Are there any known errors to running jupyter lab build with a custom dockerfile? It builds locally with jupyter-repo2docker. Here is the error we get, in this case the @jupyterlab/server-proxy extension:

maybe it exceeds the memory limit?

i'd run repo2docker locally with 2GB as limit to see what happens

HI all, having a binderhub --> jupyterhub communications issue. I've got jupyterhub running on one k8s cluster on one domain, and binderhub running on a different cluster on a different domain, so a little non-standard. Binderhub works fine, until it tries to create a temporary user on jupyterhub. I get errors like

[W 2020-09-14 19:54:43.245 JupyterHub log:174] 403 POST /hub/api/users/binder-examples-requirements-a3bknnqf (binder@172.17.0.1) 5.98ms

. I figure this is a problem with the API token. I looked in the pods and on binderhub /etc/binderhub/secret/binder.hub-token is identical to hub.services.binder.apiTokenin /etc/jupyterhub/secret/values.yaml. Is there anything else I can check to figure out why I'm getting these 403s?

(The error on the binder side isFailed to create temporary user)

Hi there! I'm interested in using a repo2docker container as part of my CI workflow using github actions. When I try to check out my repo inside the container, I get a permission denied error: https://github.com/cmelab/notebook_tutorials/runs/1114597849?check_suite_focus=true

oops, I'm sorry that's the wrong link https://github.com/cmelab/notebook_tutorials/runs/1104272456?check_suite_focus=true shows permission denied error

Are there any working examples out there of dataverse repos that can be run by binder? I found a couple of old broken ones

Hi all, when I try to get at https://mybinder.org/v2/gh/imagejan/image-processing-courses/update-2019?filepath=03-image-processing-filtering.ipynb I get:

Found built image, launching...
Launching server...
Internal Server Error

Is that a known problem? That link/repo was working well in the past.

We're currently upgrading the nodes so it could just be a temporary outage https://twitter.com/mybinderteam/status/1305771888057167873

@betatim

thanks for reporting. we will take a look at the logs

Tim Head

@betatim

this is a bug that i thought we had already solved :(

so thanks for reporting it

in the end without the bug it would have told you "launching took to long, let me try again"

the bug is in the handler for "launch took to long"

Jan Eglinger

@imagejan

ah, thanks for looking into it. In the end it worked for me after trying again.

Hello again! I am looking for using Binderhub as a platform for a MOOC instructional experiment. I am curious if Binderhub allows an instructor to put instructional videos to a repository in addition to only ipynb files?

Let's say I have 3 instructional videos which teach the content stored at 3 ipynb files, could I put only the 3 ipynb files, but also the 3 videos to a repository, and then set up a Binderhub based on that repository?

Fred Mitchell

@fm75

You can use a player for YouTube in a notebook. That way your video is not stored in GitHub.

@choldgraf I'm building jupyter book in binder (because I'm wild) but when I try to open the index.html file I get a 403 error. Any ideas what's up?

Fred Mitchell

@fm75

Doesn't everyone?!

Trying to open it from within Jupyter Lab in binder?

Sarah Gibson

@sgibson91

No, classic interface

Fred Mitchell

@fm75

I use make build and make publish in binder. Then just go to the gh_pages link in a different tab.

Use lab to get the Terminal window. But you could !make in a cell.

Sarah Gibson

@sgibson91

We have !jupyter-book build . in a cell. We're not at the point in the tutorial of where we want to publish

We're just trying to use binder to avoid the hassle of setting everybody up locally

We're going to cover GitHub Actions to publish

we don't have a Makefile for the book yet

(and probably won't)

You can do New > Terminal in the classic interface to get a terminal

Running the command isn't the problem, it's viewing the book

Fred Mitchell

@fm75

Ah. Ok. I tried the same thing. If the file were local you could open in browser. But it is in the container and your browser isn't. Maybe lab has an extension to view HTML? I kind of punted. Pushed changes back to remote and built there. Then I figured out how to add gh-pages into repo. That was really easy. I am doing it in GHE not public GitHub. No actions in our version.

I suspect you need a browser interacting with a "server" to render your page. Does HTML in a code cell work?

Sarah Gibson

@sgibson91

Possibly, we'll try that next. Thanks

We're writing a tutorial for JupyterCon on how to host a Jupyter Book

Hence why we're not keen to have to support people building locally :sweat_smile:

Fred Mitchell

@fm75

Nice!

An awesome combination!

Will that be one of the tutorials before the conference or in the conference itself? I will plan on attending.

Sarah Gibson

@sgibson91

It's one of the 3 hr ones, not a sprint. So I think during the conference?

Fred Mitchell

@fm75

Sad that it is remote this year.

Sarah Gibson

@sgibson91

(It's embarrassing that I know so little as a track co-chair)

Yeah, I was looking forward to a hackathon with the Binder team

Fred Mitchell

@fm75

Oct 5-9 Tutorials. 12-16 Conference. 17 Sprints

I have not seen any sort of list of tutorials yet.

Sarah Gibson

@sgibson91

I don't think the schedule has been officially announced yet

Chris Holdgraf

@choldgraf

@sgibson91 hey, just seeing this now...if you've got an issue where you're coordinating this tutorial maybe we can chat there? It is hard for me to keep track of conversations in gitter since I am AFK much of the time due to 👶

Sarah Gibson

@sgibson91

No problem, I'll create one and tag you. Thanks!
