Clarification needed for docker builds and bundle https://github.com/DioxusLabs/dioxus/discussions/4248

There is a discussion of dioxus docker builds.

Could you clarify dependency caching mechanism and if it supported by dioxus as it uses its own target and building folders, thank you in advance.

Additionally could you clarify what the difference between build and bundle dx command? Is build + nginx is the same as bundle?
