[GitHub] [camel-k] chander35 opened a new issue, #4256: unable to access the URL and unable to expose port after the integration build is successfully deployed.
chander35 opened a new issue, #4256:
URL: https://github.com/apache/camel-k/issues/4256
Here, I have used a simple code to expose the REST url as i mentioned below
<img width="458" alt="image" src="https://user-images.githubusercontent.com/128601152/231826248-9ac7a69c-ab5b-46e8-9ced-1184e8d8487d.png">
when I run the Kamel command for the same REST code, the build got successful and shown message like **"Listening on: http://0.0.0.0:8080"**, below I have shared the screenshot for the same.

But Iam not able to access the url as mentioned above, I have tried different ways to access like
**http://0.0.0.0:8080/hello
http://localhost:8080/hello
http://127.0.0.1:8080/hello** in web browser as well as in postman, still no use.
later I got to know that we need to expose the port in docker to access the actual 8080 port, so i tried below mentioned command to expose outside the docker **"docker run -it -p 8080:8080 <image name> "** but every time iam getting same error as shown below
<img width="844" alt="image" src="https://user-images.githubusercontent.com/128601152/231830209-bcf08f04-e362-4f4e-a5e3-606a11209fa8.png">
I want to know where i am doing wrong and how can i resolve this.

If your goal is to access your rest end point from outside the K8s cluster, you will need to add an ingress https://kubernetes.io/docs/concepts/services-networking/ingress/

Thank you @essobedo, It started working with your command, I have tried many ways to expose the port but none of them are worked, thank you for your dedication to resolve my issue and now I am able to expose the port and able to access it, Thank you so much.

I have a question, do we need to run "**kubectl port-forward svc/rest-dsl 8080:80 -n <your-namespace-here>**" command every time when ever we want to expose the above "RestDSL" class? is there any other way to expose while using the "kamel run "command itself.?
the issue with this is, if the code has changed then the port-forwarder is stopping immediately, so need to start again every time to access the url.

What you are looking for is port forwarding https://kubernetes.io/docs/tasks/access-application-cluster/port-forward-access-application-cluster/
Camel-K should have created a service automatically for you.
You can check it with the next command:
```
kubectl get svc -n <your-namespace-here>
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
rest-dsl ClusterIP 10.96.195.112 <none> 80/TCP 82s
```
In the previous example, the service `rest-dsl` is listening on port `80` so assuming that you would like to access your application from port `8080` on your local machine, the corresponding `port-forward` command is then:
```
kubectl port-forward svc/rest-dsl 8080:80 -n <your-namespace-here>
```
The code of the integration that I used:
```
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.Exchange;
public class RestDSL extends RouteBuilder {
@Override
public void configure() throws Exception {
rest()
.get("/hello")
.to("direct:hello");
from("direct:hello")
.setHeader(Exchange.CONTENT_TYPE, constant("text/plain"))
.transform().simple("Hello, Camel K");
}
}
```

Well, this is required if you're on a local cluster such as Minikube or the like. With the port-forward, you'll be able to "see" the Kubernetes service which otherwise is not available. In a real environment, you should be able to access the service OOTB.

Just to avoid misunderstanding, if your goal is to access your service from localhost, `port-forward` will always be needed whatever the cluster used behind (local or not)
