Need help installing Tubi for Channels docker

I use a Synology NAS with Docker. When I attempt to load this container (latest from GitHUB). this is Invalid. Does anyone know what I doing wrong? I have the Pluto and Frndly TV Containers running good.

What does that mean? Works for me

Compose

version: '3.9'
services:
  # GitHub home for this project with setup instructions: https://github.com/jgomez177/tubi-for-channels
  # Docker container home for this project: https://ghcr.io/jgomez177/tubi-for-channels
  tubi-for-channels:
    image: ghcr.io/jgomez177/tubi-for-channels:${TAG}
    container_name: tubi-for-channels
    volumes:
      - "/volume1/docker/tubi:/app/tubi_data"
    ports:
      - ${HOST_PORT}:${TUBI_PORT}
    environment:
      - TUBI_PORT=${TUBI_PORT}
    restart: unless-stopped

Environment variables

TAG=latest
HOST_PORT=7779
TUBI_PORT=7777

Clarify- When I download ghcr.io/jgomez177/tubi-for-channels:${TAG}. I get "Invalid Docker Repository"

What are you using to pull the image ?
It should be pulled as ghcr.io/jgomez177/tubi-for-channels:latest

I'm using the create new container, then entering add from URL since this is not in the docker registry.

In what?
I would recommend using portainer

Thanks. I will look into this.

You have probably worked around this by now, but the Synology Docker web interface is pretty basic. I would recommend enable SSH and install from the command line using the author's instructions. I also have a Synology NAS and this is what I do. The container will appear in Synology's Docker web app once you have installed it.

Thanks for your input. I have not been able to install the Tubi Container. I can't seem to find the command line. I have Ssh enabled but I lost as far as a Command line. I was able to install Pluto, Frndly TV and even Samsung TV containers. Any input would give me good direction. Based on what I understand, the Tubi container is not in the Docker registry which help me out greatly. Also, there is uncertainty about the Custom Channel set-up (m4u and EPG list) for Tubi.

docker run -d --restart unless-stopped -p 7778:7777 --name tubi-for-channels ghcr.io/jgomez177/tubi-for-channels

OK. Where do I enter this command? I use a Synology NAS and access this from my Mac Computer.

I recommend using Portainer. Nice GUI interface for managing docker images and containers.
They have a link to a video for installing on a Synology using ssh access here

You can also use Synology Task Scheduler to run the docker command as root to install Portainer instead of doing via ssh command line. (No need to go past Step 13)
