it looks like the emulator step does not start

does docker hub support the privileged option and the /dev/kvm device?

thanks in advance for your reply.

it looks like kvm is not supported, so cannot run android emulator headless…
looks like GiHub can?

If it works on GitHub, then it indeed seems that way. Do you get any error message in the emulator container or do you have any error from Docker? Docker Hub supports emulation, but it doesn’t need /dev/kvm for that, only qemu as far as I know. If it is not enough fo the android emulator and kvm is not enabled on the machine that Docker Hub gives you to build the image,. it will not work.
