Unknown flag: -c

[samheutmaker]

I'm trying to use docker-protobuf as a base image for a typescript application. The image builds fine, but when trying to run I am confronted with the error "Unknown flag: -c". I've been debugging for a few hours, making sure my dependencies and system are update-to-date, etc but haven't had any luck.

My docker file is below:

FROM znly/protoc:latest

RUN apk add --no-cache --virtual .build-deps \
  bash \
  gcc \
  musl-dev \
  openssl \
  git \
  make \
  g++ \
  python \
  libcap


RUN apk add --no-cache nodejs-npm && \
  npm install protobufjs

# set the code directory
ENV CODE_DIR /opt
WORKDIR $CODE_DIR

# allow node to bind to port 80
RUN setcap 'cap_net_bind_service=+ep' /usr/bin/node

# create unprivileged user
RUN addgroup -g 1000 -S node && \
  adduser -u 1000 -S node -G node
RUN chown -R 1000:1000 $CODE_DIR
USER node

COPY --chown=1000:1000 package.json package-lock.json $CODE_DIR/
RUN npm install

COPY --chown=1000:1000 . $CODE_DIR

RUN npm run build

CMD npm run start

Any help is greatly appreciated.
