3.5. 開発モードでの Camel K インテグレーションの実行

手順

1. 以下の例のように、oc クライアントツールを使用して OpenShift クラスターにログインします。

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

2. 以下の例のように、Camel K Operator が稼働していることを確認します。

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

3. kamel run コマンドと --dev を入力し、クラウドの OpenShift にて開発モードでインテグレーションを実行します。以下は、簡単な Java の例になります。

   $ 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
