Question

Helm 版本：“v3.1.1”

helm get release 输出

掌舵状态metricbeat 名称：metricbeat 最后部署：2020 年 4 月 30 日星期四 10:05:32 命名空间：默认 状态：已部署 修订：1

描述错误：无法连接到elasticsearch，部署的configmap不包含用户名：和密码输入。

重现步骤：

1. 在 elasticsearch 中启用 xpack
2. 运行 - helm install metricbeat elastic/metricbeat --set imageTag=7.6.2 --values metrics.yaml

metrics.yaml

    output.elasticsearch:
      hosts: '${ELASTICSEARCH_HOSTS:elasticsearch-master:9200}'

预期行为：应该使用用户名和密码连接到 es 没有问题。

提供日志和/或服务器输出（如果相关）：

   pipeline/output.go:100 Failed to connect to backoff(elasticsearch(http://elasticsearch-master:9200)): 401 Unauthorized: {"error":{"root_cause":[{"type":"security_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}

任何其他上下文：

我能够使用相同的凭据连接弹性搜索，并且它也适用于 Kibana 登录。

Answer 1

我是Elastic Helm charts的维护者。

由于最近的重构，记录在 Git 存储库主分支上的值 daemonset.xxx 和 deployment.xxx 与当前发布的图表版本不兼容。

如果您想安装当前发布的版本 (7.6.2)，您可以在 README from 7.6.2 release 上找到要使用的值。

如果您想部署即将发布的下一个版本并将使用daemonset.xxx 和deployment.xxx 值，您可以克隆存储库并使用installation instructions from 7.7 branch。

PS：正如评论中提到的，请注意 Elastic 图表还不支持 Helm v3，我们仍然建议使用 Helm v2。
