Dockerfile added to build static files and serve with NGINX image

[michealch]

This PR includes a Dockerfile and .dockerignore that uses a two-stage build process: building static files with Node.js and serving them via a official NGINX image. The initial build stage uses node:lts to install dependencies and compile the application into static files. Second stage serve the static files with unprivileged NGINX Image.

Key Changes:

1. Implemented multi-stage build to separate build and runtime environments.
2. NGINX image for the runtime stage.

Build the Image by executing
docker build -t <image_name>:<image_tag> .

Run the Container by executing
docker run -p 8081:80 <image_name>:<image_tag>

The webpage should be accessible at http://localhost:8081

Hello @michealch
Thanks for your contribution.
When I try running this, I've got the following warning (although it is working as expected)

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Do you know why this warning appears?

@satnaing fixed the issue by replacing the distroless image with official nginx unprivileged image. it should work fine now :)

The sample image is built for just sample purpose and only compatible with amd64.

@satnaing i will create another pull request to update readme and add the docker infos to it. Feel free to contact me, if you have any question regarding Docker or Container.

[michealch]

i have updated runtime image to official nginx image. Please merge the PR.

Thanks for your contribution.
Can you also add some instructions in README in order to run this Dockerfile?

Hey @michealch

have you tried to use the docker-compose.yaml?
it will make you run astro paper on docker, you don't need to create a Dockerfile for this, or am I missing something here?

Hey @eerison
The docker-compose.yaml you have mentioned is for dev purpose and not for production. Dockerfile is there to build container image with static files for production purpose.
