Right now I want to download JDK 17 on mybinder.org however i try many solutions but cant download JDK can you help me
Without knowing what you’re trying to get done with some java, I’d recommend trying to get started as simply as possible. There are some more options packages that have more/fewer dependencies, but unless you really need all the GUI stuff, this is a fine place to start.
Because the JDK is a relatively “heavyweight” dependency, it needs to be installed with apt. Create a file called apt.txt (or binder/apt.txt (or .binder/apt.txt)) with the content:
ca-certificates-java
openjdk-17-jre-headless
I observed that the certificates package needed to be explicitly listed, though I don’t think order matters.
Good luck!

you need to create that file in your repo before binder builds it:
https://mybinder.readthedocs.io/en/latest/config_files.html#apt-txt-install-packages-with-apt-get
then, once it starts, you should be able to run “java”… we still don’t know what you are trying to do, so it is hard to help further.

Do you have social media
Can I add friend to get help from you
Here’s a gist including a binder link that shows the above approach. I can’t make myself any more available/clear than what you’re seeing right now.

I’ve only been learning programming for 2 years, so there are many things I don’t know, thank you very much for helping me
Can you record a video of how you apply apt.txt to mybinder and upload it to youtube?
I want to open the port for them, is there a way?
apply apt.txt to mybinder
a quick starting point would be to fork the previously-linked gist, and then add your stuff, but basically:
- make a repo (on e.g. gist or github or gitlab)
- make a file called apt.txt with the packages listed in it
- start a binder pointed at that repo
a look at the steps on the previously-linked repo2docker docs (whoops, they moved to Configuration Files — Binder 0.1b documentation) should lay out all of even more options.
while it will be somewhat slow, iterating on your binder and getting comfortable with the files available will help you find out what you need to know. If it’s open source, you could share it here, and get more focused feedback: but aside from “jdk 17” and “open some ports” we’re still pretty much in the dark of what you’re trying to accomplish… and whether binder is even a good match for it.
open the port for them
unlikely: on mybinder, you get one port. you might be able to add jupyter-server-proxy to a requirements.txt or environment.yml to proxy expose additional ports behind it, but, by design, you can’t run full “server” applications (to serve many clients) on binder.
