I'm trying to create a python docker container from a python script of github. It's a script for Immich Webdav Server. I'm able to create the docker image with command "docker build -t app" . When i attempt command "docker run app" i get an error saying values must be set. According to the requirements only the .env file needs it and i still get the same error. I've tried putting the info in the app.py file and still the same error.

 

I'm just a noob trying to build this container, so forgive me if i missed something here. Any help i would really appreciate.

Following this guide/topic @ post 4 on how to build and run container

 

Github script

 

https://github.com/PersistentCloud/immich-webdav-wrapper?tab=readme-ov-file 

 

 

you may need ot add data to your .env file in the path. usualy when youy call adocker build to make a image it has a iamge name... is it called app????

...

 

The error indicates that the required environment variables (IMMICH_URL, IMMICH_API_KEY, and ALBUM_IDS) are not set in the Docker container, and the application (app.py) cannot run without them.

Here's how you can address the issue and run the Docker container with the necessary environment variables:

 

1. Define the Required Environment Variables

You need to provide values for the following variables:

IMMICH_URL: The URL of your Immich server.

IMMICH_API_KEY: The API key for accessing Immich.

ALBUM_IDS: One or more album IDs required by the application.

If you're not sure what these values should be, consult the documentation or developer of the application for guidance.

 

2. Run the Docker Container with Environment Variables

You can pass the environment variables when running the Docker container. For example:

docker run -e IMMICH_URL="http://your-immich-server-url" \
           -e IMMICH_API_KEY="your-api-key" \
           -e ALBUM_IDS="album1,album2" \
           app

 

 

3. Use an .env File for Simplicity

Create a .env file in the same directory where you built the Docker image, and add the required variables:

IMMICH_URL=http://your-immich-server-url
IMMICH_API_KEY=your-api-key
ALBUM_IDS=album1,album2

docker run --env-file .env app

 

4. Modify the Dockerfile (Optional)

If these environment variables will always have fixed values, you can define them in the Dockerfile itself. Add the following lines to your Dockerfile:

Dockerfile

add:

ENV IMMICH_URL=http://your-immich-server-url
ENV IMMICH_API_KEY=your-api-key
ENV ALBUM_IDS=album1,album2

rebuild to call it app:
 

docker build -t app .

then call docker run app asuming no errors...

5. Verify the Environment Variables in the Container
docker run -it app /bin/bash
Once inside, inspect the variables:
 

echo $IMMICH_URL
echo $IMMICH_API_KEY
echo $ALBUM_IDS
