rc-update missing in alpine:>=3.3

[u6f6o]

Hi,

I created the following Dockerfile:

FROM alpine:3.3

RUN apk update \
    && apk upgrade \
    && apk add bash curl openvpn iptables \
    && rm -rf /var/cache/apk/* \
    && rc-update add openvpn default \
    && echo "tun" >> /etc/modules

but starting from alpine:3.3 it fails because rc-update cannot be found:

docker build -f Dockerfile .
Sending build context to Docker daemon 2.048 kB
Step 1 : FROM alpine:3.3
 ---> 47cf20d8c26c
Step 2 : RUN apk update         && apk upgrade  && apk add bash curl openvpn iptables   && rm -rf /var/cache/apk/*      && rc-update add openvpn default        && echo "tun" >> /etc/modules

The rc-update command is part of the openrc package so you should install this, too. Also note that you may want to use the --no-cache parameter of apk.

If you don't know https://github.com/just-containers/s6-overlay, it might be worth to have a look at it as a replacement for openrc.

Cool, thx for the quick response, I'll have a look at it today.

Thanks for saving time. It worked like a charm after installing $ apk add openrc
