Running Android emulator in docker container

So,

Is it possible to run the (Android) emulator through Docker? yes.

I don't know much about Fastlane|wix/Detox, but I made this in a e2e/Appium project

If so, how?Do you need a hardware that support virtualization

1. In Linux find out if CPU Support Intel VT/AMD-V Virtualization For KVM

   lscpu | grep Virtualization

Virtualization: VT-x (if 'Intel VT-x' or 'VT-x' feature supported)

or

Virtualization: full (if 'full' not supported)

On AWS, you need a bare metal instance (supported x86) like c5.metal

2. Android Emulator Container Scripts

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

3. Follow this git, create an image with google API (I my case, 27-google-x86) and put in docker repo, like AWS ECR.

4. And, I created an image too to Appium (I believe with is possible with wix/detox)

5. To SDK

Dockerfile

5. Finally, I orchestrated everything a Jenkinsfile

This is what worked in the end BUT required bare metal machine
