I've been trying to install docker in the alpine dockerfile, on my local copy of the repository:
FROM alpine:latest
RUN apk add --no-cache linux-virt openrc docker
RUN rc-update add docker boot
RUN echo "root:root" | chpasswd
The problem I have currently is that, when the VM boots, the docker service cannot start. It seems to be unable to create mandatory files:
I know that I can make the filesystem writeable and successfully start the service with this script:
mount -o remount,rw /
service docker start
However, I simply cannot afford to be forced to run this every time I want to use the image! Simply rebooting makes the filesystem read-only again...
Is there a way to tell qemu to mount the file system as rw, or update the image configuration from the builder container to automate this process?
