@svor Maybe better to set as an env variable? so it works also when you start from the terminal?
QUARKUS_HTTP_HOST

do we have the same issue with the native app ?

[svor]

@sunix As I see we don't have this issue with the native app:

You can try it https://che.openshift.io/factory?url=https://raw.githubusercontent.com/svor/che-devfile-registry/sv/quarkusFix/devfiles/quarkus/devfile.yaml

[sunix]

Still, I think it is better to set that as an environment variable in the container.
At the moment some users won't notice that there are predefined tasks. These one would just start the terminal and run ./mvnw compile quarkus:dev and it won't work as expected.

QUARKUS_HTTP_HOST

@sunix If we have this value in env variable, we will get a problem with tests:

I don't have your error
maybe you are passing -Dquarkus.http.host=0.0.0.0 and not 0.0.0.0 in your QUARKUS_HTTP_HOST env variable
