ytdlwl-docker

Docker version of the ytdlwl project

Create docker image

clone this repository

git clone https://github.com/m1bcodes/ytdlwl-docker.git

Create Docker image:

docker build --tag ytdlwl ytdlwl-docker

Run docker image

Create a folder /srv/ytdlwl which will hold the downloaded files. Change owner accordingly.

For an interactive session:

docker run -v /srv/ytdlwl:/app/downloads --mount "source=ytdlwl-cookies,target=/app/cookies" -it ytdlwl sh

For test purposes: start the download by calling sh update_wl.sh.

installing the cookies

Running the docker image will create the volume cookies /var/lib/docker/volumes/ytdlwl-cookies. Place the cookies as described in the ytdlwl repository in the cookies folder.

running the docker image for real

docker run -d --name ytdlwl -v /srv/ytdlwl:/app/downloads --mount "source=ytdlwl-cookies,target=/app/cookies" ytdlwl 

To auto-start the container, e.g. after a reboot of the server, call

docker update --restart unless-stopped ytdlwl

rebuild for docker-compose

To rebuild the stack after editing and to avoid re-use of cached components:

docker-compose up --force-recreate --build -d

setup synchronization to remote systems

This section describes the steps required to synchronize the downloaded videos with remote (raspberry pi) systems. They can run libreelec for instance.

create key file

Execute these steps on the machine, where docker-compose is run. The remote machine is called rpi4 in this case.

ssh-keygen -o -a 100 -t ed25519

Allow the key file to be created in ~/.ssh.

copy key to remote machine

The public key is copied to the remote machine.

ssh-copy-id -i ~/.ssh/id_ed25519.pub root@rpi4

add all remote machines to a known_hosts file

In order to avoid confirmation by ssh to accept the remote machine, since no fingerprint is known, we create a known_hosts file, were the fingerprints of all machines are stored, which shall be syncronization targets. Type the folling command for each remote machine:

ssh-keyscan -H rpi4 >> ./known_hosts

The known_hosts file will be transferred as secret to the container.

install network tools on libreelec

Install the network tools addon (on libreelec) from the libreelec addon repository. The network tools can be found under program addons. This is necessary to have rsync available under libreelec.

rsync command

The rsync command to be executed from the ytdlwl container is added to update_wl.sh:

rsync -avz --delete -e "ssh -i /run/secrets/ssh-key-prv -o UserKnownHostsFile=/run/secrets/ssh-known-hosts" /var/Videos/Youtube_WL root@rpi4:"/storage/videos"

• The ssh key (we need the private one) is per docker-compose copied to /run/secrets/ssh-key-prv`
• --delete to remove extra files on the destination folder.
