mybinder.org now supports julia 1.x, including Project.toml and Manifest.toml files, out of the box. How do you use it? You create a github repo, put a Project.toml and Manifest.toml in the root and add some Jupyter Notebooks to the repo. Then you go to https://mybinder.org/ and enter the URL of yo…

Yes, but sometimes it is also super fast. I think there is some caching of docker images going on, including with all packages installed. So if you are lucky and the cached image is still around, you might not have to wait at all. At least that is what I think is going on, I’m actually not sure, tho…

As I wrote here , I think that it takes an awfully long time to create the Docker image and install all the packages. This happens basically after every commit to the repository. Once the image is done, it’s cached and will be immediately ready to use. As I suggested in the linked post, show the l…

[image] xiaodai: It will automatically spin up a VM instance in the cloud (I believe Google hosted), provision it with exactly the julia environment that is specified in the Project.toml and Manifest.toml , It can take a “long” time to spin up such an environment because the installations of …

Thanks for clarifying this, @betatim ! I should add that @betatim was the Jupyter Binder team member who shepherded and helped us with all of this, thanks again :slight_smile:

Thanks to you and @NHDaly for taking the time to be our Julia experts! We need the contributions from people who use a particular language every day to help get things right and make them feel “Julia-stic” (Is there a Julia equivalent to Pythonic?)

I think I’m actually most excited about the potential to at some point use PackageCompiler.jl to create a custom sysimage with mybinder.org , see this issue. If we can pull that off, the whole compiled sysimage (that includes the packages that are added to Package.toml) would be cached in the docker…

[image] davidanthoff: If we can pull that off It’s bound to happen at some point. I love using it to compile Plots and GR and DataFrames. Actually I maintain a DataBundle of packages where I save the sys.dll.

Would it make sense to search for Project.toml from the notebook directory and up towards the root and use the first one you encounter? Having the project file in the root would then still work, but it makes it possible to have some more fine grained control.

It might well make sense to change this line so that JULIA_PROJECT=@., I’m just not sure, so any further thoughts on that would be great. I do think that if we go towards a model where we try to use PackageCompiler.jl by default on mybinder, then it would be easier if there was just the one project…
