Image failed to build without modifyfs

[Xuanwo]

I failed to build image with following Dockerfile and options.

Version

:) makisu version
master-unreleased <-- It's 0.1.11 actually.

Dockerfile

FROM alpine:3.9
LABEL maintainer="Xuanwo <xuanwo@yunify.com>"

RUN apk add --no-cache --update openvpn dumb-init

VOLUME ["/etc/openvpn"]

EXPOSE 1194 1194/udp

ENTRYPOINT ["dumb-init"]

CMD ["/usr/sbin/openvpn", "--cd", "/etc/openvpn/", "--config", "config.ovpn"]

Did I miss something else?

if you do not have --modifyfs, then the functionality is very limited - you cannot use RUN in dockerfile.

[Xuanwo]

Well, I must miss the To build Dockerfiles that contain RUN, xxx statement, tks.
