Chapter 1. Testing Camel K integration locally This chapter provides details on how to use Camel jBang to locally test a Camel K integration. Section 1.1, "Using Camel jBang to locally test a Camel K integration" 1.1. Using Camel jBang to locally test a Camel K integration Testing is one of the main operations performed repeatedly while building any application. With the advent of Camel JBang , we have a unified place that can be used to perform testing and fine tuning locally before moving to a higher environment. Testing or fine tuning an integration directly connected to a Cloud Native environment is a bit cumbersome. You must be connected to the cluster, or alternatively, you need a local Kubernetes cluster running on your machine (Minikube, Kind etc). Most of the time, the aspects inherent to the cluster fine tuning are arriving late in the development. Therefore, it is good to have a ligther way of testing our applications locally and, move to a deployment stage where we can apply that tuning, typical to a cloud native environment. kamel local is the command used to test an Integration locally in the past. However, it overlaps the effort done by Camel community to having a single CLI that is used to test locally any Camel application independently, where this is going to be deployed. 1.1.1. Camel JBang installation Firstly, we need to install and get familiar with jbang and camel CLIs. You can follow the official documentation about Camel JBang to install the CLIs to your local environment. After this, we can see how to test an Integration for Camel K with Camel JBang. 1.1.2. Simple application development The first application we develop is a simple one, and it defines the process you must follow when testing any Integration that is eventually deployed in Kubernetes via Camel K. verify the target version of Camel in your Camel K installation. With this information we can ensure to test locally against the same version that we will be later deploying in a cluster. The commands above are useful to find out what is the Camel version used by the runtime in your cluster Camel K installation. Our target is Camel version 3.18.3. The easiest way to initialize a Camel route is to run camel init command: At this stage, we can edit the file with the logic we need for our integration, or, simply run it: A local java process starts with a Camel application running. No need to create a Maven project, all the boilerplate is on Camel JBang! However, you may notice that the Camel version used is different from the one we want to target. This is because your Camel JBang is using a different version of Camel. No worry, we can re-run this application but specifying the Camel version we want to run: Note Camel JBang uses a default Camel version and if you want you can use -Dcamel.jbang.version option to explicitly set a Camel version overwriting the default. The step is to run it in a Kubernetes cluster where Camel K is installed. Let us use the Camel K plugin for Camel JBang here instead of kamel CLI. This way, you can use the same JBang tooling to both run the Camel K integration locally and on the K8s cluster with the operator. The JBang plugin documentation can be found here: Camel JBang Kubernetes . You see that the Camel K operator takes care to do the necessary transformation and build the Integration and related resources according to the expected lifecycle. Once this is live, you can follow up with the operations you usually do on a deployed Integration. The benefit of this process is that you need not worry about the remote cluster until you are satisfied with your Integration tuned locally. 1.1.3. Fine tuning for Cloud Once your Integration ready, you must take care about the kind of tuning, related to cluster deployment. Having this, you need not worry on deployment details at an early stage of the development. Or you can even have a separation of roles in your company where the domain expert may develop the integration locally and the cluster expert may do the deployment at a later stage. Let us see an example about how to develop an integration that will later need some fine tuning in the cluster. import org.apache.camel.builder.RouteBuilder; public class MyJBangRoute extends RouteBuilder { @Override public void configure() throws Exception { from("file:/tmp/input") .convertBodyTo(String.class) .log("Processing file USD{headers.CamelFileName} with content: USD{body}") /* .filter(simple("USD{body} !contains 'checked'")) .log("WARN not checked: USD{body}") .to("file:/tmp/discarded") .end() .to("file:/tmp/output"); */ .choice() .when(simple("USD{body} !contains 'checked'")) .log("WARN not checked!") .to("file:/tmp/discarded") .otherwise() .to("file:/tmp/output") .end(); } } There is a process that is in charge to write files into a directory. You must filter those files based on their content. We have left the code comments on purpose because it was the way we developed iteratively. We tested something locally with Camel JBang, until we came to the final version of the integration. We had tested the Filter EIP but while testing we needed a Content Based Router EIP instead. It must sound a familiar process as it happens probably every time we develop something. Now that we are ready, we run a last round of testing locally via Camel JBang: We have tested adding files on the input directory. Ready to promote to my development cluster! Use the Camel K JBang plugin here to run the integration on K8s so you do not need to switch tooling. Run the following command: The Integration started correctly, but we are using a file system that is local to the Pod where the Integration is running. 1.1.3.1. Kubernetes fine tuning Now, let us configure our application for the cloud. Cloud Native development must take into consideration a series of challenges that are implicit in the way how this new paradigm works (as a reference see the 12 factors ). Kubernetes can be sometimes a bit difficult to fine tune. Many resources to edit and check. Camel K provide a user friendly way to apply most of the tuning your application needs directly in the kamel run command (or in the modeline ). You must get familiar with Camel K Traits . In this case we want to use certain volumes we had availed in our cluster. We can use the --volume option (syntactic sugar of mount trait ) and enable them easily. We can read and write on those volumes from some other Pod : it depends on the architecture of our Integration process. You must iterate this tuning as well, but at least, now that the internals of the route have been polished locally you must focus on deployment aspects only. And, once you are ready with this, take the benefit of kamel promote to move your Integration through various stages of development . 1.1.4. How to test Kamelet locally? Another benefit of Camel JBang is the ability to test a Kamelet locally. Until now, the easiest possibility to test a Kamelet was to upload to a Kubernetes cluster and to run some Integration using it via Camel K. Let us develop a simple Kamelet for this scope. It is a Coffee source we are using to generate random coffee events. apiVersion: camel.apache.org/v1 kind: Kamelet metadata: name: coffee-source annotations: camel.apache.org/kamelet.support.level: "Stable" camel.apache.org/catalog.version: "4.7.0-SNAPSHOT" camel.apache.org/kamelet.icon: "data:image/svg+xml;base64,<?xml version="1.0" encoding="UTF-8" standalone="no"?>
