Multi-arch build, what about Travis?

Following the previous article where we saw how to build multi arch images using GitHub Actions, we will now show how to do the same thing using another CI. In this article, we’ll consider Travis, which is one of the most tricky ones to use for this use case.

You may notice that we specified using “bionic” to have the latest version of Ubuntu available – Ubuntu 18.04 (Bionic Beaver).

Once you have run this, you can see that we now have the version 19.03 of the Docker Engine.

So, if we add that line to our configuration file and run it again, this will allow buildx to have an instance of a buildkit running to build the multiarch images.
