Note: As of the day of writing this, the latest version of the docker package is broken on Termux. This part of the blog series demonstrates how to build an older working version of docker. If the latest version of docker works, please skip this part.

In case you require to build an older version of docker, the following steps may be helpful.

1. Follow the instructions here to setup the package building environment on your Host OS preferably.

2. Checkout the relevant version of the termux-packages repo.

   git checkout 64e0fe
   

3. Build the docker package!

   ./build-package.sh -I docker
   

4. Note: since this is an outdated version, some source tarball URLs may be invalid. Replace them with other source URLs, or if you want to replace them with source tarballs for newer versions, ensure that the sha256sum is also changed.

5. After the packages are built on the Host OS, use adb push to push them to your phone, where they can then be installed from inside Termux.
