Help with Docker on Raspberry Pi

Playground Custom Channels
#1

So I am definitely not super familiar with linux but I am comfortable working in command line provided someone helps me with the syntax and such.

So I've got my Raspberry Pi setup with a static IP on my network, I think I have Docker installed correctly because if I run: "sudo docker version" I get a reply with 20.10.0 for version number.

I ran the docker commands as I found somewhere else and I think it's worked because when I attempted: "sudo docker run --restart unless-stopped --name pluto-for-channels -p 8080:80 jonmaddox/pluto-for-channels" and it returns essentially "Conflict. The container name "/pluto-for-channels" is already in use.

So I think the Docker container is running appropriately but when I put "http://raspberryip:8080playlist.m3u" in the server settings but it doesn't seem to find any channels.

Any help?

You need the full url for the playlist.m3u

Something like http://XXXXXXX:8080/playlist.m3u

The XXXXXXX being the ip (or name if you have it setup to be addressable this way) of the RPi

Try the url in a web browser (that can reach the RPi) and see if it populates or gives an error.

#3

Yeah, sorry, the forum removed a tag I used in attempting to show the IP.. I did use the IP for the RasperryPi. It's 192.168.86.10

When I try to connect to that from my phone I do get an error that it can't be reached. My routed definitely identifies the Raspberry Pi with that IP and on the RaspberryPi if I use "hostname -I" it returns: 192.168.86.10 172.17.0.1

Does docker ps show it as running?

You can try docker stop pluto-for-channels && docker rm pluto-for-channels then try to recreate it.

It should show you it's running when you click http://192.168.86.10:8080

#5

If I don't use "sudo" none of the commands work. But "sudo docker ps" does not show any containers running.

Running the stop command and then re-running the original docker run --restart unless-stopped......." did show it pulling EPG data and follows with "SUCCESS Wrote EPG to epg.xml!" and "SUCCESS Wrote the M3U8 tuner to playlist.m3u8"

And when I just tried from my phone it downloaded the m3u file so give me a couple minutes to check the server and play from the nvidia shield.

#6

I think you're missing a -d on that run command.

#7

It does seem to be working right now (without the -d).

What does the -d part of the command do, and should stop the Docker and restart it again with the -d?

#8

It puts it in the background so it keeps running

#9

10-4. I'll stop it and re-start. I'll also need to relocate the Raspberry PI and power it off, does the Docker container restart automatically?

Just tried to stop and rerun it adding the -d and I get a "Conflict. The container name /pluto-for-channels is already in use" error but docker ps doesn't show any containers running.

#10

Just wanted to thank everyone, I believe I have it working. It's downloaded the channels and the guide data. Let's hope my Pluto Channels don't drop like they did on the other m3u file.

I did have to run "docker system prune" to delete the non -d container. But I just recreated it with the correct command and all seems good.

Is the docker install on tap for the dedicated Pi image?

#12

Docker is installed already on the RasPi DVR image so this is super easy to accomplish. If you enable SSH access per tmm1's instructions from the RaspberryPi page (BETA: Channels DVR Server for Raspberry Pi 4 (USB BOOT IMAGE)), then ssh in and run the command listed in the "Setup" section on the Pluto Project page (https://github.com/maddox/pluto-for-channels#set-up) you should be up and running. Run "docker ps" to verify.

docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e8fae16b667a jonmaddox/pluto-for-channels "/usr/src/app/entryp…" 3 hours ago Up 3 hours 0.0.0.0:8080->80/tcp pluto-for-channels

Then just follow the rest of the Pluto instructions to set it up. For the least friction this may be the simplest DVR to set Pluto up. (Edit: the Docker command is set to persist across reboots so I removed my question about starting this on boot)

Recording PLUTO using Raspberry PI

I am having some trouble as well. I tried to follow the directions to set up SSH on the Raspberry Pi, but when I try to SSH in, I get the following message:

Permission denied (publickey)

Is there a way to re-set all of the SSH stuff so I can try and start over. I am a total newb at this and that's why I LOVE the pre-done Pi disk image. Just trying to get the Pluto channels installed.

Thanks, in advance for the help.

Have you followed the instructions here:

#15

I tried that but I think I put the wrong key on the USB drive. I re-did it, but it still doesn’t seem to be working. I’m wondering if the old file is being used.

Sorry, again total noob.

#16

Is your drive formatted FAT or NTFS and named CONFIG (case sensitive?)

If so delete everything on it and start again.

I had trouble with ed25519 and had to start again with RSA, but it should work.

https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#platform-mac

Steps 1, 2 and 3.

I had better success with

https://kb.iu.edu/d/aews

Step 1 and then step 6 to your USB drive.

#17

Thank you so much!! That solved the issue. I used the second link you added, generated with RSA and it's working now. Again, thanks!!
