Hi @wuhuizuo — thank you for this PR, and apologies for the very long delay
before responding.

The patch can't apply cleanly anymore:

1. The --aptmirror plumbing flows through EmulatorContainer.__init__, whose
   signature has changed since 2021 (most recently in PR Surface API 33-37 and 16 KB-page system images #397). The mirror
   argument would need to be re-threaded.
2. js/jwt-provider/Dockerfile, one of the files modified here, was removed
   in commit 174ab2d ("Use Firebase for authentication."). That subsystem no
   longer exists.
3. The create_web_container.sh portion partially overlaps with PR emu/containers: return emulator ID if image is not available locally #390
   (merged), which already migrated that script to docker compose v2.

Closing rather than asking for a rebase.

Thanks again for the contribution and for raising the use case.
