Minikube Service pod error

[we-wake-act21]

Hi,

I'm currently attempting to deploy theia-cloud minikube on a Ubuntu - WSL instance on my local machine. The deployment of theia-cloud is successful, and I can access the Keycloak login page. However, upon login, I encounter an error with code 500.

Upon reviewing the logs from the service pod, I noticed the following:

2024-03-04 08:37:15,326 WARN [io.qua.oid.run.OidcRecorder] (vert.x-eventloop-thread-10) OIDC server is not available at the 'https://127.0.0.1.nip.io/keycloak/realms/TheiaCloud' URL. Please make sure it is correct. Note it has to end with a realm value if you work with Keycloak, for example: 'https://localhost:8180/auth/realms/quarkus'

I've added 127.0.0.1.nip.io to the /etc/hosts file with the IP mapping to minikube ip. I'm attempting to access 127.0.0.1.nip.io from my Windows machine.

Is this error associated with deployment or configurations for theia-cloud?

[jfaltermeier]

Hi, if I understand your setup you are running Minikube with Theia Cloud on an Ubuntu machine and are trying to expose this in your network, so you can access this on a windows machine in the same network?
We had a similar question here: #232 (comment)

Regarding the error above: https://127.0.0.1.nip.io/keycloak/realms/TheiaCloud looks for the keycloak on localhost (and this is probably local to the running docker containers then). This should be ${minikube ip}/keycloak/realms/TheiaCloud instead.

Hi,
I resolved this issue by updating the coreDNS configmap to resolve 127.0.0.1.nip.io to $(minikube ip).

Is this a good approach?
