1.2.2.2. 确定 Kamelet 的配置参数

在 Kamelet Binding 中，当添加对 Kamelet 的引用时，您可以指定 Kamelet 的名称并配置 Kamelet 的参数。

前提条件

您在工作命名空间或集群范围安装了 Camel K operator。

流程

要确定 Kamelet 的名称和参数：

在终端窗口中，登录到您的 OpenShift 集群。
打开 Kamelet 的 YAML 文件：
oc describe kamelets/<kamelet-name>
例如，如果当前命名空间中安装 Camel K operator，要查看 ftp-source Kamelet 的代码，请使用以下命令：
oc describe kamelets/ftp-source
如果以 cluster-mode 的形式安装 Camel K operator，请使用以下命令：
oc describe -n openshift-operators kamelets/ftp-source

在 YAML 文件中，向下滚动到 spec.definition 部分（以 JSON-schema 格式编写），以查看 Kamelet 的属性列表。在部分的末尾，必填字段列出了在引用 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。本节提供了所有 Kamelet 配置属性的详情。此 Kamelet 的必要属性是 connectionHost,connectionPort,username,password, 和 directoryName ：
