Technology
This guideline shows how to run redroid on Android-x86.
Introduction
Redroid:
ReDroid (Remote anDroid) is a GPU accelerated AIC (Android In Container) solution. You can boot many instances in Linux host (Docker, podman, k8s etc.). ReDroid supports both arm64 and amd64 architectures. ReDroid is suitable for Cloud Gaming, VMI (Virtual Mobile Infrastructure), Automation Test and more https://github.com/remote-android/redroid-doc#overview
Android-x86:
Run Android on your PC. This is a project to port Android Open Source Project to x86 platform, formerly known as “patch hosting for android x86 support”.

Building Android-x86
We use pie(based on aosp9) for startup:
# mkdir android-x86
# cd android-x86
# repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b pie-x86
# repo sync --no-tags --no-clone-bundle -j18
Or:
repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b pie-x86 -m android-x86-9.0-r2.xml
repo sync --no-tags --no-clone-bundle
repo size:
# du -hs android-x86/
79G android-x86/
# ls android-x86/
Android.bp bionic bootstrap.bash compatibility dalvik device frameworks kernel libnativehelper packages platform_testing sdk test
art bootable build cts development external hardware libcore Makefile pdk prebuilts system tools
Make modification for rootdir, the aim is for enable binderfs:
# vim ./system/core/rootdir/init.rc
mount configfs none /config nodev noexec nosuid
chmod 0770 /config/sdcardfs
chown system package_info /config/sdcardfs
+ # Mount binderfs
+ mkdir /dev/binderfs
+ mount binder binder /dev/binderfs stats=global
+ chmod 0755 /dev/binderfs
+
+ # Mount fusectl
+ mount fusectl none /sys/fs/fuse/connections
+
+ symlink /dev/binderfs/binder /dev/binder
+ symlink /dev/binderfs/hwbinder /dev/hwbinder
+ symlink /dev/binderfs/vndbinder /dev/vndbinder
+
+ chmod 0666 /dev/binderfs/hwbinder
+ chmod 0666 /dev/binderfs/binder
+ chmod 0666 /dev/binderfs/vndbinder
Build via:
# . build/envsetup.sh; lunch android_x86_64-userdebug
# make iso_img TARGET_PRODUCT=android_x86_64 -j128
Examine the build out iso files:
# ls -l -h out/target/product/x86_64/android_x86_64.iso
-rw-r--r-- 1 root root 725M Feb 5 02:02 out/target/product/x86_64/android_x86_64.iso
Customization kernel
customize the kernel via(See last section kernel configuration):
# cd kernel
# make android-x86_64_defconfig
# make menuconfig
##### After make customization
# cp arch/x86/configs/android-x86_64_defconfig arch/x86/configs/android-x86_64_defconfig.back
# cp .config arch/x86/configs/android-x86_64_defconfig
Re-build the kernel and re-gen iso:
# cd kernel
# make mrproper
# cd ..
# . build/envsetup.sh; lunch android_x86_64-userdebug
# rm $OUT/obj/kernel/arch/x86/boot/bzImage
# make iso_img TARGET_PRODUCT=android_x86_64 -j128

Enable docker
Enable wifi:
adb root and re-connect:
# adb connect 192.168.122.232
connected to 192.168.122.232:5555
# adb -s 192.168.122.232:5555 root
restarting adbd as root
# adb connect 192.168.122.232
connected to 192.168.122.232:5555
Create folder structure:
# adb shell
x86_64:/ # mkdir /data/var
x86_64:/ # mkdir /data/docker/
x86_64:/ #
Download docker-ce binary files from https://, extract them and upload them
to android-x86 machine:
# adb push ~/Code/docker/* /data/docker/
Prepare the dockerd running environment in adb shell:
mount -o remount,rw /
ln -s /data/docker/* /bin/
ip rule add pref 1 from all lookup main
ip rule add pref 2 from all lookup default
ip route add default via 192.168.122.1 dev wlan0
ip rule add from all lookup main pref 30000
