User Story

As an odo user, I want to be able to set the ports detected automatically by odo when calling odo init interactively even if the suggested Devfile has many container components So that I can have my Devfile initialized right away with the right ports without having to edit it later on.

#5863 added the ability to automatically detect my application ports from the source code and use that as ports when initializing a Devfile interactively, but odo currently shows a warning if the Devfile has multiple container components:

odo/pkg/init/backend/applicationports.go

Lines 33 to 39 in b481d4c

	if nbContainerComponents > 1 {
	klog.V(3).Infof("found more than 1 container components in Devfile at path %q => cannot find out which component needs to be updated."+
	"This case will be handled in https://github.com/redhat-developer/odo/issues/6264", devfileobj.Ctx.GetAbsPath())
	fmt.Fprintln(w, "\nApplication ports detected but the current Devfile contains multiple container components. Could not determine which component to update. "+
	"Please feel free to customize the Devfile configuration.")
	return devfileobj, nil
	}

As discussed in #6211 (comment), there might be issues with Devfiles that have more than one container components.
#6919 handles the simpler case of a Devfile that has at most one container component, and the goal of this issue is to handle the case where the Devfile has more than one container component when running odo init interactively. #6923 will handle the case for the non-interactive mode.

Acceptance Criteria

• It should ...

Comments

• An idea discussed in odo init interactive mode: Automatic port detection based on Alizer detection #5863 (comment): figure out the container with mountSources (the main container), and override ports for it. But this can have some limitations
• Another idea is to use the run command and determine the container component it uses. This is what will is mentioned for handling the non-interactive mode: odo init non-interactive mode: Allow specifying ports when Devfile has multiple container components #6923
