Zero-to-binder fork (binder-examples) is not building on mybinder

Binder mybinder.org ops

I was trying to find a working example repo that is not cached on mybinder, for that I decided to fork a very basic one:

at

but the fork is not building because of this error:

maybe there’s a simpler example I can try? sorry, I’m totally new to binderhub.

The Turing Way has a tutorial that may help, it is based on the contents of that repo. It might at least unblock you while we try to work out what’s going wrong with the original repo.

Thanks, Sarah,

I was able to bootstrap homemade-ML on mybinderhub, but using binderhub 0.2.0-n472.h32e06ee on our own binderhub deployment we’re getting the error below. Let me know if there a ultra ultra simple hello world repo you can share. We’re excited because we’re able to spin up infrastructure on our own. Right now, we just need to test it, thus the reason for seeking a ‘kiss’ hello world.

Thanks,

G

Just to add extra info. The container built successfully, but launching gives us Internal Server Error in the BH console. The stuff above is from kubectl logs binder. Thanks,

The repo for the apt_install example is simpler, especially if you remove the postBuild from your fork.

I know you are looking for one that fits the criteria of ‘working example repo that is not cached on mybinder’; however, I think you are over-thinking that ‘working example’ part. You can use any plain, extremely basic new repo or repo branch. A binderhub will spin up a minimal Python-backed Jupyter environment and essentially git clone the contents if you don’t have any requirements.txt or environment.yml or other config file. Or at least this is what MyBinder does. So you can always make a new branch or repo and test it on yours first. And then test it on MyBinder later, if you must. If you don’t put ‘anything of substance’ in your repo, it will build via MyBinder. (Once you demonstrate that last statement a few times for yourself, you’ll trust it. I just used this one to test what I was saying. It only has a README.md and a license file.)

I tend to use GitHub - binder-examples/requirements: Simple requirements.txt based example to test my BinderHub deployments. As @fomightez said above, any new branch or minimal repo would be suffice to test on mybinder.

Thanks, @fomightez @sgibson91 I’m using GitHub - binderhub-test-org/test-repo-public: Public repo to test permissions with Hub23, that’s all I needed.

Just for the record, It’s working flawlessly on GKE but for EKS I’ve got this error below. This is weird since I’m using the exact same public docker registry config. Thanks for the help!

Can you share your config, secrets redacted?

thanks, Sarah,

I found a bug in my script, I was not giving the right config file to helm. :man_facepalming: sorry about that.

No worries! Happens to the best of us :slight_smile:
