[lburgazzoli]

Can you add some more information about the environment ?

[waytoharish]

I am using minishift on Laptop OCv3.11.Please let me know if you need any specific information

[lburgazzoli]

would be nice to know the camel-k version, knative version, the command line used to run the code and how the camel-k operator is configured (i.e. provide the IntegrationPlatform custom resource)

[waytoharish]

I am running this on minishift 3.11. CamelK operator installed using "Kamel Install". Below is other details.

bash-3.2$ Kamel version
Camel K Client 1.0.0-RC1

Operator Imaged Used --
docker.io/apache/camel-k:1.0.0-RC1

Command used to run the code--
kamel run --name=withrest --dependency=camel-undertow examples/routes.js --dev

attached is the route.js
routes.txt

Please let me know if anything else required.

This issue i am facing with all the CamelK resource creation.

[lburgazzoli]

What is the knative version you have installed ? camel-k now requires serving v1 api

[waytoharish]

I have not manually installed Knative. I have followed the CamelK document and there is no Knative install step.

[lburgazzoli]

can you post the output of:

1. oc get integrationplatform -o yaml
2. oc get integration withrest -o yaml

[lburgazzoli]

looks like camel-k thinks you have knative installed somehow. can you try to delete the integration kits and run it again ?

oc delete integrationkits --all
oc delete integrations --all

I'm trying to install minishift but experiencing few issues to get it running

[lburgazzoli]

I did try to reproduce the issue but it works for me so to me it looks like your minishift set-up is somehow broken, can you try to recreate it ?

[waytoharish]

So just to let you know i do have Knative installed and running for other OpenShift NameSpace not the one i am running using Camel and if this is the case then this is BIg issue in my view.What do you think we can not have 2 different NameSpaces one belong to Knative and one for CamelK on minishift ??

[oscerd]

Is there a specific reason you can't have knative on the same namespace?

[lburgazzoli]

in that case you have different options:

• install a knative version compatible with camel-k 1.0.0-RC1
• disable knative injection in your namespace
• configure the IntegrationPlatform to use the OpenShift profile by default i.e. upon installation you can use the flag --trait-profile OpenShift
• run the integration with a specific profile with --profile OpenShift

[waytoharish]

Please could you help me how to do the same since i am using minishift. Like this a common scenario and everybody can stuck with

[lburgazzoli]

the simplest thing you can do is:

kamel run --name=withrest --dependency=camel-undertow examples/routes.js --dev --profile OpenShift

this will instruct camel-k to deploy applications without taking into account knative

[waytoharish]

Thanks. Let me try to test this and will update you

[waytoharish]

Got it working now. Thanks
