注意:此问题特定于Swisscom提供的Elasticsearch服务
问题:(又称tl;dr)
要获得官方的Kibana docker 容器以连接到Swisscom Elasticsearch Service，需要什么配置？
背景:
直到大约一年前，Swisscom public cloud在一次服务中提供了完整的ELK堆栈(Elasticsearch，Logstash，Kibana)。停止提供该服务后，Swisscom仅仅提供Elasticsearch服务即可取代它，并要求客户通过提供的CloudFoundry build_packs(Kibana，Logstash)设置自己的Kibana和Logstash解决方案。在此处讨论了迁移建议:https://ict.swisscom.ch/2018/04/building-the-elk-stack-on-our-new-elasticsearch/
最近，对基于Swisscom基于CloudFoundry的PaaS产品上运行应用程序的底层操作系统(称为“堆栈”)进行了升级。前面提到的build_packs现在已过时，并已由Swisscom宣布已弃用。现在的建议是转到此处讨论的通用Docker container provided by Elastic:https://github.com/swisscom/kibana-buildpack/issues/3
我尝试了什么:
CloudFoundry通常可以很好地与Docker容器配合使用，并且整个过程应该与为Docker容器提供一些有效的配置一样简单。我当前的Kibana的manifest.yml看起来像这样，但是Kibana应用程序最终无法连接:
---
applications:
- name: kibana-test-example
docker:
image: docker.elastic.co/kibana/kibana:6.1.4
memory: 4G
disk_quota: 5G
services:
- elasticsearch-test-service
env:
SERVER_NAME: kibana-test
ELASTICSEARCH_URL: https://abcdefghijk.elasticsearch.lyra-836.appcloud.swisscom.com
ELASTICSEARCH_USERNAME: username_provided_by_elasticsearch_service
ELASTICSEARCH_PASSWORD: password_provided_by_elasticsearch_service
XPACK_MONITORING_ENABLED: true
附加信息:
Swisscom提供的Elasticsearch Service当前在
6.1.3版本上运行。据我所知，它已经安装了x-pack。您遇到什么错误？
我对配置进行了一些尝试，并看到了不同的错误，其中大多数似乎与对Elasticsearch Service的身份验证失败有关。
这是一些示例性的初始日志输出(但是，严重的是，您需要一个正在运行的Kibana才能读取该信息...)

实际相关的错误消息似乎是这样的:

我尝试将
XPACK_SECURITY_ENABLED: false设置为其他地方推荐的值，以及设置实际的SERVER_HOST，这似乎使情况变得更糟。我非常感谢一个使用现有Kibana docker镜像连接到Swisscom提供的Elasticsearch Service的人的工作示例。
最佳答案
可能是您混淆了用户名和密码吗？当我检查我的服务密钥密码位于用户名之前时，这可能会导致您身边的复制粘贴错误:
cf service-key myece mykey|grep kibana_system
"kibana_system_password": "aKvOpMVrXGCJ4PJht",
"kibana_system_username": "aksTxVNyLU4JWiQOE6V",
我尝试用您的manifest.yml推送Kibana，它在我的情况下非常有效。
Swisscom还更新了有关如何在Docker上使用Kibana和Logstash的文档:
