Termux-packages: Udocker installs in Termux!

[SDRausty]

Udocker is a "basic user tool to execute simple docker containers in user space without requiring root privileges". This "Enables download and execution of docker containers by non-privileged users in Linux systems where docker is unavailable".

The result is similar, but not identical with Arch Linux in Termux PRoot:

udocker.py doesn't seem to accept a "install" argument.
Try installing it as other python projects, with python setup.py install.

[SDRausty]

@Grimler91 Thank you. Installs, but does not work as expected in Termux and Termux PRoot. Any idea why?

Try with python2 perhaps. Seems like a rather trivial error in udocker.
Your upstream issue hopefully get some attention so that it is fixed.

[SDRausty]

The result is much better with Python 2:

        Udocker installation instructions are available at:

          https://indigo-dc.gitbooks.io/udocker/content/

        Udocker requires additional tools to run. These are available
        in the tarball that comprises udocker. The tarballs are available
        at the INDIGO-DataCloud repository under tarballs at:

Thank you for the thorough instructions in this issue @Grimler91.

Udocker appears to suffer from the same affliction as gradle, and some others do too: exclusive x86 dependency; Do you agree?

[SDRausty]

The result is much better with Python 2:

python2 setup.py install

It is Python 2 only:

[estebond]

@sdrausty Were you able to successfully run the command above and install the udocker tools?

[davemackintosh]

It does sort of install but there are no available tarballs for ARM and thus it doesn't fully install.

[SDRausty]

thus it doesn't fully install

@davemackintosh it does now. It is udocker btw:

udocker is a basic user tool to execute simple docker containers in user space without requiring root privileges

The commands pacman -S python2-pip && pip2 install setuptools have got udocker running on Android 10 in Arch Linux in Termux PRoot:

Do you know the next command and a good simple primer about docker?

[davemackintosh]

I gave up on this a long time ago. I use ngrok to tunnel a sub domain of my site to a latte panda in my office and just use docker-compose. If you want to learn about Docker check YouTube and the documentation.

[SDRausty]

Were you able to successfully run the command above and install the udocker tools?

@estebond yes, the commands finally ran successfully. How do you install the udocker tools?
