I'm new to Docker and trying to run a command in n8n that downloads media from a given link using yt-dlp. However, I'm struggling to persistently install yt-dlp in the n8n container. I can manually install it while in the container, but that doesn't save my changes. Here's my compose.yml for reference:
version: '3.8'
services:
n8n:
image: n8nio/n8n:latest
container_name: n8n
restart: unless-stopped
ports:
- "5678:5678"
environment:
- TZ=Europe/Berlin
- GENERIC_TIMEZONE=Europe/Berlin
- N8N_HOST=0.0.0.0
- N8N_PORT=5678
- N8N_PROTOCOL=http
- WEBHOOK_URL=https://n8n.xxx.de
volumes:
- n8n_data:/home/node/.n8n
- /volume1/data/media/music:/music
- /volume1/data/media/dreifragezeichen:/dreifragezeichen
- /volume1/data/media/videos:/videos
- /opt/nextcloud-data/xxx/files/yt-dlp:/yt-dlp
volumes:
n8n_data:
Any help would be greatly appreciated!

Why not consider using a separate container just for yt-dlp? This can help keep your services isolated and easier to manage since you can maintain them individually without conflicts.
To persistently install yt-dlp, you will need to create a custom Docker image rather than using the default n8n image. Start by creating a Dockerfile where you define how to install yt-dlp. Your Dockerfile should look something like this:
```
FROM n8nio/n8n:latest
RUN apt-get update && apt-get install -y yt-dlp
```
Then, update your compose.yaml file to reference this new image:
```
image: my-image-name:1.0.0
build: .
```
After that, build the image with `docker-compose build n8n` and run it with `docker-compose up -d`. This way, yt-dlp will be part of your n8n container!
Another option is to use the `dockerfile_inline` feature in your compose file, which allows you to keep everything in a single configuration. Just make sure to adjust the `pull_policy` accordingly!
But how would you manage the interaction between the containers? You'd need to allow access to the Docker socket or use some form of IPC which isn't typically recommended, unless n8n can handle that efficiently.
