docker-qemu-arm

Run Docker x86_64 on Android Tablets or Phones

Original idea: https://gist.github.com/oofnikj/e79aef095cd08756f7f26ed244355d62

This is a automatic installation script. As RAM is always an issue on a cell phone, we also install zram.

Known Issues / Hacks / Warnings

• Termux easily gets outdated very quickly! Sometimes packages dependencies or mirrors are broken.
• If you don't have the skills to properly fix this you might want to backup your data, uninstall and reinstall Termux.
• Alpine Linux & dns & ipv4 only vs ipv4/6 is (very often) broken.
• Mitigation: the script turns off ipv6 and set the dns to 8.8.8.8 (can be changed).
