Ask quick dev questions about mybinder.org, BinderHub, and repo2docker. Use discourse.jupyter.org for user questions, support, and discussion.
Yes. The other problem there is GKE is our prime cluster and houses our redirection logic. So if it goes down, there isn't a way to get to the other clusters without knowing their URL :confused: We have been having discussions in the team about improving the sustainability of our services
Another good option for important tutorials: follow https://zero-to-jupyterhub.readthedocs.io/en/latest/. I've done this on AWS and Azure for years and it works great. Don't have to know much about these systems to successfully follow the instructions.
Hi,
I am having an issue with git-lfs and repo2docker . I added a git-lfs pull command in the post-build command of my repo.
When executed on binder, the git-lfs pull works 🎉. However, when I execute it locally via repo2docker, I get an error :
batch request: Warning: Permanently added the ECDSA host key for IP address '140.82.121.4' to the list of known hosts.
git@github.com: Permission denied (publickey).: exit status 255
error: failed to fetch some objects from 'https://github.com/adrienpacifico/python_data_science.git/info/lfs'Does someone know why?

Hi! I'm trying to revive a github repository i used on mybinder, it worked last year, but not this year. It now says: "unauthorized: authentication required" after pushing image. What should I add to make it work? Thanks! running from https://mybinder.org/ basically following http://mybinder.org/v2/gh/binder-examples/r/master?urlpath=rstudio example.
The state i tried is here: https://github.com/peeter-t2/TM-TartuSpring2022/tree/b086b7498cf4c3737292aaba5da559aa3e68422a. But when I reran it this morning it no longer had that problem. Yesterday it failed to open 3-4 times. Now removed jupytext in the last commit which made the startup faster.
No idea what was going on, but problem solved for now. If you've any idea what was going on, I'm still interested. But thanks in either case!

Hi all, I've been monitoring https://mybinder.readthedocs.io/en/latest/about/status.html for a while recently. Out of curiosity, the total quota of mybinder.org federation is 400(gke 200, ovh 80, gesis 120), does that mean the maximum concurrent users is 400? Am I right about it? Even if GKE goes down, we can still use ovh.mybinder.org or gesis.mybinder.org, but the maximum concurrent users will be 80 and 120 respectively, is that right?
It seems that the latest release of repo2docker fails on any R environment.
Although master works.
Are there specific plans for the next release of repo2docker to fix this?
to my knowledge it hasn't been discussed though
Anyone knows what's going on here, how can I fix it?
I think you're running into this: https://stackoverflow.com/questions/63066604/error-kubernetes-cluster-unreachable-get-http-localhost8080-versiontimeou
for example to start
jupyter nbclassic or jupyter lab directly, without using jupyter-server-proxy
this gist used to work about a year ago: https://gist.github.com/jtpio/fca78a722eee2ca968acf38c629c277c
using the following in the
start script: exec jupyter nbclassic --ip 0.0.0.0 "${@:3}"
and while the Binder image builds fine, the server doesn't start anymore
2022-04-25T12:00:31Z [Normal] Started container notebook
Spawn failed: Server at http://10.0.10.47:8888/user/jtpio-4e9a3d435-c4150c10abbb1d7-g4vsup0y/ didn't respond in 30 seconds
Launch attempt 2 failed, retrying...

looks like there might be some relevant changes to
repo2docker-entrypoint based on the git history: https://github.com/jupyterhub/repo2docker/commits/main/repo2docker/buildpacks/repo2docker-entrypoint

using the following in the
startscript:exec jupyter nbclassic --ip 0.0.0.0 "${@:3}"
OK so after trying a couple of different combinations, the following command seems to be working on Binder: exec jupyter nbclassic "${@:4}"
while locally with jupyter-repo2docker it should be exec jupyter nbclassic "${@:3}" (the difference is the 3)
not sure exactly where, but probably Binder passes an extra argument when starting the container
maybe we should document this somewhere in an issue, or document how folks can spawn their custom UI using this kind of example
Here's a question, though: why are you stripping more than one item? Shouldn't it just be replacing the executable?
The format of the command on BinderHub is
python3 -c "some startup code" [extra args for server app]
Overriding the start command is fundamentally incompatible with passing anything important via positional args. This is why JupyterHub has stopped using positional args, entirely. We should try to do the same with Binder, but that's harder because we don't control the default executable (notebook), so we can't easily add environment support for every option.
The best heuristic I can think of right now, is to find the first CLI arg that starts with
-- and slice there.
absolutely not robust, but more likely to work more often
Hi If I use "pip install git+https://github.com/jupyterhub/binderhub
" on my machine, does it means I can access bindehub from the brower?

Generally the BinderHub python package isn't pip installed, it is controlled by a helm chart which is deployed onto a Kubernetes cluster and that is what gives you browser access
pip installing it, might work for local repos
Hi everyone! Has anyone ever tried to set up a BinderHub deployment using Artifactory as the Docker registry? The docs seem to suggest using a using a custom registry is possible, but nothing online seems to suggest Artifactory has been tried before. Any insights?
