1.2.2.2. 确定 Kamelet 的配置参数

打开 Kamelet 的 YAML 文件：

oc describe kamelets/<kamelet-name>

例如，查看 ftp-source Kamelet 的代码（如果已在当前命名空间中安装了 Camel K operator），请使用以下命令：

oc describe kamelets/ftp-source

如果 Camel K Operator 以 cluster-mode 的形式安装，则使用以下命令：

oc describe -n openshift-operators kamelets/ftp-source

在 YAML 文件中，向下滚动到 spec.definition 部分（使用 JSON-schema 格式写入），以查看 Kamelet 的属性列表。在部分末尾，required 字段列出了在引用 Kamelet 时必须配置的属性。

例如，以下代码是 ftp-source Kamelet 的 spec.definition 部分的摘录。本节详细介绍了 Kamelet 的所有配置属性。此 Kamelet 的必要属性是 connectionHost、connectionPort、username、password 和 directoryName ：
