kamel run examples/Sample.java
```

During your first run you may see your console stuck with the following message:

```
integration "sample" created
integration "sample" in phase Waiting For Platform
```

NOTE: It will take some time for your integration to get started for the first time. This is because the camel-k operator has to pull and cache the camel-k builder images into the cluster’s registry.

You can follow this process by watching the pods in the namespace where the operator is running:

```
kubectl get pods -w
```

you shold see something like:

```
$ kubectl get pods -w
NAME READY STATUS RESTARTS AGE
camel-k-cache 0/1 Completed 0 3m29s
camel-k-groovy-builder 1/1 Running 0 32s
camel-k-jvm 0/1 Completed 0 61s
camel-k-jvm-builder 0/1 Completed 0 2m13s
camel-k-operator-587b579567-fkz54 1/1 Running 1 43m
camel-k-groovy 0/1 Pending 0 0s
camel-k-groovy 0/1 ContainerCreating 0 0s
camel-k-groovy 1/1 Running 0 2s
camel-k-groovy 0/1 Completed 0 4s

camel-k-kotlin-builder 0/1 Pending 0 0s
camel-k-kotlin-builder 0/1 ContainerCreating 0 0s
camel-k-groovy-builder 0/1 Completed 0 75s
...
```

after a couple of minutes you can see your integration runnning. To see the output log of your integration container get thet pod id:

```
kubectl get pods | grep sample
sample-67699569c4-724dv 1/1 Running 0 15m
```

And then see the logs using:

```
kubectl logs -f sample-67699569c4-724dv
```

An output like this should appear:

```
