Why does my docker container have files from a different image? - docker

Question

My application requires two docker files. I am building them with docker compose. The compose file is like this
version: '3.4'
services:
cors:
container_name: cors
image: cors:latest
build:
context: ./compose/cors-anywhere
dockerfile: Dockerfile
user: "node"
ports:
- 8081:8081
command: node server.js
vite:
container_name: vite
image: vite:lts
build:
context: ./compose/vite
user: "node"
tty: true
working_dir: /app
ports:
- "5173:5173"
volumes:
- ./vite/:/app
command: /start
cors' Dockerfile is like this
ARG NODE_VERSION=lts
FROM node:${NODE_VERSION}
ENV NODE_ENV=production
ENV NODE_PATH=/usr/local/lib/node_modules
ARG version=latest
RUN npm install -g cors-anywhere#$version
COPY server.js .
CMD ["node", "server.js"]
EXPOSE 8081
and vite's docker file is like this
ARG NODE_VERSION=latest
FROM node:${NODE_VERSION}
RUN npm install -g npm#latest
COPY ./entrypoint /entrypoint
RUN sed -i 's/\r$//g' /entrypoint
RUN chmod +x /entrypoint
COPY ./start /start
RUN sed -i 's/\r$//g' /start
RUN chmod +x /start
ENTRYPOINT ["/entrypoint"]
vite's entrypoint script is like this
#!/bin/bash
set -o errexit
set -o pipefail
set -o nounset
until cd /app && npm install
do
echo "Retrying npm install"
done
exec "$#"
After the images have been built, when the cors container comes 'up' it logs lots of errors because it is trying to run vite's entrypoint script. I don't understand why entrypoint has been copied to the cors image. Here is the file structure for the cors container

What am I not understanding?
