Someone is attempting to deploy a commit to a Personal Account owned by @ddiu8081 on Vercel.

@ddiu8081 first needs to authorize it.

Thanks! I'm totally new to Docker, but I think you're doing the right thing!

I'm still working on a few things and will merge it soon.

I think the Dockerfile should be modified to look like this, because if the host is not specified, the internal services in Docker will only listen on localhost and cannot be mapped outside.

FROM node:alpine
RUN mkdir -p /usr/src
WORKDIR /usr/src
COPY . /usr/src
RUN npm install
EXPOSE 3000
CMD npm run start -- --port 3000 --host 0.0.0.0
