/var/git/bc_example_jupyter doesn't contain code

[iqlinuxadmin]

It says here:
https://github.com/ubccr/hpc-toolset-tutorial/blob/master/ondemand/README.md#create-the-jupyter-application
to use /var/git/bc_example_jupyter as the Git Remote, but the only thing in that directory is the files that normally live in .git. The actual bc_example_jupyter code is not there. If I use https://github.com/OSC/bc_example_jupyter as the Git Remote, everything works fine. I'm guessing you prefer to use a local directory to avoid some downloading during conferences, but it's not working as is. Here's what's there:

[hpcadmin@ondemand bc_example_jupyter]$ pwd
/var/git/bc_example_jupyter
[hpcadmin@ondemand bc_example_jupyter]$ ls -A
branches  config  description  HEAD  hooks  info  objects  packed-refs  refs

I see there's also an ood_example_ps directory in /var/git. I haven't gotten to the point in the tutorial where I'd be using that, but it looks like it too only has the contents of .git without any actual code.

It appears to be a bare clone

hpc-toolset-tutorial/ondemand/install.sh

Line 87 in 761e76b

git clone https://github.com/OSC/bc_example_jupyter.git --bare /var/git/bc_example_jupyter

But more importantly - does that step not work? I mean when you "create the app" does it not create the app correctly?

[iqlinuxadmin]

Hm. I wonder if something went wrong when I ran install.sh. I'll go back and start the whole tutorial from scratch and see what happens.

[iqlinuxadmin]

Ok. I didn't run install.sh. I may have missed it, but I don't see it referenced in the directions...

[iqlinuxadmin]

What I am doing is starting on this page: https://github.com/ubccr/hpc-toolset-tutorial/blob/master/README.md and following the links to the next pages, running everything I see. For coldfront, I did the "Start From Scratch" version of the instructions, though I wouldn't expect that to affect OOD.

I'm doing this to self train, but I figured I might as well clarify or update anything I found as I went through it.

When the containers are being built, they run this shell script as a part of the build process.

Are you not working off of the containers provided in this repo?

[iqlinuxadmin]

I am indeed working off of the containers provided in this repo. It turns out that git clone --bare does exactly the opposite of what you want it to: https://graphite.dev/guides/git-clone-bare-mirror

[iqlinuxadmin]

This would work:

git clone --depth 1 https://github.com/OSC/bc_example_jupyter.git /var/git/bc_example_jupyter && rm -rf /var/git/bc_example_jupyter/.git

[iqlinuxadmin]

Okay, I made a PR for this.

[johrstrom]

Okay, I made a PR for this.

I'll have to boot these containers up to see what happens, but I'm pretty sure when you make the application from this path it does in fact copy all the files.

A glance at the code indicates it does a lot of git operations to make this happen.

https://github.com/OSC/ondemand/blob/01a1fb9dae08df8b54790bca280ec45f871a83ee/apps/dashboard/app/models/product.rb

I guess what I'm asking is - what's the end result when you make an app from this location /var? And is that end result somehow erroneous? From what I recall, it's not erroneous. That is, the end result is that you end up with the actual files that you need in your HOME.

[iqlinuxadmin]

The end result is that it doesn't create the app. I'll try again and give you more details. It seems hard to believe that it doesn't work to me too, since I know this tutorial has been used many times. It makes me think it's something I'm {,not} doing, but I don't know what.

[iqlinuxadmin]

Okay. I started over from scratch. It almost worked. It gave me a permissions error. Once I did `chown hpcadmin:hpcadmin /var/git/bc_example_jupyter' the application was created successfully. I'm going to delete and recreate absolutely everything and see what happens, but not today! If the chown isn't necessary, I'll close this.
