Processes listening on localhost are not exposed by the gateway

[l0rd]

Describe the bug

Although I have defined the following endpoint in my devfile:

      - name: tilt
        targetPort: 10350
        exposure: public
        protocol: http
        attributes:
          urlRewriteSupported: false

Eclipe Che Port extension ask me if I want to add a redirect to it:

And although I answer yes to this question then I am not able to access the application using the browser. I get a blank screen:

If I start the application to listen to the interface 0.0.0.0 then everything works fine:

Che version

next (development version)

Steps to reproduce

Open a workspace Eclipse Che dogfooding using this link (for Che committers only) instance.

Open a shell and run tilt up:

cd 201-quarkus-live-update && tilt up -f Tiltfile.buildah

Expected behavior

I was expecting the port to be redirected automatically (without asking).

And in particular I need to set the attribute urlRewriteSupported: false on that endpoint and that's not the case with the pre-defined che-code endpoints.

@benoitf do you have any clue?

[benoitf]

@l0rd my guess it that tilt is listening to 127.0.0.1 only so while you're saying that this port is reachable from the outside it's still not 'exposed'

try using --host 0.0.0.0 on tilt

tilt up --host 0.0.0.0 -f Tiltfile.buildah

@benoitf Changing the command to listen to interface 0.0.0.0 works fine 👍

[benoitf]

should we close the issue then ?

[l0rd]

I have updated the description but it still looks like a gateway issue (not a plugin-port issue). We should be able to expose processes listening to localhost too shouldn't we?

[benoitf]

yes it should be the role of the gateway to simplify such usecase (do not need to change commands to execute)
