Build artifacts
Build artifacts are the result of running a pipeline in our Continuous Integration system.
We can register as many build artifacts as desired, so we can watch them along with our results in our CI system.
However, when talking about container based microservices, it's very common to build a container image at the beginning of the pipeline, and use this artifact to perform a certain set of tests.
Pushing container images to a container registry does not mean anything about delivery though, aside from the fact that those new container images are sitting on our container image registry.
