3.5. 在开发模式下运行 Camel K 集成
您可以从命令行在 OpenShift 集群上以开发模式运行 Camel K 集成。使用开发模式,您可以快速迭代开发中的集成,并对代码获得快速反馈。
当您使用 --dev
选项指定 kamel run
命令时,这会立即在云中部署集成,并在终端中显示集成日志。然后,您可以更改代码,并查看更改会自动应用到 OpenShift 上的远程集成 Pod。终端会自动显示云中的远程集成的所有重新部署。
注意
在开发模式中由 Camel K 生成的工件与生产环境中运行的工件相同。开发模式的目的是加快开发速度。
前提条件
- 设置您的 Camel K 开发环境.
- 您必须具有用 Java 或 YAML DSL 编写的 Camel 集成。
流程
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
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
使用
--dev
输入kamel run
命令,以在 OpenShift 云中以开发模式运行您的集成。下面显示了一个简单的 Java 示例:$ kamel run HelloCamelK.java --dev Condition "IntegrationPlatformAvailable" is "True" for Integration hello-camel-k: test/camel-k Integration hello-camel-k in phase "Initialization" Integration hello-camel-k in phase "Building Kit" Condition "IntegrationKitAvailable" is "True" for Integration hello-camel-k: kit-c49sqn4apkb4qgn55ak0 Integration hello-camel-k in phase "Deploying" Progress: integration "hello-camel-k" in phase Initialization Progress: integration "hello-camel-k" in phase Building Kit Progress: integration "hello-camel-k" in phase Deploying Integration hello-camel-k in phase "Running" Condition "DeploymentAvailable" is "True" for Integration hello-camel-k: deployment name is hello-camel-k Progress: integration "hello-camel-k" in phase Running Condition "CronJobAvailable" is "False" for Integration hello-camel-k: different controller strategy used (deployment) Condition "KnativeServiceAvailable" is "False" for Integration hello-camel-k: different controller strategy used (deployment) Condition "Ready" is "False" for Integration hello-camel-k Condition "Ready" is "True" for Integration hello-camel-k [1] Monitoring pod hello-camel-k-7f85df47b8-js7cb ... ...
