I have been using ImageFromDockerFile to build images on the fly for my tests, which are supposed to be cleaned up by default.
However, I noticed that the images were being untagged and left as dangling images in most cases (see MicroShed/microshed-testing#9)
Currently Testcontianers registers shutdown hooks for:
However, it does not coordinate these shutdown hooks. Typically the remove image hook fires before the stop+remove container hook completes, which leaves the dangling images. To solve this, we can merge the two shutdown hooks into one and therefore guarantee containers are stopped+removed before we attempt to do the image removal.
