demo: Remove jq and sfdisk from etcd image
They are no longer needed as the mounting happens in the
mount container.
-# A dockerfile to build an etcd container image from the upstream one
-# with a script as entry point
FROM quay.io/coreos/etcd:v3.1.5
-# sfdisk and jq re required to mount the disk
-RUN apk add --no-cache sfdisk jq
-
COPY ./etcd.sh /
ENTRYPOINT ["/etcd.sh"]
