Create container for building own Anbox images

The following discussion from !956 should be addressed:

I'd like to create our own Android image to use, but the effort to produce it with pure Alpine is not worth it.
Instead I suggest we write down the exact steps to produce such an image, and make a Docker/Podman/LXC container which automatically executes those and produces a working image. We can then upload it somewhere for anbox-image to use.

changed title from Create our own Anbox image to Create container for building own Anbox images

I think we have sort of decided to use the newer Anbox images I have compiled locally for now.

The main difference to the prebuilts from Anbox is that they are all based on the latest Anbox source (so they should behave similarly). I have also rebased the Anbox patches on top of a new Android tag (was trivial, no conflicts), so they are built upon Android 7.1.2 with security patch level October 2019 (instead of 7.1.1 and January 2017).

It would still be useful to have some sort of container to build them. I have changed the issue title accordingly. I don't have much experience with container stuff myself.

Some inspiration for a possible git repo:

.gitignore
Dockerfile
run.sh
build-image.sh
build/

• Dockerfile: describes the build environment, ideally just Alpine or Debian or whatever is suitable, with next to nothing on top.
• run.sh:
  • builds the docker container
  • creates "build" dir
  • runs docker run with
    • build dir mounted (rw)
    • build-image.sh mounted (ro)
    • executes build-image.sh, passing all arguments ("$@")
• build-image.sh:
  • take arch as parameter?
  • downloads/clones all dependencies that don't exist, but update the ones that do exist
  • start build

I've settled for using a ubuntu/debian chroot. I've tried with Ubuntu 16.04 LTS Xenial Xerus so far (outdated OS, outdated build OS I guess, the AOSP setup page only listed 14.04 and older). The only dependencies needed on the host are debootstrap and arch-chroot. Both are present on Alpine.

setup:

sudo apk add -t .anbox-image debootstrap cmd:arch-chroot
sudo debootstrap --variant=buildd --arch amd64 xenial /var/chroot/xenial http://archive.ubuntu.com/ubuntu/
sudo arch-chroot /var/chroot/xenial <<EOT
apt update
apt install -y git-core gnupg flex bison libgoogle-perftools4 build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip gawk python sudo cpio squashfs-tools openjdk-8-jdk
useradd build -m -s /bin/bash
su build -c "mkdir ~/source ~/out"
EOT

build (assuming the code is at ~/anbox-image):

sudo mount ~/anbox-image --bind -o ro /var/chroot/xenial/home/build/source
sudo arch-chroot /var/chroot/xenial <<EOT2
sudo mount /home/build/out --bind -o rw /home/build/source/out # building out of tree is broken
sudo -u build /bin/bash <<EOT
export LC_ALL=en_US.UTF-8
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
cd /home/build/source
. build/envsetup.sh
lunch anbox_x86_64-userdebug
make -j8
EOT
EOT2

make an image (with a patched create-package.sh):

sudo arch-chroot /var/chroot/xenial <<EOT
cd /home/build/source/vendor/anbox/
scripts/create-package.sh /home/build/source/out/target/product/x86_64/ramdisk.img /home/build/source/out/target/product/x86_64/system.img
EOT

I think I'll make a Makefile out of this. @ollieparanoid is there some kind of procedure to create a repo?

Wow, that's shocking

The scripts look good though.

is there some kind of procedure to create a repo?

ask Martijn or me to create the repo. How should it be called? :)

By Oliver Smith on 2020-04-11T22:42:41

I don't have a good idea for the name. Anbox Image Makefile? pmOS' Makefile for Anbox image? whichever sounds best to you I guess :-)
