Running Pynecone in Docker

[mattcaruso]

Hi folks. I'm starting my first Pynecone project and am having some trouble debugging my Dockerfile to get it up and running. So far, I have Python and Node installed in the container, but am now having trouble getting bun to work correctly. I don't see any example Dockerfiles in the discussions yet, so I thought this would be a helpful conversation to have in public.

So far, my Dockerfile:

FROM python:3.9-slim-buster
WORKDIR /app
COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt

# Install node.js using nvm
ENV NODE_VERSION=16.13.0
RUN apt-get update && apt-get install -y curl
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
ENV NVM_DIR=/root/.nvm
RUN . "$NVM_DIR/nvm.sh" && nvm install ${NODE_VERSION}
RUN . "$NVM_DIR/nvm.sh" && nvm use v${NODE_VERSION}
RUN . "$NVM_DIR/nvm.sh" && nvm alias default v${NODE_VERSION}
ENV PATH="/root/.nvm/versions/node/v${NODE_VERSION}/bin/:${PATH}"
RUN node --version
RUN npm --version

COPY . .

CMD [ "pc", "run"]

Which is creating this error when I run the container:

Hi you will need to pc init your repository before you run, we automatically install bun for you if you do not have it when you run pc init.

Something like this:

$ mkdir my_app_name
$ cd my_app_name
$ pc init

And then:

$ pc run
