aider: Updated Dockerfile to explicitly bind Jekyll to 0.0.0.0 and port 4000.

# Aider chat conversation:

USER: I did `git reset --hard HEAD~1` to discard the last edits. Please wait for further instructions before attempting that change again. Feel free to ask relevant questions about why the changes were reverted.

ASSISTANT: Understood. If you have any specific instructions or further changes you'd like to make, please let me know! If you have any questions about why the previous changes were reverted or need assistance with something else, feel free to ask.

USER: $ curl http://localhost:4000
curl: (52) Empty reply from server

ASSISTANT: The "Empty reply from server" error indicates that the server is not responding correctly. Let's troubleshoot this step-by-step:

1. **Check if the Jekyll server is running inside the Docker container**: Ensure that the Jekyll server is actually running and listening on port 4000 inside the container.

2. **Check Docker container logs**: Look at the logs of the running Docker container to see if there are any errors or issues.

3. **Verify the Dockerfile and scripts**: Ensure that the Dockerfile and scripts are correctly set up to start the Jekyll server.

Let's start by checking the logs of the running Docker container. You can do this by running:

```sh
docker ps
```

Find the container ID of the running Jekyll container, then run:

```sh
docker logs <container_id>
```

Please share any relevant log output here. This will help us diagnose the issue further.

USER: I ran this command:

 docker ps

And got this output:

CONTAINER ID   IMAGE            COMMAND                  CREATED              STATUS                                 PORTS                               NAMES

ASSISTANT: The status "Up About a minute (health: starting)" indicates that the container is running but the health check has not yet passed. This could mean that the Jekyll server is still starting up or there might be an issue preventing it from starting correctly.

Let's check the logs of the running Docker container to see if there are any errors or issues:

```sh
docker logs 4dbf5380b06e
```

Please share the relevant log output here so we can diagnose the issue further.

USER: I ran this command:

 docker logs 4dbf5380b06e

And got this output:

ASSISTANT: The logs indicate that the Jekyll site has been generated successfully, but it seems like the server might not be running or accessible. Let's ensure that the Jekyll server is running correctly and listening on the correct port.

One potential issue could be that the Jekyll server is not binding to the correct network interface. By default, Jekyll binds to `127.0.0.1`, which is not accessible from outside the container. We need to ensure it binds to `0.0.0.0`.

Let's update the `scripts/Dockerfile` to explicitly bind Jekyll to `0.0.0.0`:

scripts/Dockerfile
```dockerfile
<<<<<<< SEARCH
# Run Jekyll server
CMD ["jekyll", "serve", "--host", "0.0.0.0"]
=======
# Run Jekyll server
CMD ["jekyll", "serve", "--host", "0.0.0.0", "--port", "4000"]
>>>>>>> REPLACE
```

After making this change, rebuild the Docker image and run the container again:

```sh
bash scripts/build.sh
bash scripts/run.sh
```

Then try accessing `http://localhost:4000` again. If you still encounter issues, please let me know!
