a.BackendRegistry ] Not yet initialized (you may need to run sgadmin)

之后我运行docker-compose exec -T elasticsearch bin/init_sg.sh，输出：

Search Guard Admin v6

Contacting elasticsearch cluster 'elasticsearch' and wait for YELLOW clusterstate ...
    ERR: Timed out while waiting for a green or yellow cluster state.
    * Try running sgadmin.sh with -icl (but no -cl) and -nhnv (If that works you need to check your clustername as well as hostnames in your TLS certificates)
    * Make also sure that your keystore or PEM certificate is a client certificate (not a node certificate) and configured properly in elasticsearch.yml
    * If this is not working, try running sgadmin.sh with --diagnose and see diagnose trace log file)
    * Add --accept-red-cluster to allow sgadmin to operate on a red cluster.

我猜想 sgadmin 无法连接到 elasticsearch 集群，但我按照 README 所说的做了一切。

任何关于如何解决这个问题的建议？感谢您的回答。

我已经解决了这个问题。您的产品运行良好。我在索引 win Kibana 时遇到错误，它使 elasticsearch cluster 状态为红色 - 从不为黄色。

如果您想将 sgadmin 连接到 elasticsearch cluster 而无需等待黄色状态，请使用行：--accept-red-cluster in init_sg.sh脚本：

#!/bin/sh
plugins/search-guard-6/tools/sgadmin.sh \
    -cd config/sg/ \
    -ts config/sg/truststore.jks \
    -ks config/sg/kirk-keystore.jks \
    -nhnv \
    -icl \
    --accept-red-cluster

然后一切正常，Kibana 会告诉你为什么你有 RED 状态 - 在我的例子中是 kibana 索引问题。
