Doing a reproducible build with Vagrant and Docker is possible but very far from straight forward as you have to make extra sure that you use the exact same source box/image and install every software in the exact same version and deal with updates manually (and while most of the time updates don't break stuff anymore, it still happens at least once a year) + you still have to deal with synchronizing your IDE settings, secrets & credentials which you don't want baked into a Docker image, ... again yes it's possible, but not as straightforward as working in the exact same environment... the VM on an external SSD is a better solution, but then it's still something you have to carry with you even though it's more compact than a laptop...
