Android Emulator on GCP

Is it possible to run an Android emulator using docker?

Yes, it's possible. Below are three example repositories and docker images available:

• KVM must be enabled.

• Run apt-get install cpu-checker and kvm-ok.

• https://github.com/google/android-emulator-container-scripts

  • Docker image provided by Google
  • Runs the docker emulator. Remote adb connection needs to be set up separately.
  • Additional steps are required for screen access.

• https://github.com/budtmo/docker-android

  • Runs the docker emulator and allows control through a web interface.

• https://github.com/amrsa1/Android-Emulator-Docker

  • Runs the docker emulator and allows control via VNC client.

Is running a docker emulator possible on GCP?

Yes, it's possible. GCP supports nested virtualization.

• KVM is available.
• enableNestedVirtualization option must be set via API (https://cloud.google.com/compute/docs/instances/nested-virtualization/enabling).
• Tested with https://github.com/budtmo/docker-android, it works but performance may not be optimal.
  • It may be usable considering some sluggishness.
  • However, it seems that a more powerful setup is needed. Even with 16 vCPUs and 14.4GB of memory, it still felt sluggish.

What are the alternatives to improve GCP docker emulator performance?

1. Run the emulator directly on a GCP VM instance (without containerizing it).
2. Verify performance on a GCP GPU-enabled instance.
3. Proceed with building a container-optimized OS (COS) with KVM enabled.
   • Refer to https://github.com/google/android-emulator-container-scripts/blob/master/cloud-init/README.MD.
   • Build a docker container optimized image with KVM support.
   • No pre-built images are provided.
   • Modify the config in the cos-src code on Linux, rebuild, and upload the VM Machine image directly to GCP.
     • Attempting this, but as of yesterday before leaving work, the build failed due to insufficient disk space despite having 30GB of free space.
