Question

我已经使用舵图在Kubernetes上安装了elasticsearch 。我需要启用xpack安全性，我需要使用elasticsearch-certutil创建证书。我在kubernetes上找不到它。

我现在遇到的错误

这是我的配置esConfig：

elasticsearch.yml: |
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /usr/share/elasticsearch/config/certs/ca.p12
xpack.security.transport.ssl.truststore.path: /usr/share/elasticsea/config/certs/ca.p12

xpack.security.http.ssl.enabled：true xpack.security.http.ssl.truststore.path：/usr/share/elasticsearch/config/certs/ca.p12 xpack.security.http.ssl.keystore.path：/usr/share/elasticsearch/config/certs/ca.p12

我使用kubectl exec -it elasticsearch-master-0-/ bin / bash进入容器并在/ usr / share / elasticsearch / certs的确切路径中生成证书

由于您正在使用helm charts，因此需要在模板中设置所有这些内容。

首先，您应该熟悉https://github.com/helm/charts/tree/master/stable/elasticsearch

第二，您需要检查elasticsearch-master-2之一的豆荚出了什么问题，因为它是CrashLoopBackOff。您可以使用kubectl describe pods elasticsearch-master-2并在底部检查事件。

关于Xpack和Enabling elasticsearch interal monitoring：

需要版本6.3+和定义的标准非oss存储库。从6.3开始，Xpack是部分免费的，默认情况下已启用。您需要设置一个新的配置来启用这些内部指标的收集。（https://www.elastic.co/guide/en/elasticsearch/reference/6.3/monitoring-settings.html）

要通过此舵图进行此操作，请覆盖以下三个更改：
image.repository: docker.elastic.co/elasticsearch/elasticsearch
cluster.xpackEnable: true
cluster.env.XPACK_MONITORING_ENABLED: true
注意：要查看这些更改，您需要将kibana存储库更新为image.repository: docker.elastic.co/kibana/kibana，而不是oss版本

您还应该阅读Get a Shell to a Running Container，这说明您可以连接到pod。

在您的示例中使用kubectl exec -it elasticsearch-master-0 -- /bin/bash

kuberenetes上的bin / elasticsearch在哪里
