Sagetv docker on LinuxMint

[Galaxysurfer]

How would I install docker on LinuxMint Debian without unraid? I am not sure which steps of a regular linux install are cancelled by the use of a docker. Is there already instructions for this? If not can I get a rundown? I figured this would be easier that doing & VM and take up less resources.

Basically

Step 1: Install Docker
https://docs.docker.com/engine/insta.../linux/ubuntu/

Step 2: Install SageTV

docker run -d --name sagetv-server \
  -v LOCAL_MEDIA_DIR:/var/media \
  -v OPTIONAL_LOCAL_EXTRA_MEDIA_DIR:/var/mediaext \
  -v LOCAL_SAGETV_DIR:/opt/sagetv \
  --net host \
  --env OPT_GENTUNER=Y \
  --env OPT_COMMANDIR=N \
  --env OPT_COMSKIP=Y \
  --env PUID=1000 \
  --env PGID=1000 \
  --env VIDEO_GUID=44 \
  --env JAVA_MEM_MB=1024 \
  --privileged \
  -t -i "stuckless/sagetv-server-java8"

To shut it down...

docker stop sagetv-server
docker rm -f sagetv-server

the PUID and PGID should be the UID and GUID values of the user that running docker (all files will be owned by that local UID/GUID)

VIDEO_GUID should be video GUID of the video group

LOCAL_XXX places in the script should be the local locations on your computer.
eg,

docker run -d --name sagetv-server \
  -v /home/sagetv/media/:/var/media \
  -v /home/sagetv/othermedia/:/var/mediaext \
  -v /home/sagetv/appdata/:/opt/sagetv \
  --net host \
  --env OPT_GENTUNER=Y \
  --env OPT_COMMANDIR=N \
  --env OPT_COMSKIP=Y \
  --env PUID=1000 \
  --env PGID=1000 \
  --env VIDEO_GUID=44 \
  --env JAVA_MEM_MB=1024 \
  --privileged \
  -t -i "stuckless/sagetv-server-java8"

Question: what's the purpose of VIDEO_GUID:

VIDEO_GUID should be video GUID of the video group

Does a video group need to be manually created?

--thanks

[Brewer]

Ok, looked at all groups in system and see the video group I think you are referring to:

video:x:44:

So how is this used in sage? I currently have mine set incorrectly and wonder what the ramifications are.

[stuckless]

Because the Docker image is running as a "sagetv" docker user and is part of the "video" group there, we need to sync their video group to the host video group for permissions.

This is really only important if you are using an HDPVR or other video card that exposes a /dev/videoX device to the docker container. If you are not using video devices then nothing to worry about. (Network encoders are handles completely different)

Ahh- I'm using HDHomeRun as tuner so not needed in my setup. Thanks for the explanation!

Let us know how this goes as it may be useful for other folks who may want to run SageTV in a Docker under versions of Linux other than unRAID.

Something to file away and play with on a rainy day...

https://github.com/portainer/portainer

Portainer is a GUI (web based) for managing docker instances. In a similar fashion as the unRAID Docker UI, Portainer, allows you to configure the volumes, ports, etc. They have their own template repostiory format, and in theory, we could publish SageTV there as well.

I have played with this and it's pretty nice. A little more involved than the simple unRAID one, but, still, better than a command line for most

Is there any reason to also use the SageTV Docker on Windows? I believe that you can run Docker on Windows as well as Linux.

Docker on Windows is a kludge. It basically runs CentOS in a Hyper-V VM and that runs the Docker server. It's not at all Windows native. By default it's given 2 CPU's and 2GB of RAM. I think you'd be better off just running native Windows SageTV or run the Docker on a bare metal Linux.

That's not true if you install CentOS from the app store on Windows 10. Then it's running on a translation layer called WSL. I still don't know if I would trust something that's production there, but it could be a real option in the future.

I'm talking about the official Docker for Windows install.

FYI, I've been using Docker/SageTV on Xubuntu 15.04 for quite a while with no problems. It's hosted on my old HP Mediasmart server hardware (migrated from WHS to Xubuntu).
