/Octo-Print-Docker-Config

This is a Docker Compose file for setting up OctoPrint, a web interface for 3D printers. OctoPrint allows you to control and monitor your 3D printer from any device that has a web browser.

Code

version: '2'

services:

  octoprint:
    image: octoprint/octoprint:latest

    ports:
      - "5000:5000"

    environment:
      - TZ=America/New_York

    volumes:
      - /path/to/octoprint:/root/.octoprint

    devices:
      - /dev/serial/by-id/<dev_port_id>:/dev/ttyUSB0

    restart: unless-stopped

Changes to the Device Configuration

In version 2 of the code, the devices section has been updated to specify the location of the connected 3D printer.

The line - /dev/serial/by-id/<dev_port_id>:/dev/ttyUSB0 maps the USB device identified by the ID <dev_port_id> to the virtual device /dev/ttyUSB0.

Finding Your Connected Device

To find the ID of your connected 3D printer, you can use the following command:

ls /dev/serial/by-id/

This will display a list of all connected serial devices, along with their IDs. Find the ID of your 3D printer and replace <dev_port_id> with your device's ID in the devices section of the code.

Use

Copy and paste the code into a file named docker-compose.yml and use the following command to bring up the OctoPrint service:

docker-compose up -d

Final Thoughts

With this Docker Compose file and the updated device configuration, you should be able to set up OctoPrint and control your 3D printer from any device with a web browser. If you have any issues or questions, feel free to reach out for support.
