Docker won't let me set environment variables for Jupyter Lab

I’m creating a course that will require students to run some software called PyStan. It turns out that this is partially supported on Windows.

Someone gave me an idea to use Docker so that students wouldn’t have any issue getting the software they need to do assignments. The end goal is that students can do very little to get Jupyter Lab up and running on their own machines, with as little effort as possible.

I tried writing the following to be run with sudo docker compose up

version: '3'
services:
  ubuntu_anaconda:
    image: continuumio/anaconda3:latest
    container_name: ubuntu_anaconda
    environment:
      - LANG=C.UTF-8
      - JUPYTER_TOKEN=my_secret_token  # Set your desired token here
    ports:
      - "8888:8888"  # Expose Jupyter Lab port
    volumes:
      - ./data:/data  # Add this line if you want to mount a local directory to the container
    command: /bin/bash -c "/opt/conda/bin/conda install -y -c conda-forge pystan && /opt/conda/bin/jupyter lab --ip=0.0.0.0 --port=8888 --allow-root --NotebookApp.token=${JUPYTER_TOKEN}"

However, the first line of the output warns me that

WARN[0000] The "JUPYTER_TOKEN" variable is not set. Defaulting to a blank string.

I am using Docker version 25.0.3.

    The JUPYTER_TOKEN variable not being set in your Docker Compose
    file, you can either explicitly define its value or remove it if not
    needed. If setting a token, replace my_secret_token with your
    desired token. After updating the file, running sudo docker-compose up again should eliminate the warning.

    2.Using .env file:

    • Create a .env file in the same directory as your docker-compose.yml.

    • Define variables in the .env file (e.g JUPYTER_TOKEN=my_secret_token # Set your desired token ).

    • In docker-compose.yml, reference these variables using ${VARIABLE_NAME}
      syntax. Docker compose automatically reads variables from the .env file in the current directory.

    version: '3'
services:
  ubuntu_anaconda:
    image: continuumio/anaconda3:latest
    container_name: ubuntu_anaconda
    environment:
      - LANG=C.UTF-8
      - JUPYTER_TOKEN=${my_secret_token}
    ports:
      - "8888:8888"  # Expose Jupyter Lab port
    volumes:
      - ./data:/data  # Add this line if you want to mount a local directory to the container
    command: /bin/bash -c "/opt/conda/bin/conda install -y -c conda-forge pystan && /opt/conda/bin/jupyter lab --ip=0.0.0.0 --port=8888 --allow-root --NotebookApp.token=${JUPYTER_TOKEN}"

    As mentioned in the other answer you can use a .env file. You can also specify the token on the command line:

    JUPYTER_TOKEN=my_secret_token docker-compose up
