Hey @MulongDeng
I'm sorry to hear that you're having troubles with oakctl app building. Could you write down the specific issue you're having?
We would like people to use oakctl for deploying standalone apps, but right now it can be annoying to use especially when you have to iterate a lot on your build_steps.
Recently we have implemented an oakctl app exec -i <cmd> command, which allows you to get an interactive shell in the container and thus makes it much easier to iterate on your build_steps and debug in general. This command will become supported in an OS release within the next two weeks.
So, back to the problem at hand. Docker is currently miss-configured on the OS as it stores all of it's data in temporary storage, which is wiped upon reboot.
To combat this you can perform the following steps on the device side:
systemctl stop docker
mkdir /data/docker-data
echo '{"data-root": "/data/docker-data"}' > /etc/docker/daemon.json
systemctl start docker
from here on out images and containers will persist accross reboot.
Thanks,
Filip
