# fetch code

mkdir ~/redroid && cd ~/redroid
repo init -u https://github.com/remote-android/platform_manifests.git -b <REV> --depth=1
repo sync -c --no-tags
```

## Build
```bash
# create builder docker image (ubuntu 20.04)
# adjust apt.conf and source.list if needed
docker build --build-arg userid=$(id -u) --build-arg groupid=$(id -g) --build-arg username=$(id -un) -t redroid-builder .

# OR ubuntu 14.04 (old mesa3d release)
docker build --build-arg userid=$(id -u) --build-arg groupid=$(id -g) --build-arg username=$(id -un) -t redroid-builder -f Dockerfile.1404 .

# start builder
docker run -it --rm --hostname redroid-builder --name redroid-builder -v <AOSP-SRC>:/src redroid-builder

# *inside* builder container
cd /src

. build/envsetup.sh

lunch redroid_x86_64-userdebug
# redroid_arm64-userdebug
# redroid_x86_64_only-userdebug (64 bit only, redroid 12)
# redroid_arm64_only-userdebug (64 bit only, redroid 12)

# create redroid docker image in *HOST*
cd <BUILD-OUT-DIR>
sudo mount system.img system -o ro
sudo mount vendor.img vendor -o ro
sudo tar --xattrs -c vendor -C system --exclude="vendor" . | docker import -c 'ENTRYPOINT ["/init", "qemu=1", "androidboot.hardware=redroid"]' - redroid
