Move image to alpine? #2

Open pwFoo opened 8 years ago

pwFoo commented 8 years ago

Could be easy to do and reduce the image size?

Tested qemu kvm with a simple alpine container

docker run --rm -ti --name kvm --cap-add NET_ADMIN -v /path-to-my-qcow2.img:/image/image.qcow2 --device /dev/kvm:/dev/kvm alpine sh
apk -U add qemu-system-x86_64 qemu bridge-utils dnsmasq

qemu-system-x86_64 -enable-kvm -cpu host -m 1024 -curses -drive file=/image/image.qcow2,format=qcow2,cache=none -usb -usbdevice tablet

Thank you for your feedback, pwFoo!

I have this in the roadmap, and I will move the image to a minimal container ASAP.

Tested it with the followin modifications.

dockerfile

FROM    alpine:latest

ENV     container docker

RUN     apk -U --no-cache add qemu qemu-system-x86_64 bridge-utils bash dnsmasq && rm -rf /var/cache/apk/*

COPY    startvm /usr/local/bin/startvm

RUN     chmod u+x /usr/local/bin/startvm \
        && mkdir /etc/dnsmasq.d

VOLUME  /image

ENTRYPOINT ["/usr/local/bin/startvm"]

-    -machine rhel6.0.0,accel=kvm,usb=off \

Reopened due to networking issues with Alpine container.

Master branch will still be built with Centos until everything is solved. After that, Alpine branch will be merged.

Some debug info for future investigation:
