3.4. 运行 Camel K 集成

流程

1. 使用 oc 客户端工具登录到 OpenShift 集群，例如：

   $ oc login --token=my-token --server=https://my-cluster.example.com:6443

2. 确保 Camel K Operator 正在运行，例如：

   $ oc get pod
   NAME                               READY   STATUS    RESTARTS   AGE
   camel-k-operator-86b8d94b4-pk7d6   1/1     Running   0          6m28s

3. 输入 kamel run 命令，在 OpenShift 上的云中运行您的集成。例如：

   Java 示例

   $ kamel run HelloCamelK.java
   integration "hello-camel-k" created

   YAML 示例

   $ kamel run hello.camelk.yaml
   integration "hello" created

4. 输入 kamel get 命令检查集成状态：

   $ kamel get
   NAME       PHASE           KIT
   hello      Building Kit    myproject/kit-bq666mjej725sk8sn12g

   当集成首次运行时，Camel K 为容器镜像构建集成套件，这会下载所有必要的 Camel 模块并将其添加到镜像类路径中。

5. 再次输入 kamel get 来验证集成是否正在运行：

   $ kamel get
   NAME       PHASE   KIT
   hello      Running myproject/kit-bq666mjej725sk8sn12g

6. 输入 kamel log 命令，将日志输出到 stdout ：

   $ kamel log hello
