I'm trying to learn my way around Kubernetes with Google Cloud Platform. I have a small Vue-based application working locally with the following Dockerfile and docker-compose.yml.

Building and bringing up this project locally works great. However, when using kompose up to create a deployment/svc/etc. for this thing, the container fails to build properly. Ultimately it ends up in a crashing loop.

Inspecting the logs shows that the issue is that npm cannot find /opt/eyeball/package.json or /opt/eyeball/package-lock.json. I'm confused since this isn't an issue when I build and push the image that my cluster is ultimately pulling down - those files are right where you'd expect them to be based on my Dockerfile. Any idea why this might be happening?

Dockerfile

FROM node:8-alpine
RUN apk --no-cache --update add gzip
RUN mkdir -p /opt/eyeball
ADD ./package.json /opt/eyeball
ADD ./package-lock.json /opt/eyeball
WORKDIR /opt/eyeball
RUN npm install
ADD . /opt/eyeball

docker-compose.yml

version: '3'
