• Mar 13 · 6 min Docker as a CI Build System In my current position, we define continuous integration builds for all our projects in a Dockerfile. For us, Docker provides a set of guarantees that are perfect for CI. Docker builds are reproducible. Docker is available on every major OS. Docker produces universal artifacts. Builds are Reproducible Everywhere A standard Jenkins build runs directly on the system. It’s nothing against Jenkins, but if you are just building on a raw node, the underlying instance will have discrepancies. This could be security patch, library versions, or even OS versions. For us, a runner might be Ubuntu or OSX. This means out of date local packages cause build failures. Don’t get me wrong, that’s a worst case scenario. Worst case always happens in DevOps. tags ~ devopsdockercontinuous integration
