A Ubuntu 20.04 Docker image for building Android with systemd.
Development use only. Do not use in production!
Ansible roles often provide services. Testing these properly requires a service manager.
mkdir -p workspace tmp
sudo chown 1000:1000 workspace tmp # Add -h option if it's a symlink
sudo chmod 700 workspace tmp
docker-compose up -d
docker-compose exec ubuntu-androidbuild login -f ubuntu # Or docker exec -it ubuntu-androidbuild login -f ubuntu
Check the logs to see if systemd started correctly:
docker-compose logs
If everything worked, the output should look like this:
systemd 229 running in system mode. (+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD -IDN)
Detected virtualization docker.
Detected architecture x86-64.

To check for clean shutdown, in one terminal run:
docker-compose exec ubuntu-androidbuild journalctl -f
And in another shut down systemd:
docker-compose stop
The journalctl logs should look like this on a clean shutdown:
