You can obtain the updated .travis.yml from my GitHub:
https://github.com/hmenke/texlive-source/blob/master/.travis.yml

It contains the following builds:
Native Travis (a.k.a. Ubuntu 14.04 amd64)
Debian amd64
Debian i386
Alpine x86_64
Alpine x86

The Debian and Alpine builds run via Docker and generate a tar.gz archive which contains the "inst"
directory.  The Alpine x86 build does not work though and hangs indefinitely which I can also
reproduce locally.
https://travis-ci.org/hmenke/texlive-source/jobs/333045568
It's up to you whether you want to kick it out.  I don't need the x86 binaries but I'd guess it's a
smoking gun of something needing to be fixed.


Now how do you get those binaries to GitHub releases?

1. You need an account with push access to TeX-Live/texlive-source.  With this account navigate to h
ttps://github.com/settings/tokens and generate a new token with scope "public_repo".  I usually give
my tokens some mnemonic names like "Travis CI texlive-source".
2. Copy the token and go to https://travis-ci.org/TeX-Live/texlive-source/settings.  In the section
environment variables paste the token with the name "GH_TOKEN".  Make sure that "Display value in
build log" is set to off and click add.
3. You're all set.  Go to https://github.com/TeX-Live/texlive-source/releases and click "Create new
release".

As an example I created a release with the title "Just a test" and the tag "bogus" on my GitHub
https://github.com/hmenke/texlive-source/releases
