Hi Marlah,
The error:
org.apache.camel.ResolveEndpointFailedException - Failed to resolve
endpoint: kamelet://my-custom-kamelet-action due to:
java.io.FileNotFoundException: Resource not found: classpath:
kamelets/my-custom-kamelet-action
means that the Kamelet is not found (not available) in the Camel Context.
By default Camel will search in the kamelets folder that located here:
src/
└─ main/
├─ java/...
└─ resources/
└─ kamelets/
When you build your JAR for production, those files need to end up in
classpath:kamelets/.
When you use for example main is runtime this location is set
automatically, but you can also do it programmatically:
main.configure().setKameletLocation("file:config/kamelets");
or via properties:
camel.kamelet.location=file:config/kamelets
Somehow it seems that the kamelet file isn't deployed to the resource
folder on the server/kubernetes. Best to investigate the jar file there.
Note it's also possible to fully load a Kamelet programmatically like this:
RoutesLoader loader = PluginHelper.getRoutesLoader(context);
Resource resource = ResourceHelper.fromString("my-custom-kamelet-action",
kameletAsString);
loader.loadRoutes(resource);
