Yeah , if you use the Dockerfile, but pre-build images has tags and ID's that you can use to make sure you always get the same image. I see a few reasons to build your own from the Dockerfile: - 1) You don't trust the image and want to build your own. - 2) You want to build something slightly different - 3) You want an up-to-date version. 2) is often solved by building your own image with the changes, and I think 1) is solved by the Automated Builds (?), but I haven't used them yet.
