Double app icon

Hi There,

I’m experiencing an issue with a double definition of my interactive app, one for “manifest.yml” and “form.yml.” This problem initially occurred when I first installed Ondemand three weeks ago, but it mysteriously disappeared at some point. However, it has resurfaced after I reinstalled my node and the Ondemand suite.

I’ve been using symlinks to point to “/etc/ood/config/apps” because I prefer not to directly edit files in “/var/www/ood.” However, even after migrating into /var/www/ood/apps/sys the double definition issue persists.

Here the content of my files:

$ egrep -v "^.*#" manifest.yml form.yml 
manifest.yml:name: JupyterLab
manifest.yml:category: Interactive Apps
manifest.yml:subcategory: Servers
manifest.yml:role: batch_connect

Thank your for your help,

What version of OOD are you on and what OS?

There would have to be a duplicate on the file system somhow for this to happen. I haven’t been able to replicate anything without having some other directory with the same manifest and form. Now, it is entirely possible to name this directory something else and have it show up, such as bc_osc_jupyter_backup.

Is there anyway you have a backup somewhere or duplication?

OOD:   ondemand-3.0.3-1.el8.x86_64
OS :   Rocky8 4.18.0-477.10.1.el8_8.x86_64

That’s weird, for example if I delete the symlink of JupyterLab, then I do not have access to any JupyterLab App. That’s mean I haven’t duplicate “form/manifest” for jupyterLab¨. And I check everywhere I have only these 3 directory (JupyterLab, VSCode-server and MatLab).

But the thing I do not understand is “JupyterLab: form” and “JupyterLab: manifest” apps. Ondemand app seems to see the difference beetween theses those files.

Here the content of my directorie

$ find /etc/ood/config/apps -iname form.yml*

$ ll JupyterLab/

Sorry, looking at this closer now. Initially I read this and was just focused on the duplication, but it is strange to see these form and manifest options, that shouldn’t be happening.

But, looking at the manifest has me curious. It looks like you never set the fields for the app. I wonder if OOD does a best effort there somehow to retrieve these if they aren’t defined and this is what we are seeing.

If you open your manifest.yml and do something like this:

name: Jupyter 
category: Interactive Apps
subcategory: Servers
role: batch_connect
description: |
  This app will launch a JupyterLab on one node

what happens on reload?

Hi @travert,

Thanks for your suggestion, I’ll give it a try.

But I think I’ve found the problem, the name of the symbolic link and the target directory are the same. If I change the name of the symbolic link, the duplicate disappears.

Sorry but I do not see the difference beetween my file and your suggestion. My eyes are blind x_x

Ha, no you are not blind. I had scrolled down in the raw text window, and the later when I glanced back in the browser my brain forgot and I thought the file was missing contents :face_palm

Great to hear, though I’ve got symlinked directories that share names and don’t see this duplication and I still don’t understand how you have those form and manifest entries for each app.
