连接到 zookeeper 时的 kafka 问题 (kubernetes-kafka:1.0-10.2.1)
kafka issue while connecting to zookeeper (kubernetes-kafka:1.0-10.2.1)
我用这个文档创建kafkahttps://kow3ns.github.io/kubernetes-kafka/manifests/
能够创建 zookeeper，面临创建 kafka.getting 连接 zookeeper 错误的问题。
这是我用来创建的清单
对于卡夫卡：

kafka deployed manifest
根据您的屏幕截图，您的 Kafka 和 Zookeeper 部署 运行 在 kaf 命名空间中，大概您已经手动设置并在该命名空间中应用配置？ Kafka 或 Zookeeper YAML 文件均未在元数据中明确声明命名空间，因此将在创建时部署到活动命名空间。
无论如何，您拥有的 Kafka 部署 YAML 已被硬编码为假设 Zookeeper 已在 default 命名空间中设置，具有以下行：
--override zookeeper.connect=zk-cs.default.svc.cluster.local:2181 \
将其更改为：
--override zookeeper.connect=zk-cs.kaf.svc.cluster.local:2181 \
它应该可以连接。是否通过下载和本地编辑 YAML 文件等
或者将 Zookeeper 部署到 default 命名空间。
我还建议查看其他选项，例如 Bitnami Kafka Helm charts，它根据需要使用 Kafka 部署 Zookeeper，管理大部分连接细节并允许更轻松的自定义。它也保持更新。
我用这个文档创建kafkahttps://kow3ns.github.io/kubernetes-kafka/manifests/
能够创建 zookeeper，面临创建 kafka.getting 连接 zookeeper 错误的问题。
这是我用来创建的清单 对于卡夫卡：

Crash-Loop-Kafka kafka deployed manifest
根据您的屏幕截图，您的 Kafka 和 Zookeeper 部署 运行 在 kaf 命名空间中，大概您已经手动设置并在该命名空间中应用配置？ Kafka 或 Zookeeper YAML 文件均未在元数据中明确声明命名空间，因此将在创建时部署到活动命名空间。
无论如何，您拥有的 Kafka 部署 YAML 已被硬编码为假设 Zookeeper 已在 default 命名空间中设置，具有以下行：
--override zookeeper.connect=zk-cs.default.svc.cluster.local:2181 \
将其更改为：
--override zookeeper.connect=zk-cs.kaf.svc.cluster.local:2181 \
它应该可以连接。是否通过下载和本地编辑 YAML 文件等
或者将 Zookeeper 部署到 default 命名空间。
我还建议查看其他选项，例如 Bitnami Kafka Helm charts，它根据需要使用 Kafka 部署 Zookeeper，管理大部分连接细节并允许更轻松的自定义。它也保持更新。
