How to access Apache karavan UI when using Minikube

[amit88265]

Hi,
I am exploring camel-karavan to be used a intgeration tool. I trying to run camel Karavan on Minikube by following this guide minikube.md After running every command successfully, am not able to access karavan UI to create Routes. The last command. "minikube service karavan --url --namespace karavan" to access karavan instance not working. Hitting URL from this command does not loading anything from browser. Output from this command is :
http://127.0.0.1:50820
❗ Because you are using a Docker driver on darwin, the terminal needs to be open to run it.

Please help me out. Thanks

I just tried the steps and I am able to see the Karavan Screen. Few things you can try

• Make sure you set the current namespace as karavan kubectl config set-context --current --namespace=karavan
• Modify minikube/karavan-secret.yaml with the correct git values and registry IP. After making these changes you should run kubectl apply -f minikube/karavan-secret.yaml -n karavan
• Make sure that after running command minikube service karavan --url --namespace karavan you copy the URL that looks like http://127.0.0.1:50820/ and paste it into the browser.
• Give it 20-30 seconds to load after the first run.

Thanks for quick reply.
A few doubts I have:

• What is purpose of Gitea repo? Do I need to install provide that details in secret.
• when to execute this command kubectl config set-context --current --namespace=karavan
• There is a field image-registry in secret what is its value? is it minikube ip address or ip adress from command kubectl -n kube-system get svc registry -o jsonpath='{.spec.clusterIP}'

[mrinalsharma]

you can run kubectl config set-context --current --namespace=karavan after creating the namespace. image-registry value is output of the command kubectl -n kube-system get svc registry -o jsonpath='{.spec.clusterIP}'

Karavan keeps the Project in Git repository. you will have to create a git repo and update minikube/karavan-secret.yaml with the Git details.

Created a bitbucket repo and added details in secret.yml. Also followed other steps as you mentioned. But k8s object minikube/karavan.yml is failing with following error.

I am running minikube on Mac M1 (Ventura).

This is the fastest and simplest way to install Karavan on minikube https://github.com/apache/camel-karavan/blob/e507cb5ac45563d3eace11b98aebc27aa8166af0/karavan-cloud/karavan-cli/CLI.md
