At least 250GB of free disk space to check out the code and an extra 150 GB to build it. If you conduct multiple builds, you need additional space.
At least 16 GB of available RAM is required, but Google recommends 64 GB.

Sync Code

ReDroid manifest include several branches / tags:

redroid-12.0.0 / refs/tags/redroid-12.0.0_rxxxxxx
redroid-11.0.0 / refs/tags/redroid-11.0.0_rxxxxxx
redroid-10.0.0
redroid-9.0.0
redroid-8.1.0

# 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

#### If repo is not foud

sudo apt-get install repo


# if is not working go manually
mkdir -p ~/.bin
PATH="${HOME}/.bin:${PATH}"
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
chmod a+rx ~/.bin/repo 

#/usr/bin/env: ‘python’: No such file or directory
#python3 need to be installed and added to path, for unbuntu 20.04 you can go away with this
sudo apt-get install python-is-python3

Build

# create builder docker image (ubuntu 20.04)
# adjust apt.conf and source.list if needed
# if root delete (``N groupadd -g $groupid $userid ...```)
docker build --build-arg userid=$(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 
docker run -it --rm --hostname redroid-builder --name redroid-builder -v <AOSP-SRC>:/src redroid-builder

# *inside* builder container
cd /src

. build/envsetup.sh

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

m

# create redroid docker image in *HOST* (you need to exit the container)
# example path of "<BUILD-OUT-DIR>" - redroid/out/target/product/redroid_x86_64
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

# create rootfs only image for develop purpose
tar --xattrs -c -C root . | docker import -c 'ENTRYPOINT ["/init", "qemu=1", "androidboot.hardware=redroid"]' - redroid-dev

Build with GApps

You can build a ReDroid image with your favorite GApps package if you need, for simplicity there is an example with Mind The Gapps.

This is not different from the normal building process, except for some small things, like:

When following the "Sync Code" paragraph, after running the repo sync, add this manifest under .repo/local_manifests/mindthegapps.xml, for the specific ReDroid revision selected.

For example, for Redroid 11 the revision is 'rho', and for Redroid 12 is 'sigma', and this is the expected manifest:
```
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
        <remote name="mtg" fetch="https://gitlab.com/MindTheGapps/" />
        <project path="vendor/gapps" name="vendor_gapps" revision="sigma" remote="mtg" />
</manifest>
```
Add the path to the mk file corresponding to your selected arch to device/redroid/redroid_ARCHITECTURE/device.mk , for example we want x86_64 arch (x86 for ReDroid 11 as in 'rho' Mind The Gapps as only x86 GApps)
```
$(call inherit-product, vendor/gapps/x86_64/x86_64-vendor.mk)
```
putting this, modified for the corresponding architecture you need. So change 'x86_64' with arm64 if you need arm64 GApps.

Resync the repo with a new 'repo sync -c --no-tags' and continue following the building guide exactly as before.
OPTIONAL but recommended. While importing the image, change the entrypoint to 'ENTRYPOINT ["/init", "qemu=1", "androidboot.hardware=redroid", "ro.setupwizard.mode=DISABLED"]' , so you avoid doing it manually at every container start, or if you want set ro.setupwizard.mode=DISABLED at container start, skipping the GApps setup wizard at ReDroid boot.
