What travis does not have is build chains in the sense of multiple jobs by
different yaml files, but as Martin says the rest is there. What they have
is different steps inside one yaml file (setup, pre_script, post_script,
deployment, ...)
which can be triggered according to branches and tags.

In Kubevirt we also use a .travis.yaml which does testing and releasing
based on tags and branches [1].

Note that for more finetuned controls, they also provide a lot of
environment variables which you can reference (e.g. branch, tag, ...)
